	GIF	PNG	JPEG	TIFF
What?	Graphics Interchange Format. A bitmap image format - lossless	Portable Network Graphics. A raster graphics file format. Supports lossless data compression.	Joint Photographic Experts Group. Uses a lossy encoding method specific to photographic image data.	A tagged image file format. incorporates an extremely wide range of options. same compression algorithm as used in GIF
Why?	GIF's are easy to use and share. Animated unlike static photo - low data	PNGs are easy to use and came about after a data compression algorithm was used in a GIF.	JPEGs are mostly used for photography and are comparable to PNGs	TIFFs are mostly used for generic format for interchange between image editing apps.
How?	Used to send/convey messages. Quick. Low data and is mostly used on social media.	PNGs are used as a single file format as images. low data and mostly used around social media and graphics for websites.	JPEGs are a near lossless image format and has a standard set of test images.	Used format interchange between apps and so arent easily used anywhere other than between applications for photo editing.
Example	GIFs are inferior to other files such as PNG. They're used in websites - logos and brands.	PNGs are used as graphics for websites.	JPEGs are used for photography, backgrounds and features for sites. They are comparable to PNGs	TIFFs are used between apps for photo editing.
Pro's	Compression - small sizes - easy to share. 256 color palette. lossless compression. Widely supported. Supports alpha channels. Has multiple frames.	Uses lossless compression. Suitable for icons. Replacement of GIF. Has alpha channel transparency.	JPEGs generally perform better than PNGs and the file sizes and resolutions are directly comparable to PNGs	TIFFs support both types of compression from GIFs and PNGs and so overall are better. No data is lost throughout the process of scanning or compression. Can be used with most computer software. 16 Bit capability. Helps prevent posterization.
Con's	Level of quality in file goes to a certain size. Low maximum color depth.Oldest format.	Bigger file size than JPG. Has a big generated file size.	Although JPEGs generally perform better than PNGs on images, some images that are PNGs are substantially better on color depth. JPEGs lose quality upon compression.	Images take up a lot of space on your drive. Difficult and impossible to send in emails or any other sharing site.
Assess	In my opinion GIFs are easy to use and display a quick/short message on social media.	In my opinion PNGs are better than GIFs as the quality and color depth is higher.	In my opinion PNGs are better than JPEGs naturally due to perfoming better, however the ability that JPEGs have to display detail as a RGB file is good.	In my opinion PNGs and GIFs are better than TIFFs because of the qualities it has, while TIFFs dont have many cons, they take up a lot of space and cant really be used anywhere other than image editing apps, even then isnt always compatible with some.
Compare	PNGs however may  be a more advanced type than GIF as an alternative because compression is better and more features. GIFs are an RGB file format and so alpha/transparency is not part of it. Whereas a PNG is a RGBA file format. GIFS have low resolution but low data, whereas a PNG has high resolution, low data and is mostly used. GIFs are no longer industry standard.	PNGs could be better than JPGs because JPGs do not support the transparency alpha channel and is only a RGB file. JPGs are not suitable for icons or graphics and it generates a bigger file size for lower resolution images. However JPGs are better than PNGs because they're high details and quality pictures.	PNGs are better than JPEGs as compression doesnt effect the quality or resolution. However, PNGs arent able to be printed and JPEGs are.	PNGs and JPGs are overall better than TIFFs because they are lower datafile types thatn TIFFs, TIFFs arent easily used like GIFs and PNGs are.
Discriminate	PNGs may be better than GIFS if you're looking for high resolution and transparency. However GIFs are better because PNG doesn't support animation at all without MNG	JPGs in some cases are better than PNGs if you're looking for high resolution without the alpha channel.	If you're looking to print a picture, JPEGs are better as the CYMK will affect PNGs upon printing.	PNGs are better if you're looking for a file which is low data and can be used across all apps and devices. Same with GIFs. if you're looking for high quality images to edit on certain apps, TIFFs are good.
