How to Sign a PDF
Signing takes less than a minute:
- Drop the document - The first page renders as a preview and the source file's SHA-256 hash is shown so you can verify the original later.
- Create your signature - Draw it with a mouse or finger, type your name in one of five styles, or upload an image. Save it in the browser to reuse next time.
- Place and sign - Click the preview to set the position, choose this page, a range, or all pages, then sign. The output hash appears after download.
Visual Signatures, Saved Signatures, and Where They Live
Two decisions matter when you sign documents regularly: what kind of signature you use and where it is kept.
- Visual versus certificate signatures - This tool draws your signature image onto the page. It evidences intent but proves nothing about identity. Certificate signatures bind a cryptographic key to a verified identity and are what regulated workflows expect.
- Three sources, one studio - Draw, type, and upload all feed the same placement engine, so you can compare which looks most like your ink signature before committing.
- Saved signatures - Stored in IndexedDB on your device only. Clearing browser data removes them; nothing syncs to a server.
- Placement by page - Sign one page, a custom range, or every page with proportional positioning that respects mixed page sizes.
- Date stamp - Optional, drawn as real PDF text from your device's local date, so it stays selectable in any reader.
- SHA-256 transparency - Source and signed hashes are displayed so recipients can confirm which exact file you signed.

Frequently Asked Questions
How do I sign a PDF online free?
Drop the PDF, create a signature by drawing it, typing your name, or uploading an image, then click the page to place it and press Sign PDF. The signed copy downloads with a date stamp if you keep that option on.
What is the difference between a visual signature and a certificate signature?
A visual signature is an image of your signature placed on the page. It shows intent and is accepted for everyday documents, but it carries no cryptographic identity. Certificate signatures (digital IDs) use keys issued by a certificate authority and are what legal frameworks such as eIDAS or ESIGN often require for formal signing.
Can I reuse a saved signature?
Yes. Press Save signature to store it in your browser's local database (IndexedDB), then click it in the saved list on any future signing session on the same device.
Where is my signature stored?
Only in this browser's local storage on your device. It is never uploaded, never sent with the document, and clearing your browser data removes it.
Can I sign multiple pages at once?
Yes. Choose This page, All pages, or a custom range like 1, 3-5. The same signature and position apply proportionally to every selected page.
Does the date come from my device?
Yes. The stamp uses your device's local date, drawn as real PDF text so it stays readable and selectable in any reader.
Is the signed PDF accepted by others?
For contracts, invoices, and approvals, visual signatures are widely accepted. When a counterparty requires tamper evidence or identity verification, ask for a certificate-based digital signature instead. This tool states its limits openly.
