Compress a GIF to 500 KB

A short reaction GIF saved from a video is often several MB. To reach 500 KB it is compressed and usually made smaller in pixels, and it stays a GIF that plays at its own speed.

Getting a GIF under 500 KB

500 KB is a tight limit for a GIF, because a GIF stores every frame as its own picture. A two-second loop at a few hundred pixels wide can fit; a long clip at full size cannot.

After a lossless cleanup we try lossy compression at full size, then fewer colours together with fewer pixels. Only if that is still too big are frames dropped, and the frames that stay are held longer, so it plays at the same speed. The result says if frames were dropped.

Tips

  • Trim the GIF to the part that loops before you upload it. Fewer frames is the biggest saving there is.
  • Small GIFs with flat colours, like stickers and pixel art, fit far more easily than clips cut from video.
  • If the result is too small in pixels for you, a shorter clip will fit at a larger size.

How it works

  1. 1

    Drop your file

    A PDF or an image. It goes over an encrypted connection and nowhere else.

  2. 2

    Pick your limit

    Choose the size the form asks for. We start with a cleanup that changes nothing you can see.

  3. 3

    Download it

    If it needs more, we find the gentlest quality setting that still fits, and delete everything soon after.

Questions

Is it free?

Yes. There is no sign-up and no watermark.

What happens to my file?

It is processed on our server and deleted automatically: the original 5 minutes after the run finishes, the compressed file after 10. A file you upload but never compress is deleted within 30 minutes. You can also delete everything right away with Delete now.

Will it look worse?

We try a lossless cleanup first, which does not change how the file looks. Only if that is not enough do we lower image quality, and we pick the gentlest setting that still fits your size.

What if my file cannot get that small?

You get the smallest version we could make and a clear note saying so, instead of a file that silently misses the limit.

Why does the size page aim a little under its limit?

Some sites count a kilobyte as 1000 bytes and others as 1024. We aim under the stricter one, so a 200 KB page aims for 200,000 bytes and the file passes either way.
