Hello, This question may not exactly be about scratch but it's about something thats very much like scratch but it's more advanced and/or has more stuff.
I'm about to work on acheivement icons for a game that I'm working on in a site that has “world” at the end of it (I don't know if it's mentionable due to it having live collabs) But I make my art on my phone and this is a school computer (My browser / operating system: Windows NT 10.0, Chrome 132.0.0.0, No Flash versions detected) so I don't know how to transfer stuff. So I'm wondering if you can save a sprite as a png and slap it on to the acheivement icon placeholder. If you can't, I will screenshot my sprite and take it to the Gimp thingy my school computer has.

Yes you can. It should work perfectly fine

I think it should work okay.

Update: Unfortunately, I've found out the site that ends with “world” dosen't support the “Sprite 3” file for acheivment Icons. So I decided to screenshot the icon I made on Scratch, erase the background with Gimp editor, and then convert the xcf file into a png. Thank you for your answers guys!

Yes. Go into the costumes tab, right-click on the costume in the left-hand sidebar, then click Export.

You don't need to do that- go to the costume and right-click/long tap on its icon, and then click “Export”. It will download as a portable network graphic file (PNG).

And no, most programs don't support .sb3 or .sprite3 files, but both are really renamed zipped folders- changing the file extension to .zip should allow you to uncompress it, and included in those files are all of the costumes and backdrops you have.
