Sign a PDF
Draw with a mouse, trackpad or pen, type your name in a handwriting font, or upload an image. Place it, size it, export.
Processed in your browser — the file is not uploaded.
Three steps
Drop the PDF. The signature pad opens straight away.
Draw, type or upload. Pen dynamics make a drawn signature thicken and thin like real ink.
Place it and export. Drag the signature where it belongs and resize it from the corner.
What happens to the file
What stays intact
- Drawn signatures are written as vector path operators, not a bitmap — no fuzzy edges when zoomed or printed.
- The rest of the page is untouched; the signature becomes part of the page content.
- Sign in and your signatures are saved for the next document.
- Nothing is uploaded while you are anonymous — the signature never leaves the browser.
What it will not do
- This is a visible signature, not a certificate-based digital signature with an audit trail.
- There is no signing workflow: no sending to a counterparty, no reminders, no signing order.
- Signature fields that already exist in an AcroForm are not filled in — the signature is placed on the page.
Questions about this tool
Is this a legally binding e-signature?
It is a visible signature on the document, the same as signing a printout and scanning it. PDFinline does not issue certificate-based digital signatures or an audit trail, so for regulated workflows use a service built for that.
Can I sign on a phone?
Yes. The signature sheet accepts a finger or a stylus, and the pad is sized for touch.
Can I add a date or initials too?
Yes — add text boxes anywhere on the page, or place a second, smaller signature as initials.
Will the signature survive printing and flattening?
Yes. It is baked into the page content on export, not stored as an annotation that a viewer might hide.
