Each guide answers one task with exact settings, the limits of our free tools, and when another kind of tool fits better.
Resize the GIF to 128 × 128 with the Discord preset, then cut colors and frames until it's under 256KB, Discord's limit for custom emoji.
Pick the GIF's background color, start tolerance at 30 (range 0 to 255) and download. A free color key clears flat backgrounds; edges stay hard.
Compress a GIF by starting at 64 colors, every 2nd frame and 75% scale, then raise whichever setting shows visible damage. Change one setting per run.
Add up to 60 same-size PNGs to a PNG to GIF tool in frame order, set one delay from 20 to 2000 ms (100 ms = 10 fps), pick a loop, then download the GIF.
Sign in, upload one photo and describe the motion: 10 free credits cover one 480p, 6-second clip on Grok Standard. Downloads need a paid plan or a credit pack.
