Suppose a 480-pixel reaction looks right in a chat preview, but the upload rejects it. The layout is fine. Check the file's bytes and the destination's limit before changing the width.

Here is one result from our GIF tool's release test. A four-frame GIF was 847,960 bytes. With a 250 KB target, the browser produced a 248,947-byte GIF that decoded successfully. That's about 71% fewer bytes for that file. A different image can land above the target, especially when it needs many colors or frames.

Try the same workflow on a file you can share:

  1. Keep the original and note its dimensions and size.
  2. In the Discord GIF compressor, choose a target that leaves a little room under the limit.
  3. Download the output. Compare the actual bytes and watch a complete loop.
  4. If it is too large, trim idle frames or reduce the palette. If the preview is too wide, open the GIF resizer and set the dimensions first.

It's easy to mistake the number in the target field for the size of the finished file. The downloaded bytes tell you whether it fits. And a file that fits can still be hard to read, so check the preview after every aggressive change.

I work on GifLoom. The tool runs in the browser, and you can reproduce the workflow with your own GIF.
