You can upload and compress up to 20 files simultaneously. All compressed files are downloaded as a single ZIP archive.

Yes. The file compressor is fully mobile-optimized and works in Safari on iOS and Chrome on Android without any app installation.

Question 5

Does the tool support PDF compression?
