Top 5 Free Tools to Sign Documents Online (No Signup Required)

Let’s be honest — most people who just want to sign a document online for free end up stuck in a loop:

• You upload the file

• You’re asked to create an account

• You confirm your email

• Then you find out it’s a “trial”

• And your signature is watermarked, blurred, or locked behind payment

For something that should take less than 60 seconds, most tools make it way harder than it needs to be.

So we did the digging for you.

🥉 3. PDFescape – Browser-Based PDF Editor

Best For: People who want to add text, annotations, and signature in one place

PDFescape is a web-based PDF editor — it’s not just for signing, but it includes a basic freehand tool that lets you draw a signature.

How it works:

• Upload your PDF (up to 10MB or 100 pages)

• Use the “Freehand” tool to draw your signature

• Drag and place it on the doc

• Download or save the edited file

Pros:

• No signup required

• No watermark

Cons:

Good in a pinch, especially if you want to add text and annotations as well.

🏅 4. DocHub – Feature-Rich PDF Signing

Best For: Users who want more formatting and collaboration tools

DocHub has been around for a while and is pretty solid if you're looking to do more than just sign. You can edit, highlight, redact, and annotate PDFs.

Free plan highlights:

• Upload and sign PDFs

• Add text fields and checkboxes

• Send documents to others for signature

• Google Drive integration

But here's the catch:

• You can sign documents online free, but after a few uses, they require login

• Some features only work after signup

• File storage is linked to your DocHub account

Still, for casual use, you can get through a couple of documents without creating an account.

🧩 5. Soda PDF Online

Best For: Quick signatures if you’re okay with a more limited interface

What you can do:

• Upload PDF

• Draw or upload a signature

• Drag and drop to place

• Download the signed version

Things to note:

• You get about 3 free tasks per day

• Watermarks sometimes appear on edits (not always on signatures)

Not the most elegant, but still useful when you need a fast, no-signup signing experience.
