TIFF or JPEG

[Magi]

Was wandering what everyone's opinion was on TIFF vs JPEG and if is there a good TIFF viewer out there?

JPEG is usually lossy: there is a lossless JPEG format, but it isn’t widely supported. Although TIFF isn’t lossy, even compressed TIFF files can be quite large, and most web browsers won’t display images in TIFF format.

XnView MP is a good image viewer, supporting a wide range of formats. IrfanView is the image viewer that I generally use, but it’s only available on Windows.

Also, the common JPEG format does not support transparency so files in that format will always have a background color, even when there are otherwise empty parts of the image. Additionally, the JPEG format is suitable only for saving a single image, while the TIFF format can contain multiple tagged images.

JPEG vs. TIFF depends on what you want to do with them. I use both but obviously for different purposes.

I would say: Use TIFF for Storage/Archive of images as an alternative to the .afphoto format. They will preserve (almost) all of your layers but not any history (which .afphoto format will).

Use JPEG or PNG for output to web pages, most (but not all) printing (sending to a printer) or for posting images on forums like this. PNG offers transparency and also a 8-bit version suitable for graphics or screenshots of the affinity interface with relatively few colours. The 24-bit PNG offers full colour but is a lossless format so is typically bigger than a JPEG file.

That's what I do.
