About

Convert a logo (SVG or PNG) into a ≤256px PNG suitable for upload as a Slack custom emoji (slack.com/customize/emoji or slackmojis.com). Outside-the-logo stays transparent; if the logo has a central circle/square with transparent cutouts inside, those cutouts get a white fill so they don't disappear on dark themes. Use when the user says "make a slack emoji from X", "extract logo X as slack emoji", "<=256 png for slack", etc.

Use cases: design, productivity
