Compress GIF

Frames optimised against each other and a lossy pass: half the bytes, same loop.

More free conversions, where you upload. The Fylane extension does the same work inside any upload form, on its own free share every day.About the extension

How to compress GIF

  1. Drop the GIF.
  2. Pick how hard to compress.
  3. Press Compress and download.

What happens to your file

gifsicle rewrites the animation: each frame stores only what changed from the one before, a lossy pass lets nearly-identical pixels be stored as identical (that is where most of the bytes go), and the palette is cut if you asked. Timing, looping and transparency stay as they were. The report says the bytes before and after.

A GIF that is already optimised shrinks little — that is the honest answer, and the numbers say so.

Questions

Will it look worse?

Light is hard to see; strong shows as slight banding in gradients. Flat cartoons and screen recordings survive strong well; photographs less so.

Still too big?

Resize GIF to a narrower width, or GIF to MP4 — a video is a tenth of the size.

Do this in code

curl -X POST https://api.fylane.dev/v1/jobs \
  -H "Authorization: Bearer $FYLANE_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "file_id": "<file id>",
    "operation": "image.gif-optimize",
    "options": {
      "lossy": 80,
      "colors": 256
    }
  }'

The same operation, image.gif-optimize — An animated GIF made smaller without leaving the format: frames optimised, a lossy pass, fewer colours, a narrower width. Upload first with the quickstart; every option is on the operations page. 500 free credits a month, then $5 per thousand.
