Can't find this anywhere, tried the popular online converters.

How do I easily convert .ase or .aco to .png online?

I assumed you had enough Stack rep to understand how Stack works. You've basically just edited the question rather than marking my answer as correct. – Scott Apr 18 at 5:33

ase and aco files are not images. They are application code of color definitions within Adobe applications.

There may be a way to convert them directly to images, but I think that may be unlikely since the ase/aco formats are proprietary.

There are some online tools to display the colors. Such as ...

You could then take a screenshot to get a PNG.

I also found this: https://www.reaconverter.com/convert/ase_to_png.html for ASE 2 PNG, but it requires the download of software. I don't, in any way, vouch for this software. There are additional software downloads out there and a simple internet search will present them.

These URLs were merely cursory finds via an internet search. There may be better tools out there. I have no affiliation with either link.

  • NOTE: This one works for converting .ase https://carl.camera/sandbox/aseconvert/ … but this one does NOT work: https://aco-viewer.appspot.com because it adds additional colors and gray borders which mess up your screenshot (your palette would contain additional unintended color) – Rowe Morehouse Apr 18 at 20:04
