Image File Formats - JPEG, GIF, PNG

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

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

Do an episode on MP3, OGG, WAV and FLAC

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

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

Jhon is like Linus's VSauce

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

1:13 Woah that sounds change in his voice

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 👍

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

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

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.

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

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

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.

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

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