Sign the PDF lets you add your signature to any PDF document, right
on your phone.
- Works fully offline. Your documents never leave your device.
- Three ways to sign: draw with your finger, upload a photo of your
signature, or pick from your saved signatures.
- Place your signature anywhere on the page. Drag, resize, rotate
with on-screen handles.
- Apply the same signature to multiple pages at once.
- Saves directly to your Downloads folder as a fresh PDF — your
original stays untouched.
- Free. No watermark on signed pages. No mandatory account.
HOW IT WORKS
1. Open a PDF — pick one from your files, or tap "Share" inside any
PDF app and choose Sign the PDF.
2. Tap the + button. Draw your signature, upload an image, or choose
one you've saved before.
3. Drag it where you want. Pinch to zoom in for precise placement.
Use the corner handles to resize or rotate.
4. Tap Save. Your signed PDF lands in Downloads, ready to share or
email.
PRIVACY
Sign the PDF runs entirely on your phone. We do not upload your
documents anywhere. The only network calls the app makes are for
Google AdMob ads (which keep the app free). The app never reads,
copies, or transmits the contents of your PDFs.
