GIF Compressor

Live

Free online GIF compressor — compress GIF files and reduce GIF file size with adjustable output settings, right in your browser.

Open tool

A smaller file is useful only if it still does the job. PDF and GIF compression have different tradeoffs: PDF tools can optimize structure and recompress embedded images, while GIF compression reduces dimensions, frame rate, or colors.

These tools process files locally and show the actual result size. A target is not a guarantee: an already optimized document or a long scan may not fit a strict upload limit. Keep your original and check the result before sharing.

Fit a PDF upload limit

Try a 100KB, 200KB, or 500KB target. The result clearly states whether the final PDF fits, including when it cannot get small enough.

Keep the detail you need

Use Keep quality for PDF image fidelity, or Balanced for a smaller everyday copy. Compare fine print and images before downloading.

Shrink an animated GIF

Reduce dimensions, frame rate, or colors for chat, forums, avatars, and CMS uploads.

What to check before converting

PDF target sizes use decimal units: 1 KB is 1,000 bytes. The final byte count determines whether the file fits.
Stronger image compression may reduce detail. Some PDFs are already too compact to shrink further.
For GIFs, start with width, then frame rate, then colors. Consider video when the destination supports it.
