Draw, type, or upload
Three ways to create your signature. Save it once, reuse it on every document.
The easiest way to sign documents.
SignDrop is a free Chrome extension that signs any PDF, Word document, or photo of a form right in your browser. No uploads, no account, no subscriptions — your documents never leave your device.

Signature
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.
-
Open a document
SignDrop spots PDFs in your open tabs — or drag in a PDF, Word document (.docx), or a photo of a form. Contracts, leases, scans, offer letters.
-
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.
-
Download & send
The signed document saves to your device and your local library. Download it as a PDF, a JPG or PNG image, or a still-editable signed Word file (.docx). Attach 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.
PDF, Word & photos
Reads PDFs straight from your open tabs — and signs Word documents (.docx), photos, and scans (PNG, JPG, WebP, HEIC) too.
Download in any format
Signed docs are kept on your device. Download as PDF, JPG, or PNG — and Word uploads come back as a signed, still-editable .docx.
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.
-
Your documents stay on your device
Documents — PDFs, Word files, photos — are processed in your browser and stored in your local library. They are never uploaded to a server.
-
No account, no email
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?
PDFs — from your open tabs or uploaded from your computer — plus Word documents (.docx) and photos or scans (PNG, JPG, WebP, HEIC, and more). Signed documents can be downloaded as PDF, JPG, or PNG, and Word uploads also come back as a signed .docx.
Can I sign a Word document (.docx)?
Yes. Upload a .docx and sign it like any PDF. You get two files back: a signed PDF, and your original Word document with the signature embedded — still editable, barely larger than the original, with the signature anchored next to the text you signed. The conversion happens entirely on your device.
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.
