Sign PDF

How it works

1. 1

   Open your PDF Drop the PDF on the upload area or click it to choose the file. The first page opens in the editor, with thumbnails of all pages on the left of wider screens.

2. 2

   Create your signature In the Signature Library panel, press "Signature", then draw, type or import it and press "Save". "Initials" and "Short signature" work the same way.

3. 3

   Place it on the page Drag the item from the library onto the page. It lands where you drop it, at a default size, on the page shown.

4. 4

   Adjust and repeat Drag the signature to move it and pull its handles to resize it. Pick another page in the thumbnail column to sign it too.

5. 5

   Download the signed PDF Press "Download" in the toolbar. Your file is saved with _signed added to its name, for example contract_signed.pdf.

Draw, type or import your signature

Draw uses your mouse or trackpad on a large pad. Pick one of five ink colors (black, blue, red, green or purple) and set the line with the Thickness slider, from 1 to 8. If the first try is not right, press "Clear" and start again.

Text turns your typed name into a signature in one of four font styles, in the same five colors. The styles use fonts installed on your device, so the same choice can look different on another computer or phone.

Import image takes a PNG or JPEG picture of your handwritten signature. A PNG with a transparent background leaves the page visible around the signature; a JPEG keeps its background, such as the white of the paper, as a rectangle on the page.

Initials and short signatures use the same editor and are stored in the library with their own label, so you can keep a full signature and a short mark side by side.

Place, resize and sign several pages

A placed signature starts at a default size, centered where you drop it. Select it to show eight handles for changing its width and height, and drag it anywhere on the page. Choose your zoom level, from 50% to 300%, before you place a signature and keep it until you download: changing it moves the signatures already placed. In a PDF whose pages are not all the same size, signatures can come out shifted or stretched, so check every signed page.

The red cross removes a signature, and the blue button next to it makes a copy, slightly offset, on the same page. To sign several pages, open each one from the thumbnail column and drag the item from the library again; the panel counts your signatures in total and on the current page.

To fix a mistake, remove the signature with the red cross, or remove every placed signature with "Delete all". Nothing is written into the PDF until you press "Download", and it is worth opening the downloaded file to check each signature.

Your library lasts only while this page stays open. It is still there if you open another PDF with the Change file button, but it is lost when you reload or leave the page, so keep a PNG of your signature if you sign often.

What this signature is, and when you need a certified one

This tool adds a simple visual signature: an image of your signature drawn onto the page. The PDF carries no certificate, no timestamp and no audit trail, and it is not locked afterwards: it can still be edited like any PDF.

When the requester asks for a certificate-based digital signature, a record of who signed and when, or identity checks, use a dedicated e-signature service that provides them. If you are unsure which kind is expected, ask the person or organization that sent you the document.
