Fit the GIF to where you post it

ChatGPT is rolling out GIF creation from prompts and still images. If it is available in your account, you can edit a GIF created in that chat and adjust its playback speed. ChatGPT does not currently edit animated GIFs you upload. What it gives you is a finished file, and that file still has to fit wherever you post it. A Discord emoji must be 256KB or smaller and a sticker 512KB at 320×320 px; many forums, email signatures and CMS uploads have their own limits. Drop the downloaded GIF here, type the target size and compress. If one pass is not enough, the related tools below crop it to a square, cut the clip shorter, drop frames or turn a plain background transparent, all without sending the file anywhere.

Choosing your settings

Resize before you reduce colors. A large GIF shown at emoji or chat size is scaled down on screen anyway, so lowering the dimensions saves the most bytes with the least visible loss. Keep the frame count for smooth motion and only cut frames if the size target still fails. For a sticker or emoji, the Discord pages below set the exact square for you.

If the result needs another pass

If the result is still above the target, trim the start or end of the loop, reduce frames, or lower the canvas size, then compress again. A target that cannot be reached is reported as failed rather than labelled as a success. If ChatGPT gave you a PNG or WebP instead of a GIF, use the GIF maker or WebP to GIF converter first.

GIF timing note: missing, 0 ms and 10 ms frame delays are read as 100 ms. Other supported delays are retained unless the task changes timing or the frame sequence. Re-encoded animation may therefore differ from a viewer that handles unusually short delays differently.

Good to know

Can ChatGPT make GIFs?

GIF creation is rolling out in ChatGPT. If available in your account, you can animate a prompt or still image, then download the GIF and compress it here. ChatGPT can edit GIFs it creates, but not animated GIFs you upload.

Why is my ChatGPT GIF too big for Discord?

Discord limits custom emoji to 256KB and stickers to 512KB, which is far smaller than most full-size animated GIFs. Shrink the dimensions first, then compress to the target; the Discord GIF compressor starts at the emoji limit.

Can I make a ChatGPT GIF transparent?

If the GIF has a flat, single-color background, yes: open it in Make GIF Transparent and click the background color. Busy or gradient backgrounds need to be regenerated with a plain background first.

Will compressing change the animation?

The output keeps the original loop setting and normal frame delays. Missing, 0 ms and 10 ms delays are read as 100 ms, so unusually fast GIFs may slow down. If you allow frame reduction, discarded frames’ decoded delays are added to the retained frames.

Is my GIF uploaded?

No. Everything runs in your browser and the file never leaves your device. GIFBloom is an independent tool and is not affiliated with OpenAI.
