What Is Document Signer?

Document Signer is a comprehensive e-signature tool that goes beyond basic PDF signing. Add full signatures, initials, dates, custom text fields, and checkmarks to any PDF document. It handles the complete document signing workflow — the same field types you'd find in DocuSign or Adobe Sign — entirely in your browser with no server, no account, and no cost.

How to Use This Tool

Upload a PDF document, then select a field type from the toolbar: signature, initials, date, text, or checkmark. Create your signature by drawing, typing, or uploading an image. Place fields anywhere on any page — drag to reposition and resize as needed. Use "Apply to All Pages" to add your signature or initials to every page at once. When finished, download the completed document. Everything runs in your browser — your files and signature data never leave your device.

Why Use Document Signer?

Commercial e-signature platforms charge $10–$30 per month and upload your documents to their servers. This tool provides the same core field types for free, with complete privacy since everything is processed client-side using JavaScript. It's ideal for contracts, agreements, consent forms, tax documents, and any PDF that needs signatures, initials, and dates without printing a single page. For a walkthrough of PDF signing, see our step-by-step guide.

Frequently Asked Questions

Is this a legally binding e-signature?+
In the US, the ESIGN Act (2000) and UETA make electronic signatures legally equivalent to handwritten signatures for most contracts when both parties agree to sign electronically. This tool produces visible signature images embedded in the PDF, which is the same approach used by many commercial e-signature products.
Are my documents uploaded to a server?+
No. Your PDF is opened, rendered, signed, and saved entirely on your device using JavaScript. Nothing leaves your browser. You can verify by checking the network tab in your browser's developer tools.
What field types can I add?+
You can add five field types: full signatures (drawn, typed, or uploaded), initials, today's date, custom text (names, titles, addresses), and checkmarks for checkbox fields.
Can I sign every page at once?+
Yes. After placing a signature or initials on one page, use the Apply to All Pages button to automatically copy that placement to every page in the document.
