How to sign a PDF yourself — free, in your browser, no account
Need to sign a PDF and send it back? Do it free in your browser — no account, no printer, no app. Here's how, and when you need a full audit trail instead.
You've been emailed a PDF — a form, a release, a one-page agreement — with a line at the bottom that says *sign here*. You don't need to buy software for this, and you definitely don't need to print it. Here's how to sign a PDF yourself in about a minute, straight from your browser, without creating an account or installing anything.
The old way: print, sign, scan, pray
The reflex for a lot of people is still print → sign in pen → scan → email back. Every step is a small tax:
- Printing assumes you own a printer with ink, which fewer people do every year.
- Scanning means a scanner or a phone app, and a crooked, greyish photo of a page.
- Quality suffers — a scanned signature page usually looks worse than the original.
- Time — a two-minute task turns into a fifteen-minute errand.
There's a faster way that produces a cleaner file, and it's free.
Sign it in your browser instead
Signed has a free self-sign tool at /sign: open the page, drop in your PDF, and it renders right there in the browser. You place your signature, fill any blanks, and download the finished PDF — done. There's no account to create and nothing to install, and it works the same on a laptop or a phone. If you've ever fought a desktop PDF editor just to add one signature, this is the shortcut.
What you can drop onto the page
The self-sign tool covers everything a form or agreement usually asks of you:
- Signature — draw it or type it, placed exactly where the line is.
- Initials — for the per-page or per-clause boxes.
- Date — today's date, on the line that asks for it.
- Text — your name, address, or any blank you need to fill in.
- Checkbox — the acknowledgment boxes.
Then you flatten and download — the fields become part of the PDF, so it looks and prints identically for whoever receives it. The full reference for each field type is in Sending & signing.
Your file never leaves your device
Here's the part that matters for anything sensitive: the free self-sign tool runs entirely in your browser. Your PDF is never uploaded to a server — it's opened, signed, and saved locally on your own machine. That's a promise a lot of "free online sign" tools can't make, because they upload your file to sign it and then often wall the finished download behind a sign-up. For a tax form, a medical release, or anything with personal details on it, keeping the file on your device is the honest privacy default.
Is a self-signed PDF legally binding?
For most everyday documents, a signature you add electronically is valid under the US ESIGN Act and UETA — the same laws that make any e-signature count, explained in are electronic signatures legally binding?. What a simple self-signed PDF *doesn't* carry is proof — there's no built-in record of who signed, when, or from where. For a form you're filling in and returning, that's usually fine. For an agreement someone might later dispute, that proof is the whole point — and it's a different tool. (General information, not legal advice.)
When you need more than a self-signed PDF
Reach for the full send-and-sign flow — not the free self-sign tool — when any of these is true:
- Someone else has to sign too. A contract with a client, a lease with a tenant, an NDA with a counterparty — you need to route it to them and collect their signature.
- You need a record that holds up. The request flow builds a tamper-evident Certificate of Completion — each signer's email, timestamps, and IP, sealed against later edits (what's in it).
- You want to track it. Sent → viewed → signed → completed, with reminders for anyone who stalls.
The step-by-step for that flow is in how to send a document for electronic signature; if the other party is a tenant signing a lease, see how to get a lease signed online.
What it costs
Signing a PDF yourself on Signed is free forever, no account required — that's the whole point of the /sign tool. When you need to *send* documents for other people to sign, that's the paid product: one plan, $9.99 per seat per month, unlimited documents, month-to-month, no annual contract. A seat covers you, the sender; the people signing never need an account or a seat. The full breakdown is on pricing, and the case against paying enterprise rates for the same job is on the DocuSign comparison page.
