The easiest way to sign documents.

SignDrop is a free Chrome extension that signs any PDF right in your browser. No uploads, no account, no subscriptions — your documents never leave your device.

Free forever · No sign-up · Works with any PDF

How it works

Signed in under a minute.

No account to create, no app to learn. If you can open a PDF, you can sign it.

  1. Open a PDF

    SignDrop spots PDFs in your open tabs — or drag in a file from your computer. Contracts, leases, forms, offer letters.

  2. Drop your signature

    Draw it, type it, or upload a photo of it. Create it once and reuse it on every document. Add dates and text too.

  3. Download & send

    The signed PDF saves straight to your device and your local library. Attach it to an email and you’re done.

Sign from your phone

No mouse scribbles. Sign with your finger.

Signatures drawn with a mouse look like a heart-rate monitor. SignDrop shows a QR code — scan it with your phone, draw your signature with your finger, and it lands on your desktop instantly.

  • Scan the QR code with your phone’s camera
  • Draw your signature on the phone screen
  • It appears in the extension, ready to place

Phone sessions are temporary by design: they expire after 5 minutes and are deleted the moment your signature arrives.

What you get

Everything you need to sign. Nothing you don’t.

Draw, type, or upload

Three ways to create your signature. Save it once, reuse it on every document.

Finds PDFs for you

SignDrop reads PDFs straight from your open tabs. Or upload a file from your computer.

Signed docs library

Every document you sign is kept on your device. Re-download or delete any time.

Dates, text & names

Fill the rest of the form too — drop in today’s date, your name, or any text.

Fast and lightweight

The popup opens instantly and everything runs locally — even on a slow connection.

Dark mode included

Matches your browser theme, easy on the eyes during late-night paperwork.

Security & privacy

Private by design.

Most e-signature tools upload your contracts to their cloud. SignDrop was built the opposite way: everything happens on your device.

Read the privacy policy
  • Your documents stay on your device

    PDFs are processed in your browser and stored in your local library. They are never uploaded to a server.

    Install and sign. SignDrop never asks who you are, and never collects personal information.

  • No tracking, no analytics

    No usage statistics, no cookies, no third-party trackers. What you sign is your business.

  • Phone sessions self-destruct

    Signing from your phone uses a temporary, unguessable session that expires in 5 minutes and is deleted the moment your signature arrives.

  • Minimal permissions

    SignDrop only asks for what it needs to spot PDFs in your tabs and store signatures locally — nothing more.

  • GDPR & CCPA compliant

    Easy when there’s nothing to collect. Read the full privacy policy — it’s short and in plain English.

FAQ

Questions, answered.

Is SignDrop really free?

Yes. SignDrop is free — unlimited documents, unlimited signatures, no trial, no watermarks, no “premium” tier hiding the useful parts.

Are my documents uploaded anywhere?

No. PDFs are opened, signed, and saved entirely in your browser. Documents and signatures are stored locally on your device and never sent to a server.

How does signing from my phone work?

When you create a signature, SignDrop can show a QR code. Scan it with your phone’s camera, draw your signature on the phone screen with your finger, and it appears in the extension on your desktop. The temporary session expires after 5 minutes and is deleted as soon as your signature arrives.

Are signatures made with SignDrop legally valid?

In most countries, laws such as the U.S. ESIGN Act and the EU eIDAS regulation recognize electronic signatures for the majority of everyday agreements — leases, offers, NDAs, forms. Some documents (like wills or notarized deeds) may require more; when in doubt, check the requirements for your document type.

Do I need an account?

No. There is nothing to sign up for. Install the extension and sign your first document right away.

What file types does SignDrop support?

PDF files — from your open tabs or uploaded from your computer. Signed documents are saved back as standard PDFs that open anywhere.

Is there a Mac or iPhone app?

Not yet — SignDrop is currently a Chrome extension, which also works in Edge, Brave, and other Chromium browsers. Mac and iPhone apps are on the way, with the same rule: free, and your documents stay on your device.

Sign your next document in seconds.

Free, private, and already in your browser.
