Features

Everything you need.
Nothing you don't.

Designed for anyone who just needs to sign a PDF quickly — no bloat, no friction, no privacy trade-offs.

Your files never leave your device

PDFArena is 100% client-side. Every PDF you open, every signature you draw, every download — all processed locally in your browser using pdf-lib. No server ever sees your documents.

Draw your signature

Use a mouse, trackpad, or touchscreen to draw a natural handwritten signature — just like pen on paper.

Add text annotations

Type names, dates, or any information directly onto the PDF. Drag to position and style however you need.

Multi-page support

Navigate through multi-page PDFs and sign or annotate any page. Each page's overlays are tracked independently.

Instant download

Download your signed PDF in one click. Signatures and annotations are permanently embedded — no special viewer needed.

Free forever, no tricks

No free tier with a paywall. No "premium" features. No account required to download. Just open, sign, save.

How it works

Sign your PDF in three steps.

No learning curve. No account setup. Just open the app and done in under a minute.

Add your signature

Draw your signature with a mouse or finger, or upload an image of your signature. Drag it into position on the page.
