Sign a PDF on Your Phone Without Printing
Draw or place a signature on a PDF from your phone browser. Skip the print-sign-scan loop for offers, NDAs, and school forms.
Printing a contract just to scribble a name is wasted paper and time. A phone browser can open the PDF, capture a finger-drawn signature, and place it on the signature line so you can send the file back in minutes.
Draw once, reuse carefully
In Sign PDF, draw your signature with a finger or stylus, then place it on the page. Keep the stroke simple so it stays readable when the page is shrunk for email. Do not reuse a signature image that includes your entire ID card.
Place it on the right coordinates
Pinch-zoom to the signature block, drop the mark, and nudge it so it sits on the line. Save and open the download once to confirm it did not land on the wrong paragraph.
Lock or compress before you send
If the signed file contains personal data, Protect PDF adds a password. If the scan is huge, Compress PDF helps it clear mobile email limits.
Step-by-step
- Open Sign PDF on your phone and upload the file.
- Draw your signature and place it on the page.
- Download the signed PDF.
- Optional: password-protect or compress, then send.
FAQ
Is a drawn signature legally valid?
Many everyday agreements accept electronic signatures, but rules vary by country and document type. For high-stakes filings, confirm local requirements.
Do I need an app store install?
No. IzPDF runs in the mobile browser so you can sign without installing desktop software.
