Why your files stay on your device
Nothing is uploaded
Most online PDF sites send your file to their servers. PDFMoss does the work inside your browser, so there is nothing to intercept, store or leak.
No limits on uses
There are no daily caps because there are no servers doing the work. Use any tool as often as you like.
Works on your phone
Every tool works on iPhone and Android: pick photos from your gallery and sign with your finger.
Original quality, works offline
Pages and images keep their quality, and once you install the app the tools work without an internet connection.
