Compress Files
Shrink files that are too big to email, upload or store. Compress photos to a target size, reduce PNG colours, slim down scanned PDFs, lower MP3 bitrates, resample WAV recordings and optimise GIFs. Each tool shows the size before and after and tells you if a file is already as small as it will get. Every compressor is free, with no file limit and no watermark.
Files never leave your device.

Questions
Are the compressors free?
Yes. They are free to use, with no sign-up, no watermark and no daily limit.
Do I need to install anything?
No. Every tool works on the website, so there’s nothing to download or install.
Do they work on a phone?
Yes. They work in current mobile browsers on iPhone and Android, as well as on desktop. Very large files may be slow on phones because of memory limits.
