Sign a PDF
Processed on this device. Nothing is uploaded.
Draw your signature — pick an ink colour and a pen style, from a fine liner to a marker — and tap the page to place it, or drag it into position. Change your mind on the colour after drawing it, resize it with two buttons, and choose where it goes: one page, or every page in the document. Press Sign and the file downloads straight from your browser, built and verified there, with your original untouched. No account, no upload, no watermark — it is genuinely the fastest way to get a signature onto a PDF or a contract.
The simplest way to sign a PDF or a contract, without printing anything
The old way to sign a document is still what a lot of people default to without thinking about it: print the PDF, sign it with a pen, scan it back in, and email the scan — often on a phone camera, at an angle, with a shadow across the signature. It works, but it is four steps and two pieces of hardware to accomplish something that takes ten seconds here: open the file, draw once, download.
That is the actual bar this tool is built to clear — not "another way to sign a PDF," but the easiest one available anywhere, digital or paper. Draw with a mouse, a finger, or a stylus; tap the page where the signature goes; download. No account to create first, no email verification step, no file size cap, and no watermark stamped across your signed contract because you didn't upgrade to a paid plan.
Built for contracts, not just one-off forms
A permission slip needs one signature. A contract usually needs your initials on every page and a full signature at the end — and doing that by hand, page by page, in a heavier PDF editor is exactly the kind of repetitive task worth automating. Choose "All pages" once and the same signature lands in the same spot on every page of the document, so initialing a twelve-page lease takes the same one action as signing a single-page form.
Electronic signature or digital signature — which one is this?
The two terms get used interchangeably, but they are not the same thing, and it is worth knowing the difference before you sign something that matters. An electronic signature is any electronic mark that shows intent to sign — typing your name, drawing it with a mouse, or clicking "I agree." That is what this tool creates: a real signature, drawn by you, placed onto the page. A digital signature is a narrower, technical term for a signature backed by a cryptographic certificate that a verifier can check against a trusted authority — the kind a bank or a government portal might require. This tool does not create that. If a form specifically demands a certificate-backed digital signature, this is not the right tool for it; for the very large majority of contracts, agreements, permission forms and everyday paperwork, an electronic signature is exactly what is expected.
Is an electronically signed PDF legally binding?
In the United States, the ESIGN Act (15 U.S.C. § 7001) and the UETA — adopted in some form by nearly every state — both establish that an electronic signature cannot be denied legal effect solely because it is electronic rather than handwritten on paper. Similar frameworks exist in most other countries (eIDAS in the EU, for instance). What actually matters legally is not the tool used to make the mark, but whether the signer intended to sign and the signature is genuinely attached to that document — which is exactly what drawing a signature and placing it on the page establishes. This is general information, not legal advice specific to your document or jurisdiction; for a contract with real stakes, it is worth confirming electronic signature is acceptable to the other party and appropriate for that specific document type.
Doing more than one thing?
The full editor puts every operation in one workspace with undo, so you are not exporting and re-opening between each step. Same engine, same privacy, still nothing uploaded.
Why this one does not upload your file
Almost every free sign a pdf tool works by sending your document to a server, doing the work there, and sending a result back. That is a cost decision rather than a privacy one — server time costs money, which is why those tools meter you, ask for an account, or cap your file size.
This one runs the same work in your browser using JavaScript, so your file never travels anywhere. There is no upload step, no queue, no account, and no page limit — and the page keeps working if you disconnect from the internet partway through.
You do not have to take that on trust. Open your browser's network tab and watch while you work, or read how it works.
