As a former teacher, I'd like to commend you on your explanations. They are clear, free of anything that might be misunderstood (or else you explain those parts as you go), your pacing is slower as you reduce procedures into small increments, and you demonstrate your explanations with visuals. You're a natural. All so very helpful, thank you! :)

We recently upgraded our MacBook and I've taken this opportunity to collect all of our photos and transfer to the new machine. I knew nothing about the Photos app. Having watched many of your videos on this topic, I'm gaining a very good understanding. You present the information in your videos in a clear, concise manner that makes learning a lot of fun. Thank you for helping us all to get more out of our Macs! I'll be checking out much more of your content as I learn the new MacBook.

I have a better understanding of HEIC now! Thank you, Gary!!🥰

I had been wondering what the HEIC these files were about!

You did a great job explaining that, Gary! Thank you!

Bravo! 👏 The best overview of the HEIC format I have ever seen. Prior to today I wasn’t aware of your channel, but the KZfaq algorithm actually worked and recommended this video. And you have a new subscriber. 😃

Another nice one! I have been using heic for a while without knowing the background. I am now better informed. Thanks

Good to know details about this HEIC format, nice video. Thanks Gary.

This video is really good for your image(es) 😉 Thanks for all the interesting and well produced lessons. You are a real problem solver.

Thanks Gary! Hope all is well!

Thanks for the video! I like your flow without anxiety music on a background. There are so many noises in 2024, the guide needed to be quite, thank you for your kind and pleasure.

Thanks! I've been wondering about this for some time.

The wonderful thing about Gary, is that you can learn to drive a fomula 1 car Even if you don't yet know how to drive! Thank you Gary always pleasure to watch your tutorials !

Wow! Great video explaining these image types! Thank you!

Great video as always Gary!!

Thanks Garry. After watching this video and doing some experiments with the 14 Pro Max and finding that not all the iPhone lenses are created equal I have changed my shooting format to HEIF Max. Cheers

Thanks Gary, great explanation as always.

Brilliant as usual.

Thanks Gary. The only times I have an issue are sending pics to my Android friends, and that's also an MMS issue, and posting pics to a forum I'm a member of that uses the old VBulletin software and doesn't recognise any HE formats. I usually convert these in Finder, I didn't know they could be converted automatically in Mail, etc.

More recently taken photos will be using a newer device with significantly more pixels and HEIC will benefit them more than older, smaller photos.

Thanks Gary. So informative as always.

Brilliantly explained Gary!

Great explanation, thanks.

Thanks so much Gary!

Great explanation. Thanks!

Excellent explanation Gary. I have a better understanding of the situation.

Thanks Gary. I wondered what HEIC formatting was.

I always wondered. Now I know. Thanks!

A very helpful video. Thanks for sharing the information.

Excellent explanation, thanks Gary.

Fascinating stuff. Thanks Gary. You are a fount of knowledge!

Thanks Gary, nice and clear explanation.

The Windows Store has available HEIC converter for the photo viewer in Windows. Likewise, Samsung's S24 series will save photos to HEIC format.

Nice presentation, thanks

Good informative clip Gary. Thanks.

Excellent explanation.

Thanks very much, Gary, for this informative video! This was most interesting and helpful.

Excellent tutorial Gary! 👏

A very useful and informative video tutorial today! Very interesting! Thank you,Gary!👏🏻❤️

You read my mind on the converting question! 🤣 Thanks as always, Gary! 👌

Thanks Gary.

Thank you

Informative.

Never mind, I looked it up. When you take a photo on your iPhone or iPad, the image - or images, in the case of dual cameras and live photos - saves as an HEIC file. HEIC stands for High Efficiency Image Container. The format is an updated variant of the High Efficiency Image Format (HEIF), traditionally used by Apple across its mobile devices.

Very interesting - I wondered what HEIC ext was

Excellent

Fun fact: Bayer image sensors are not fully resolved like an ancient 3chip camera or a computer generated graphics file. A 12MP bayer sensor has 6MP green pixels, 3MP blue pixels, 3MP red pixels. So viewing a 12MP file as a true 12MP actually extrapolate, creates data that never existed to begin with. The raw file likely is three black and white images 6+3+3MP (12MP) images, as that’s what is captured by the sensor. Not much point pixel peeping a camera still image as the image literally is upscaled, more pixels/colors than the sensor that took the image :-)

I was literally scrolling down to the comments to ask about if Photos app can convert JPEG and H264 content to the newer format 😂 Thanks for the info Gary!

Another image compression format that I've been seeing more of is Google's WebP which is claimed to also maintain good quality and result in files smaller than jpeg. It would be interesting to see a comparison of HEIC and WebP.

6:34 -- thank you! i use both windows and mac and ifruit (iphone) and android and toggling this BACK to "more compatibility" will make me sleep better at night. thank you!! i have TB and TB of storage so i dont care about that -- for me i need compatibility! also thumbs up and this is the first time ive seen your channel. thanks youtube algorithm!

Thank you for the info! HEIC! Always wondered what that meant. But I had to send large amounts of photos to a client and they all went as HEIC. The client couldn't open them! I had to hand convert ALL the files to jpeg. Ugh! But this video helps with future transfers of photos and how to do it. Thank you Gary!

Great info... Thanks. (Containers FTW) Beers & Cheers from OZ

Making the files smaller actually encourages taking more pictures, which will drive up demand for larger storage devices, like in smart phones. But most phone vendors want to push something that costs PER month in a subscription, like cloud storage. As demand grows, so will the prices for onboard storage and for cloud storage as well. Any large vendor, like Apple, is very well aware of how to manipulate their user base; this is just one example.

My iPhone 15 Pro Max files still come over as HIEC files, even though the setting is set to "Most Compatible".

If you want to edit your photos, store your photos as lossless (like TIFF) or in raw format, so you don't get compression on compression. For editing videos, the preferred source format would be ProRes, while the end product can be in H264 or H265 (HEVC)

I've been wondering how to manage when I take large numbers of photos from my iPhone to my work Windows pc. I'll change the default setting in my work phone now! Thanks a lot! ☺

Several years ago my sister told me that an iPhone photo she took could not be opened by a Windows recipient, yet you say shared HEIC files are converted to JPEG format when shared. I do not know what she did, so I have not tried to duplicate her process. Instead, I told her to simply change the format in Camera settings, as you suggest.

This is very informative. What I've had a problem with is when I NEED to send a photo to say a DMV or IRS website they won't accept anything but a jpeg, so I have to convert it which means I have duplicates of those photos in HEIC and JPEG.

My vintage 2021 Samsung Galaxy A71 handles HEIC/HEVC just fine, so it's not just an apple iPhone thing.

In regards of images formats, wanted to ask if is there some format of background picture with real time metadata vector, I mean I would like to have a background image in my WebEx or Zoom videoconferencing but with image showing current time changing in my background scenario, for example a Wall watch, the time showed might be the local time of each assistant. I guess it will be an innovative format!

I like that they take up less space than JPEG. but I can't stand the fact that eBay won't let me upload them when I list items for sale. so I have to convert every single HEIC that I Airdrop to my MacMini. uggh.

One huge problem is the need to convert as many file users will not accept heic files. My health insurance co. is one such provider that only accepts jpeg files

You can open HEIC on Windows if you have the code from the Windows store on 10 and 11. For HVEC there's a fee for the codec but there used to be a way around it, not sure if it still works.

Nice video again Gary. Can you explain how to deal with Google's WebP images, how to view it or convert it in iMac?

I don’t think Apple looses out by implementing HEIC…or even HEVC. I think it’s more of balancing act as camera sensors get larger so do file sizes under the older formats. By shifting to more efficient file formats it offsets the increasing camera resolutions. So in the end maybe it’s closer to a wash. Plus as time goes on people tend to take more and more photos and videos. So storage requirements will still likely to increase, maybe just at a lower rate.

My 2019 iPad air stores photos I take in HEIF format, how does that differ from HEIC?

Thanks for the HEIC info, but it still seems like a hassle, I'll stick with JPG for now.

There are packages on Linux one can install to enable compatibility with HEIC files.

In Windows there was a free HEIC-format-programm to Install from the Microsoft Store for Free. But sadly now it costs. So I can't convince everyone in my family and all my friends to install it so they can see the heic-images. PS: I'm using a Samsung and they also have heic as their standard 👍🏻

Good day sir. about obsolete mac like imac 2014 that no longer be supported with new updates.. do you recommend recommend antivirus for additional security? i only use it for browsing and i do not install apps that i am not familiar with or outside appstore. i hope you can give advice

Hi Gary, related question.I have several thousand photos on my local hard drive. I want to use the Photo's app to 'manage' them but it always tries to store them in iCloud which I don't want. I do have my everyday phone snapshots in my iCloud account which is great and works well but I want my local photo's managed separately outside of iCloud. Is that possible?

So when you attach one or more photos to an email on iPhone and are asked what size you want to send it, which should you choose?

Hi Gary, I’ve always found file formats a bit confusing. I noticed that on my iPhone 14 the file is shown as HEIF which I suppose is the same?

I have mov files from an iPhone sent to my android, is there a way to convert those so i can play them

Hi Gary. You are such a talented presenter. Whilst there are denizens with lots of knowledge and lacking presentation skills and lecturers with insufficient knowledge and inability to teach, you are a multitalented individual and highly valued by your fans. I also watched your photos duplicates video and still trying to figure out how I managed to have thousands of duplicates on my Mac after switching from Windows to Mac. Would there be a way to establish where each duplicate is located before I delete/merge, as I always only place my photos into one folder? Hope this makes sense.

Ugh I don’t like using HEIC since it’s not compatible with some things.

I have that problem all the time. I receive lots of HEIC that I have to forward and people complain all the time they cant open it

I didn’t understand it before and I hated that when airdropping to mac to email it using a third party app it was A file that doesn’t open Up and apps didn’t support Heic. So do you recommend using it? On iPhone cam and also lets say for screenshots….

9:12 Now wait a minute. You say it would be compressing a compressed photo, but there’s a “lossless” option with HEIC. Do you still save disk space with that option?

The problem is that platforms haven’t caught up and you can’t upload the image

Can you open HEIC files in Photoshop and save them as jpegs?

Excellent video. However, you skipped right over something staring us all in the face; LOSSLESS! 4:01 I'd love to know how well that setting compresses the image, and how that compares to other lossless formats.

Why are people still using JPEG as opposed to JPG? What is the difference if any? Thx

You mention that Windows cannot open HEIC images. Can HEIC images be viewed on internet web pages by Windows users or must they be converted by Mac developers to a viewable format?

Hello garry sir can you please a video on how to make animated memes on mac and apps for i phone waiting for answer 😊 have a nice day

The billion dollars question is: will we see native support of the new formats on other operating systems and browsers? How long is the internet looking for a handy new format to reduce loading time and space consumption.

Great video! Is this why whenever I send a photo to my husbands pc, the physical size of the photo is different than the one on my iPhone?

these files reek havoc as my employees attach them to work orders, from their devices, yet I have to view and manage from a windows 7 server. god bless the march of technology and companies that refuse to move fw.

If converting jpg to heic is going to reduce file quality, then doesnt converting shares from heic to jpg cause similar degrading quality?

You didn't mention the fact that most photos are viewed in a small size on a website or even on a 4K monitor. Many pixels are thrown away at the time of display. The quality of the display also impacts the photo reproduction. A chain is as strong as its weakest link. The display and size of the photo is the "weakest link" when viewing a photo. Most people don't do pixel peeping.

So, a loss on quality going from Jpeg to HEIC. But no quality loss going from compressed HEIC to Jpeg? How? HEIC compression isn’t lossy?

We just need a non-lossy compression that efficiently works on these older file formats.

I do not like the HEIC because Google and Apple when to it and nothing open by default a win or linux pc. It took time to find a app to open it so you could convert it so you could use it. Try upload that file on a web site and you get FAIL. I think the format as a file is OK. It just a problem when nothing know what it is.

Thanks for the great tip! I asked ChatGPT to create a one-line command that converts all jpg, jpeg and png files in the current folder to HEIC. I'm freeing up space brutally. 😊 setopt nullglob && for file in *.(#i)jpg *.(#i)jpeg *.(#i)png; do sips -s format heic "$file" --out "${file%.*}.heic" && rm -f "$file"; done

Also the discussion of movies is very unclear. You compare 2 different movies. The 1st one is a .mov containing H.264 with a size is 23.6 MB. The 2nd is a mov containing HEVC with a size of 34.5 MB which after it's automatic conversion to H.264 results in 38.7 MB. So what is the lesson to learn in this example?

You can open an HEIC file on windows

Just had a little earthquake here....nice return to "normal". Thanks.

Great explanation! But saying that Apple is “loosing money” for our good and the good of all human kind…………… 😂

Isn't the quality lost during the conversion from HEIC to JPEG format? Yeah, wright it is...

8:45. Gary is correct here at the end of the video. It's pretty important point, and everyone should listen. Sequentially re-compressing files into different formats is very damaging. (With the exception of "lossless" TIFF format) HEIC is overhyped, I'll explain why… I'm an imaging professional. for a living: After analysis on my own part, I don't approve of HEIC format. I think Apple, shall we say, they have been misinformed to introduce HEIC as a standard over JPEG. It wrecks extreme highlight and shadow detail, leading to posterization and color casts. I've seen this on multiple examples. The file size saving is too minimal for this loss to be justified. Just because a format is old, (like JPEG or GIF), doesn't mean it has any inherent fault and needs to be replaced. Also saving on HD space these days is also a highly dubious motive. Driven by suppliers attempting to save money, not to improve the quality of users saved images.
