Is this PDF signer really free?

Yes. 100% free forever — no trial, no premium tier, no per-signature charge, no daily quota. Sign as many PDFs as you want. Ad-supported so it stays free for everyone. Unlike Adobe Acrobat (which gates cryptographic signatures behind a $15/mo subscription), Smallpdf (2 signatures / day free), and iLovePDF (free tier limited) — we give you everything on the free tier.

Do I need an account?

No. No signup, no login, no email, no captcha, no credit card. Open the page, drop your PDF, sign, download.

Is my PDF uploaded to a server?

No. The entire signing happens locally in your browser using the Web Crypto API for RSA keypair generation and PKCS#7 / CMS packaging. Your PDF never leaves your device — there is no server-side copy because we don't have a server for your files.

Is my signature or private key sent anywhere?

No. Your signature image, drawing, or typed name stays in browser memory. If you upload a .p12 / .pfx certificate, it's parsed locally — never transmitted. The generated private key for self-signed certs lives in Web Crypto's non-extractable storage and is discarded when you close the tab.

What's the difference between an electronic signature and a digital signature?

An electronic signature is any visible mark placed on a document — a drawn scribble, a typed name, a photo of a handwritten signature. It looks like a signature but has no cryptographic proof. A digital signature is a cryptographic operation: the document's content is hashed (SHA-256), the hash is encrypted with your private key (RSA-2048), and the result is embedded in a PKCS#7 / CMS structure inside the PDF. Anyone can verify two things from that: (a) the document hasn't been modified since signing, and (b) it was signed by the holder of the corresponding private key. Most legal jurisdictions (EU eIDAS, US ESIGN, most of Asia) recognise digital signatures as legally equivalent to wet-ink signatures; electronic-only signatures sit on weaker footing. Our tool does both — visible AND cryptographic — in a single signing pass, which is what Adobe Acrobat Pro also does, but for free.

How do I sign a PDF for free?

Drop your PDF on the page above. The editor opens with the Certify modal pre-selected. Choose draw / type / upload for a visible signature, then click the page where it should go. Click Save — the PDF is cryptographically signed with your in-browser-generated certificate and downloads. Entirely free, entirely local, no signup. Most competitors gate either the crypto or the no-watermark output; we don't.

How do I add a signature to a PDF?

Same flow. Drop PDF, pick how to produce the signature (draw / type / upload a PNG or JPG of your signature), place it by clicking the page. Our visible signature renders at the exact pixel position you click, with the size you drag to, so it lines up with the signature line on contracts, NDAs, tax forms, etc.

Are PDF signatures legally binding?

In most jurisdictions, yes, with nuance. The EU's eIDAS regulation recognises three tiers: Simple Electronic Signature (SES — e.g. a typed name, accepted but weaker), Advanced Electronic Signature (AES — uniquely identifies the signer, our cryptographic output qualifies), and Qualified Electronic Signature (QES — requires a trust-service-provider-issued certificate, not produced by our tool). The US ESIGN Act (2000) and UETA treat most electronic signatures as legally equivalent to wet-ink. High-stakes contexts (notarised deeds, some courts) may require QES or physical signatures — consult a lawyer if the stakes warrant it. For everyday business use (contracts, NDAs, HR forms, vendor agreements), our cryptographic output is usually sufficient.

What is PKCS#7 / CMS?

PKCS#7 (Public Key Cryptography Standards #7), also known as CMS (Cryptographic Message Syntax), is the standard encoding for digitally signed data that every major PDF viewer understands. When you sign a PDF through our tool, we compute a SHA-256 hash of the document's byte range, encrypt the hash with your RSA-2048 private key, and package the result along with your certificate into a PKCS#7 structure. That blob is embedded inside the PDF's /Sig field. Adobe, Chrome, Edge, Foxit, and macOS Preview all read PKCS#7 signatures natively and show a verification badge — the exact same mechanism Adobe Acrobat Pro and DocuSign use.

Do the signed PDFs work in Adobe Acrobat?

Yes. Our PKCS#7 output is standards-compliant — we tested against Adobe Acrobat Reader DC, Adobe Acrobat Pro, Chrome's built-in PDF viewer, Edge, Firefox's PDF.js, macOS Preview, and Foxit Reader. All show a verification badge. For self-signed certificates (generated in-browser), Adobe shows yellow 'signer unknown' warning — this is the correct behaviour, because self-signed certs have no third-party trust anchor. To get a green badge, upload a .p12 from a trusted Certificate Authority (Digicert, Sectigo, GlobalSign, your organisation's internal PKI).

How do I sign a PDF with a .p12 / .pfx certificate?

In the Certify modal, click 'Use existing certificate'. Upload your .p12 or .pfx file, enter the password if it has one. The certificate is parsed locally — both the public and private key stay in browser memory and are used only for this signing pass. The signed PDF carries your real identity (issuer, subject, validity dates) which any verifier can check against the issuing CA's root store.

What if I just want a visible signature without the crypto?

Pick the 'Visible only' option in the Certify modal. You get a PDF with your drawn / typed / uploaded signature placed on the page — no cryptographic structure, no PKCS#7 embedding. This is equivalent to what iLovePDF and Smallpdf produce on their free tiers. It's legally weaker (just an electronic signature, not an advanced one) but fine for casual use where the other party doesn't need cryptographic proof.

Can multiple people sign the same PDF?

Yes, sequentially. Sign once and download. The recipient opens the signed PDF in our tool, drops it in, and signs again. PDF's byte-range mechanism supports any number of sequential signatures; each new signature covers a byte range that includes the previous signatures, producing a chain of verifiable signatures. (Concurrent multi-party signing — one PDF sent to five people at once — requires workflow software like DocuSign or Adobe Sign; we're a single-user tool, not a workflow orchestrator.)

Does it work offline?

Yes, once the page has loaded. The signing engine runs entirely in your browser — you can disconnect from the internet and keep signing. Great for sensitive documents (NDAs, medical releases, financial agreements) you'd rather process without any network connection active.

Can I sign a PDF on my phone?

Yes. Open the page on your phone's browser, tap Select PDF, tap Draw and trace your signature with your finger on the touchscreen, tap Save. Works on iPhone Safari, iPad, Android Chrome. Touch signing feels natural on iPad Pro with Apple Pencil — comparable to DocuSign's mobile experience but without the subscription.

Can I sign a password-protected PDF?

If the PDF is owner-locked (opens without a password), yes. If it requires a password to open, unlock it first with our /unlock-pdf tool, then sign. Our unlocker is also 100% local — the password never leaves your device.

What about timestamped signatures (RFC 3161 TSA)?

Timestamped signatures add a trusted-time-server stamp to prove WHEN a document was signed, independent of the signer's system clock. They require a network call to an external TSA (Time Stamping Authority) — which breaks our local-only promise. We don't ship timestamping today. If you need it for legal archival / long-term validation (LTV), our tool isn't the right fit; use Adobe Acrobat Pro or a commercial e-signing service. For 99% of personal and small-business signing, non-timestamped signatures plus the date field we embed are sufficient.

Is this the best free PDF signer?

For privacy-first workflows where you don't want your PDF, signature, or private key to touch a server, and where you want cryptographic signatures on the free tier (not gated behind Adobe's $15/mo), we think so — and we explicitly compare ourselves to Adobe, Smallpdf, iLovePDF, DocuSign, and Sejda below. For cross-party signing workflows (send to 5 people, track who signed), you need DocuSign or Adobe Sign. Pick the tradeoffs that match your actual use case.

About this tool: PDF Edit is built by a small independent team who were tired of PDF tools that required accounts, uploaded files to servers we didn't control, and gated cryptographic signing behind subscriptions. Everything here runs in your browser — your PDF, your signature drawing, and your private key stay on your device. The signing engine uses the Web Crypto API for RSA key generation and hashing, and produces PKCS#7 / CMS signatures that validate in every modern PDF viewer. Free forever, ad-supported.
