How to Sign a PDF Online for Free (Step by Step)
Printing a form just to sign it and scan it again is a waste of an afternoon. This guide shows how to draw, type or upload your signature and place it on a PDF in your browser, and is clear about what that signature is, and is not.
What kind of signature is this?
There are three different things people mean by “signing a PDF”, and they are not interchangeable.
- A typed name or visible mark. Your name appears on the page in a handwriting-style font. Our Sign PDF tool can do this.
- A drawn or image signature. Your handwritten signature, drawn with a finger or mouse or photographed on paper, is placed on the page. Our tool does this too.
- A digital (cryptographic) signature. A certificate-based signature, such as a DSC or Aadhaar eSign, that proves who signed and shows if anything changed afterwards. Our tool does not do this.
So what our tool adds is a simple electronic signature: a visible mark on the page. Whether that is good enough depends entirely on the document and on who receives it.
When a simple signature is usually fine
For many everyday, low-risk situations a visible typed name is accepted: acknowledging a school form, confirming that you have read a policy, returning an internal HR form, signing a note to a landlord, or approving a quote by email. The recipient mainly wants to see that you agreed and who you are, and a drawn or uploaded signature is often accepted where a typed one might look too casual.
When you should check first
Some documents call for more. Loan agreements, property documents, government applications and notarised papers often require a handwritten signature, a particular type of e-signature, or an official e-sign service. Rules differ by country and by organisation, so ask the receiver which they accept before you rely on a simple signature. If you are unsure, it costs one short message to check.
Step by step: sign a PDF
- Open Sign PDF and choose your file.
- Create your signature: Draw it with your finger, mouse or stylus, Type your name and pick a handwriting style, or Upload a photo of your signature on white paper. Press Use this signature.
- Tap the page where the signature should go. Drag it to move it and drag the round handle to make it bigger or smaller.
- Add a Date or a line of Text next to it if the form asks for one.
- Press Sign & download. The signed copy downloads with -signed added to the file name.
- Open the result and confirm that the signature sits on the signature line.
Choosing the page and position
Contracts and letters usually end with a signature block, so most people sign on the last page. Move between pages, tap the spot on the signature line, then fine-tune by dragging. Forms that need your initials on every page are quicker with Copy selected item to every page: place it once, select it, and it is copied to the same spot on all pages. Check the pages afterwards, because a spot that suits one page may cover text on another.
Limits you should know
- Not a digital signature. There is no certificate and the document is not locked against later edits.
- No DSC or Aadhaar eSign. Documents that legally require those need a dedicated service.
- It is a picture. Anyone who receives the file can see your signature and could copy it, just as with a scanned signature.
- Typed styles are handwriting fonts. They look best with names written in English letters; names in other scripts are shown in your device’s standard font for that script.
Worked example: returning a rental agreement
A tenant receives a 6-page rental agreement as a PDF. The owner has asked for a signed copy by email and is happy with an electronic signature. The tenant opens Sign PDF on their phone, draws their signature with a finger, goes to the last page and taps just above the tenant line, then adds the date next to it with the Date button. They open the signed copy, see that everything sits on the line, and email it. Had the owner asked for a wet signature, the tenant would have printed, signed by hand and photographed the pages, then used JPG to PDF to turn the photographs into one PDF.
Good habits when signing documents
- Read the document before you sign. A signature is easy to add and hard to take back.
- Sign a copy, not your only original. The tool creates a new file, but keep the unsigned original separately.
- Add a date. If the document has no date field, use the Date button to place today’s date next to your signature.
- Do not share a PDF with your signature on it publicly. A visible signature on a public file can be copied.
- For sensitive pages elsewhere in the document, redact private details with Redact PDF before you send it.
After signing
If you are also sending supporting documents, join everything into one file with Merge PDF. If the signed PDF needs page numbers, add them with Add page numbers before you sign so the numbers do not overlap the signature. To stop casual edits, you can also lock the signed copy with a password using Protect PDF.
Troubleshooting
An uploaded signature has a grey background. The tool removes a white paper background automatically. If some grey remains, photograph the signature again in good light on plain white paper, and crop tightly around it with Crop image first.
The signature is in the wrong place. Drag it to the right spot. Tap it first to select it if it does not move.
The signature looks too small or too large. Drag the round handle at its corner to resize it.
The drawn signature looks shaky. Draw a little larger and slower; it is scaled down when you place it, which smooths small wobbles.
Signature terms that often get confused
| Term | Meaning |
|---|---|
| Typed signature | Your name on the page in a signature-like style. Our tool can add this. |
| Drawn, scanned or image signature | A picture of your handwritten signature placed on the page. Our tool can add this too. |
| Electronic signature (e-signature) | A broad legal term for any electronic way of showing agreement. What counts depends on the law and the document. |
| Digital signature | A certificate-based signature (such as a DSC or Aadhaar eSign) that identifies the signer and detects later changes. Our tool does not add this. |
When someone asks you to "e-sign" a document, ask which of these they mean.
Frequently asked questions
Is this signature legally binding?
It places a visible signature image. It is not a certificate-based digital signature, and in India it is not one of the electronic signatures recognised under the IT Act, 2000 (a DSC or Aadhaar eSign). Many receivers accept it for informal documents; whether it is enough depends on the document, the receiver and the law where you are. This is not legal advice.
Can I draw my signature or upload an image?
Yes. Draw with your finger, mouse or stylus, type your name in a handwriting style, or upload a photo of your signature; a white paper background is removed automatically.
Can I sign every page?
Yes. Place your signature or initials once, select it, and use Copy selected item to every page.
Does signing change my original file?
No. A new copy with -signed added to the name is created and your original is unchanged.
