Draw your signature and place it on any PDF page. No upload, no account, no watermark — completely free and private.
Sign any PDF by drawing your signature directly in your browser — no upload, no account, no watermark. Draw with your mouse or finger (on mobile), choose where to place it, and download the signed document instantly. Unlike DocuSign, HelloSign, or Adobe Sign, this tool is completely free with no signup. Your document and signature never leave your device — everything runs locally using pdf-lib.
Drop your PDF, draw your signature on the white canvas, select which page and position to place it, then click Sign PDF. The signed document downloads instantly. Works on desktop (mouse) and mobile (finger/stylus).
This adds a visual signature image to your PDF. For most business and informal purposes (contracts, agreements, forms, invoices), this is widely accepted. For documents requiring certified digital signatures with cryptographic verification, you may need a qualified e-signature service. However, the vast majority of everyday signing needs are covered by a drawn signature.
No. Everything runs in your browser using pdf-lib. Your PDF and your signature never leave your device — completely private and secure. No server, no cloud, no third-party access.
You can place your signature on any single page per operation. To sign additional pages, download the signed PDF and run it through the tool again. Each pass adds your signature to one more page.
