With MacOS Catalina around the corner, I’m preparing to move from Photoshop CS5 to Affinity Photo, for which I bought a license some time ago.
When I prepare a .png for my website, I’m finding that .pngs exported from AP are bigger than their equivalents from Photoshop (eg 366 KB vs 330 KB). Most of my work is in greyscale and I’ve configured AP’s png export options like this:
Pixel format: Grayscale 8-bit
Resampler: Bilinear
Matte: None
ICC profile: Generic Gray Profile
Embed ICC Profile: unticked
Palettised: unticked
Embed metadata: unticked
Why are AP’s file sizes larger than Photoshop’s, and is there a way of configuring AP to export smaller .pngs?
I'd really appreciate some help with this. Thanks in advance.
