How to export an image or raster layer?

[kjs]

I have an affinity document and I need export a layer or two and preserve all the quality possible. Is there a way to do that? To export a layer to a tiff, png, gif, or jpg.

A tiff will export at maximum quality at 8-bit or 16-bit, and can include layers.

A 24-bit png will export at 8 bits per channel at maximum quality for 8 bits.

An 8-bit png or a gif will only export up to 256 colours. Fine for diagrams, but not photos.

A jpeg will lose some quality depending on the degree of compression. It is better with photos than with diagrams. Can be 8-bit or 16-bit.

If you have a specific layer (or layers) you want to export, and others you don't, you can hide the ones you don't want in the Layers panel, then use File > Export.... Only the visible layers will be exported.

Edit: If you want to maintain them as editable layers, you would need to use TIFF. But they'll be layers only if you reopen the TIFF file in an Affinity application.
