How to sign a PDF
- Open the PDF. It is read by your browser and never uploaded.
- Choose Signature, then draw it, type your name in a script style, or add a photo of your signature on paper.
- Click or tap the page where it goes. Drag to move it, use the corner handle to resize and the top handle to rotate.
- Add initials, the date, text or check marks the same way, and fill any form fields straight on the page.
- Choose Download signed PDF.
Three ways to make your signature
- Draw it with a mouse, trackpad, stylus or finger. Strokes get thinner when you move fast, like a pen, and the result is trimmed to the ink.
- Type your name and pick one of four handwriting styles. Your initials are filled in for you.
- Photo: sign on white paper, take a picture and add it. Shadows, paper texture and ruled lines are removed, and only the ink is kept, on a transparent background, so it sits on the page like real ink.
Black and blue ink are both available. Blue makes it obvious on a printout which copy carries the original signature.
What else you can add
Initials, today's date in the format you choose, free text anywhere on the page (any language, including Hindi, Urdu and Arabic), and check marks or crosses for tick boxes that are only printed on the page. Every item can be moved, resized, rotated, copied to every page, or deleted, and Ctrl+Z undoes.
If the PDF has real form fields, they are found automatically and you type straight into them. See fill a PDF online for how that works.
Why it runs in your browser
The documents people sign are usually the private ones: leases, offer letters, bank forms, medical consent. Most free signing sites upload them to a server and limit how many you can do before asking you to pay or sign up. Here the work happens on your computer or phone, so there is nothing to upload, store or limit.
Is a signature made here legally binding?
What this tool makes is a simple electronic signature: a picture of your signature placed on the page, the electronic version of signing a printout. It is not a certificate-based digital signature. There is no certificate, no cryptographic seal that shows whether the file was changed later, no identity check and no audit trail. Whether that is enough depends on the document, where you are, and what the person receiving it accepts.
United States
- The federal ESIGN Act says a signature or contract "may not be denied legal effect, validity, or enforceability solely because it is in electronic form" (15 U.S.C. §7001(a)). An electronic signature can be any "sound, symbol, or process" a person adopts with the intent to sign (§7006(5)).
- The Uniform Electronic Transactions Act (UETA §7) says the same at state level and has been adopted by 49 states and DC. New York has its own law with the same effect (State Technology Law §304).
- ESIGN does not cover wills and testamentary trusts, adoption, divorce and other family-law matters, court orders and filings, and certain notices such as foreclosure or eviction of a home, utility shut-off and insurance cancellation (§7003). Use ink, a notary or the court's own system for those.
- A simple signature proves little about who signed. If the other side may dispute it later, a signing service that verifies identity and keeps an audit trail is the safer choice.
India
- Under the Information Technology Act, 2000, an "electronic signature" means a technique listed in the Act's Second Schedule, such as Aadhaar-based eSign, or a digital signature made with a Digital Signature Certificate (sections 2(1)(ta), 3 and 3A). A pasted image of your handwritten signature is neither, so it does not carry the Act's legal recognition where a law requires a signature (section 5).
- The Act also says a contract is not unenforceable just because it was made electronically (section 10A). Whether a signed PDF is enough for everyday paperwork is up to whoever receives it. If a portal or official asks for a DSC or eSign, this tool is not that.
- The Act does not apply at all to wills, powers of attorney, trusts, contracts to sell immovable property, and negotiable instruments other than cheques (section 1(4) and the First Schedule).
In court, an electronic record is not refused just for being electronic, though proving it follows the evidence rules in theBharatiya Sakshya Adhiniyam, 2023(sections 61 and 63), and the burden of showing who signed is on the person relying on it.
This is general information, not legal advice. For anything high-stakes, ask a lawyer where you live.
After you sign
Uploading the signed copy to a portal with a size limit? Compress the PDF to a set KB, such as 200 KB or 1 MB, and check every page before you send it. Sending a signed document that also holds account numbers or an ID you don't want to share? Redact the PDF so those parts are removed, not just covered.
Questions people ask
Is my PDF uploaded anywhere?
No. The PDF is opened, signed and saved by your own browser. Nothing is sent to a server, so it works on confidential documents and keeps working if you go offline after the page loads.
Is it really free?
Yes. There is no account, no daily limit, no watermark and no trial. Sign as many PDFs as you like.
Is a PDF signed this way legally binding?
It is a simple electronic signature. In the US, the ESIGN Act and state UETA laws say a signature cannot be refused just because it is electronic, with exceptions such as wills and court papers. In India, a pasted signature image is not an IT Act electronic signature (that needs Aadhaar eSign or a Digital Signature Certificate). See the section on this page for details and sources.
Can I sign on my phone?
Yes. Draw your signature with your finger, tap the page to place it, and drag to move it. The download works in mobile Chrome and Safari.
Will my signature be saved?
Only if you tick "Remember on this device". It is then kept in this browser only, and you can delete it from the signature window at any time. Without that tick, nothing is kept after you close the page.
Can I sign every page or add initials to each page?
Yes. Place your initials once, select them, and choose "Every page" to copy them to the same spot on all pages.
Does it work with password-protected PDFs?
Yes. Enter the password and it is checked on your device. If a PDF is locked against editing, the signed copy is rebuilt from page images, and the tool tells you before you download.
