How to Sign a PDF Without Adobe Acrobat

You don’t need Acrobat, Reader, or any download to sign a PDF. Do it right in your browser — sign, then download the finished file. No install, no account.

Sign a PDF — no Acrobat needed
  • Nothing to download or install
  • No account needed
  • Your file stays on your device

Why you don’t need Acrobat just to sign

Adobe Acrobat is built for editing, converting, and managing PDFs in every way — that’s a lot of software for a task that’s really just “put my name on this page.” Signing a PDF only needs two things: a way to open the file, and a way to place a mark on it. Both of those can happen entirely inside a browser tab.

A browser-based signing tool skips the download, skips the install, and skips any account setup for Acrobat or Adobe Reader. It works the same on a locked-down work laptop, a borrowed computer, or a phone — anywhere you can open a web page.

Frequently asked questions

Do I actually need Adobe Acrobat to sign a PDF?
No. Signing a PDF — adding your name, initials, or a drawn signature to a specific spot on the page — doesn’t require Acrobat’s full editing suite. A browser-based signing tool reads and writes the PDF directly, with no software to download or install.
Is a PDF I sign this way still legally valid?
For most everyday agreements, yes. A typed or drawn signature is a valid electronic signature under laws like the US ESIGN Act and UETA, the EU and UK’s eIDAS rules, and equivalents in many other countries — regardless of which application placed it on the page. This free tool creates a self-signed document without an audit trail, so it offers limited proof of who signed if a signature is ever disputed. Are electronic signatures legal?.
What if I don’t have any PDF software installed at all?
That’s fine — that’s the point. A browser-based tool needs nothing installed on your device. Open the page, drop in your PDF, sign it, and download the result. It works the same on a work laptop where you can’t install software, a shared computer, or a phone.
I need someone else to sign this document too. Can I do that here?
The free tool is for signing your own document. To send a document to someone else to sign — with a full audit trail and a tamper-evident seal on the finished file — create a free Evenseal account. See plans and pricing.
