Everyday uses

  • Rent agreements and offer letters – sign and return in minutes.
  • Undertakings and declarations – common for admissions and HR.
  • Invoices and delivery challans – sign before sending to clients.
  • Society and school forms – sign without printing and scanning.

Good to know

The signature is added as an image on the page — the same as a scanned signature. Uploaded signature photos have their white background removed automatically.

This is a simple electronic signature, not a certificate-based digital signature (DSC) or Aadhaar eSign. Some legal and government documents require those; check with the receiver.

Private by design. Sign PDF works inside your browser. Your file is processed on your device and is not uploaded to our server.

Limits to know before you start

  • This is a simple electronic signature, not a certificate-based digital signature (DSC) or Aadhaar eSign.
  • The signature is an image on the page; the document is not locked against later edits.
  • Typed signatures use handwriting fonts made for English letters; other scripts use your device’s standard font.

If something goes wrong

The uploaded signature has a grey background. Photograph it again on plain white paper in good light, and crop tightly with Crop Image.

The signature is in the wrong place. Tap it to select it, then drag it. Drag the round handle to resize.

The tool asks for a password. The PDF is protected. Type the password you normally use to open it; it is used only in your browser. The new file is not locked.

Sign PDF – questions

How do I sign a PDF on my phone?

Open the PDF here, choose Draw and sign with your finger, then tap the page where it should go.

Can I upload a photo of my signature?

Yes. Sign on white paper, take a photo and upload it; the background is removed.

Can I sign multiple pages?

Yes. Place your signature on as many pages as you like, or select it and use “Copy selected item to every page”.

Is this legally valid?

It places a visible signature image. In India that is not one of the electronic signatures recognised under the IT Act, 2000 (those are a DSC or Aadhaar eSign). Many people accept it for informal documents; check with the receiver, and use a DSC or Aadhaar eSign where the law or the receiver requires one.
