Summary: * *JPEG*: tiny file size, lossy compression. Bad at sharp edges/curves. * *GIF*: lossless compression, animatable. Only 256 colours. * *PNG*: lossless compression, no compression artifacts, transparency. Larger file size. * *TIFF*: supports any colour palette and compression as it's a container format, popular among photographers. Very large file size. * *SVG*: scalable without any quality loss. File size depends on how complex the image is, rather than the amount of pixels. * *RAW*: raw, minimally processed data from camera. * *HEIF*: supports animation and is higher quality than JPEG and GIF. * *BMP*: stores each pixel individually. Supports transparency. Very large file size. Note: file sizes aren't always smaller or larger; some formats are optimised for certain types of images. For example, PNG is smallest if you use few different colours. Edit: updated with information from the replies.

I'd like to see videos about the different file formats for audio and video as well, or even different types of media or documents if possible.

"A RAW files isn't an actual picture, but it just contains the information to create one." I'm pretty sure that's true of all digital image formats.

Discovering png was one of the greatest things in my life

Do an episode on MP3, OGG, WAV and FLAC

audio changes around 1:16 it's nothing extreme, but it sounded weird

Please END JPG on logos, graphics or cliparts. It's just awful to see people using JPG-compressed logos all over the place.

I only use JPEG to deep fry images with ungodly amounts of compression

Jhon is like Linus's VSauce

Video format, codec, container video please! For example, mkv (container) x264 (video codec), h.264 (video format)... and of course the audio and subtitles side

My favorite image format is actually PNG for a few reasons: 1. It supports transparency, and that’s a great feature to have for me especially, since I’m a graphics designer for myself. 2. The quality of images PNG provides are actually very good! Unlike JPEGs which have those “JPEG Artifacts”, as I like to call them, when viewed up close, and it looks absolutely terrible! 3. PNGs don’t take up that much space. I mean, JPEGs do take up a lot less space than PNGs, but mostly due to the JPEG Compression Artifacts, but PNGs still don’t take up that much more space than JPEGs anyways, since you’ll be getting a much better quality image with just a general file size increase. And you’ll probably notice that I compared PNGs to JPEGs, and in case you haven’t figured it out yet, I despise JPEGs for the reasons I stated above. Additionally, I’ll use TIFF images exclusively for Desktop Pictures & Wallpapers.

1:13 Woah that sounds change in his voice

Definitely an episode for MOV, MP4, M4A and such formats.

Great Video. Can you guys do "Audio Formats" next? Thank you!

It's been a solid few months since I watched a Techquickie video. Quality is noticeably improved. Great work Jon and editors keep it up 👍

This was crazy helpful. I'll be looking for the audio and video versions next

The blue dot that floats when the guy talks is bothering me

Any one else notice a blue pixel on his chest most of the video? Would that be a dead pixel? Seems a bit large for one.

Looking forward to hear about those audio formats!

To be honest I'd love to see more photo formats. This was a very interesting episode.

it's pronounced gif

PNG Masterace !!!

This went over my head. I need to watch it again

Great video with best explanations I have seen in a very concise timeframe. Well done!

John did a great job in this video, don't get the negative comments about that. On a completely different note, he reminds a lot of Michael Swaim (from After Hours) in this video for some reason - maybe it's the facial hair (not used to seeing him with it).

GIF's use indexed colours or palette, meaning a GIF can only have up to 256 colours but you can chose what colours to have in the palette from 24-bit RGB color space. Animated GIF's can have different pallete for each frame. Also GIFs can have one color defined as a transparency. but making it a pixely edged transparency. PNG's can have a fourth layer of color witch is aplha (or RGBA), giving more smoother transparency edges. PNG's can be smaller than JPEG's if the image has lot of same color surfaces. Company logos, witch are in two colors can be much smaller filesize and better in quality when saved in PNG and larger and with artifacts if in JPEG's. Canon new cameras have a RAW format with Double Pixel data (DP) witch gives new option to make small focus adjustments after the photo is taken.

Yes, we want more videos like this !!! Keep up the good work guys !!

RAW images are amazing, editing them is so much helpful, then converting them to PNG or JPEG help.

Yes! More videos like this, please. I'm a self-taught/still learning web dev and graphic designer and clear and concise information about all of the things you could cover is really lacking on the internet. It's there, but it's from tons of different sources, often times they're long articles that take while to read, blah blah blah. You should definitely do an audio formats video and probably not even stop there.

Colour spaces explained!!

Definitely do more videos like this, this is crazy helpful.

Def enjoyed this video and made it much easier to understand. I've always had a fascination towards all file extensions be it very specific ones, branded / company owned ones, and even obsolete ones, An idea?: start a mini series that go over ALL the file extensions that have ever existed in vids with the same style and manner you did here, there pros, cons, how they came about, there demise, room for improvements, and future potential replacers, that would be a really cool lil mini series you guys can start. I think

I like John. You can honestly do whatever you want I came here for the information.

*YES!* More please. Typically it's difficult to find a quick, fun fact YoutTube video which teaches the view of digital file formats and how they came to be -- very odd given that we all use computers and mobile devices to view content on KZfaq. There are so many different file types that I think this channel could again -- as has always -- exceeded my expectations. I look forward to more of these types of videos in the future! Thanks.

Clear, precise and straight to the point. I love it!

I still use BMP for certain kinds of editing like making glitch art, as it allows pretty awesome techniques you can't use in compressed formats.

1:15 when the bass drops

Really great video John

The way you explain makes it seem so easy! It really helped me! Thank you!

TIFF isn't necessarily an image format on itself; it's a container format, more meant to be some sort of album or bookcase to store images in. Yes, multiple. TIFF supports multiple images stored in a single file. Each image gets its own little data header that tells the program reading it what image format is used, what size it is and where to find the next header in the file. This also means that for single images TIFF will always be a larger file than its original format, but it offers great flexibility as each image can be in a different format and size.

This was soooooo understandable.

0:04 WTF!!! I searched the whole comments section!! No one noticed Linus's face there?! He looks better this way tho.

0:11 That BAFFLE bursted my ears ps. Thanks for these informative contents!

One of the best informational videos out there on this topic.

BLUE DOT!!!! what is it? Is it on purpose or an issue with the RED cameras?

PNG - Best general purpose format. Lossless compression, so good image quality for photos, text, graphics etc. JPEG - Bullshit. Should only be used when nothing matters. Doesn't work at all for text or graphics due to lossy compression. SVG - Good for graphics. Scaleable, so no limited resolutions. Doesn't work for photos. GIF - Outdated. Completely replaced by PNG. Shouldn't be used anymore due to limited resolution and colors. BMP - Old, but very simple. PNG is superior for general use, but BMP is marvelous for integration into custom programs. TIFF - Can contain lots of different formats. Don't use it unless you know what you are doing. If you do know it is great for keeping image quality, specifically higher than 8bit per color channel (R,G,B). Supports different color spaces, thus very useful for professional printing (CMYK). RAW - Best for editing. Not useful for any other purpose.

Made it clearer for me I until now after watching this video I was unsure about the different file formats and what they had in common

Really useful, thanks a ton guys. All these videos are incredibly informational.

Was this the guy that got fired?

JPEG: cuts out useless info to save space Also JPEG: saves your location for others to stalk you

I would love more videos on different file types!

This video was awesome! I'm so better informed now! They did not even explain these things so well in art school. More please.

0:08 is actually a pretty touching story.

Mpeg , MP4 , AVI , WAV ,MP3 , MIDI and many others files here we come.....

As a matter of fact I was wondering last week what the differences are :-) Yes, please make one about video formats.

Wow - so clearly explained. Thank you.

It's not that I dislike Linus or Luke, I really don't. I just really like John! Keep it up John. 4moreYears!

1:13 that bass drop, dang. 🤣

i love these tech videos

OMG, thank you!!! This video's helped me a lot.

Very helpful. 8.5/10

More file formats!!!

Thanks to give your knowledge

A _video_ on *_video_** formats* would be great. Also, *color spaces* explained. *We* want that.

5:19, i would like to know more about file types.

I usually save my photos as TIFFs so I can re-edit the photo without saving it as PSD.

ys. I would like more episodes. I always wonderd which format is better and this video solved it. thanks

I liked this video very much. Although I thought I knew everything about file formats you can always learn a thing or two.

Now i know, this is where I always struggle is, when saving a photo

I love your videos. You talk like an actual person and your voice is calming and not fatiguing like Linus'

Wow that is so much helpful information, thank you so much.

Since you used BMP is an example; i would have elaborated a bit more about that file format; since it still is really important in the printing sector.

WHAT DID YOU DO TO TO LUKE?!

This just popped up in my recommendations. Where is this guy? lol haven't seen him in a while.

Very helpful thank you!

Keep um coming this is so useful for content creation

Great video!!

linus with make-up what a change. 1st?

@linus i am sorry to even dream of getting a second or two of your attention... but.. seriously... this was really useful to a lot of people. personally, i knew most of it or at least the bits that i needed/wanted to. but... this, this is useful to a lot of people and will be re-watched once in a while by the same people, that needed info on specific issues. this sort of material can and will be a milk cow, considering the effort put in, beating the ltt main channel. because, this is info people will be coming back to to revise. personally, been fiddling with raw files for years... so this sort of info is not anything new to me and i think i might drop an angle on some statements.. but... without drifting off - this was a GOOD bit. think this through: 4 years, an under 7 minutes video with no hardware involved, except a dude editing it. (yes, editing costs too, but nowhere near to what you spend on bigger vids). SOME of your vids are already used in college/uni education as examples... why not monopolizing it, while at it? simples.. vgahdmidP style videos are useful... but they are scarce and hard to find. make a channel literally meant to explain all the basics. get them console peasants to actually understand, what are they arguing about, the next time they try defending a console. educate the peasants!

that was a good informative video. thank you

I love tunnel bear yaayyy~ also, I love Nick !! NVB!!

Gifs also supports transparency as far as I’m aware.

What an awesome video ! For years...I never knew ...Thanks !

id love to see more like this :)

"Hawtdawg!"

Linus got tanned? I almost didn't recognize him

Thank you! Very enlightening!

good concise explanations

That dead blue pixel on his jacket is beginning to bother me...

Lossy compression is for plebs, png master race

This channel is great... even when I'm already familiar with the topic I still check it out just to support LMG

Deffently more File Formats like this one and audio

I thought for a second they hired someone new.

needs more JPEG

I think I love you! Best explanation yet!

this is sooooo useful. thanks for putting up useful content

" *T U N N E L B E A R V P N !* "

Audio please, like if you want it too

I love your videos keep them Coming

I thought Raw format was the default file format of a given image editor (like PSD is for Photoshop). This video cleared up that misconception.
