How to sign a PDF for free
- Open your PDF. No sign-up screen, no email.
- Make your signature by drawing or typing it, or from a photo.
- Place it, plus initials, the date or text if the document asks for them.
- Choose Download signed PDF. The file has no watermark and no added pages.
What "free" means here
- No limits. Many free signing sites cap you at a document or two a day, or a few a month, before asking you to subscribe. There is no cap here.
- No account. Nothing to sign up for and no email to hand over.
- No watermark. The output is your PDF, unchanged except for what you added.
- No upload. Your document is processed by your browser. We never receive it, so there is nothing for us to store, scan or delete.
When a free simple signature is enough, and when it is not
Everyday paperwork usually only needs your signature on the page: a rental application, a school or medical consent form, an NDA, an invoice approval, a job offer you are accepting. The person receiving it decides what they accept, and a signed PDF is a common ask.
Some documents need more. A will, a deed or a court filing usually has its own rules (often ink, witnesses or a notary). If the other side might dispute who signed, use a service that verifies identity and records an audit trail. And in India, government portals that ask for a DSC or Aadhaar eSign need exactly that; a signature image will not do. The section below has the details and sources.
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).
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 there a limit on how many PDFs I can sign for free?
No. There is no daily or monthly limit, because the signing happens on your device and costs us nothing per document.
Do I need to create an account or give an email?
No. Open the page, open the PDF, sign, download. Nothing asks who you are.
Is there a watermark on the signed PDF?
No. The downloaded PDF is your document with your signature and anything else you added, and nothing else.
Can I send the PDF to someone else to sign?
Not from here. This tool signs a PDF on your own device; it does not email documents or collect other people’s signatures. Download your signed copy and send it to the next person, who can sign it here too.
What is the catch?
Moxisync Labs builds free tools as a way to show what Moxisync, a web agency, can do. The tools are the marketing. Signing here has no limits and no paywall.
How is this different from a paid e-signature service?
Paid e-signature services can verify the signer’s identity, route documents to several people, and keep a tamper-evident audit trail. That matters for contracts that might be disputed. For a form or letter you simply need to sign and return, a simple signature like this one is often all that is asked for.
