About this app

Sign a lease, a school form or a delivery authorization in under a minute, right from your phone. No printer, no scanner, no account.

HOW IT WORKS
1. Open a PDF, or a photo of a paper document.
2. Sign with your finger, or type your name and pick a handwriting style.
3. Drag the signature onto the line, save and send.

SIGN YOUR WAY
• Draw your signature in blue, black or green ink, with three pen sizes
• Or type it: three elegant handwriting styles ready to use
• Save up to 5 signatures and reuse them with one tap
• Repeat the same signature on several pages without redrawing it

COMPLETE THE DOCUMENT
• Add today's date in one tap
• Add text: your name in block letters, "Read and approved", "Accepted"
• Move and resize every item before applying it
• Multi-page documents with zoom

WORKS WITH YOUR APPS
• From WhatsApp, Gmail or Files: tap Share and pick Firma Documenti
• Sign JPG and PNG photos too: they are turned into PDFs
• Share the signed PDF or save a copy wherever you like

EVERYTHING STAYS ON YOUR PHONE
Your documents are never uploaded: the app works offline and the developer never sees your files. Find every signed document in the archive, with search and rename.

FREE, WITH A CHOICE
The app is free with unobtrusive ads. Remove them forever with a single purchase, no subscription.

Note: the app places an image of your handwritten signature on the PDF (simple electronic signature). It does not replace a qualified digital signature required for some official filings.
Sign PDFs and photos on your phone. Draw or type, then add a date and text.
