Compress your files

Compress images directly, or crunch PDFs and other files into a smaller compressed package.

Uploaded files 0 files
MP3 and MP4 compression runs with FFmpeg directly in your browser. The first media compression may take a little longer while the compressor starts.

Your crunched files

Images are re-encoded in your browser. PDFs and other files are compressed into a downloadable .gz package. Large files are limited only by your device/browser memory.

Why CompressGecko?

A simple compressor built for people who just want smaller files.

♾️
No artificial limits

There is no site-enforced daily quota. Your practical limit is the memory and processing power of your own device.

🔐
Private by design

Image compression happens directly in the browser instead of sending your images to a conversion server.
