Compress PDF

Reduce the size of heavy PDF files, such as scans and photo documents, so you can email or upload them.

How it works

Each page is redrawn as an optimised image, which works best for scans and photos. Text in the compressed file can no longer be selected, so keep your original. Everything happens on your device.
