Why it's different

Other compressors upload your files. This one doesn't.

Most PDF compressors send your file to a server to process it. Your contracts, IDs and private scans end up somewhere you can't see. On-device compression skips that entirely.

Web / online compressors
  • Your file is uploaded to their server
  • Needs a connection, often a login
  • Copies may be kept or cached
PDF Compressor (this app)
  • Done entirely on your iPhone
  • The app requests no network access
  • No server copy to delete later
