Draw your signature in the box, or leave it empty and type your name; then choose last page, first page or every page, and pick one of four corners. Position comes from a list rather than a drag, the width defaults to 180 points, and the result is an electronic signature in the everyday sense — not a certificate-backed one that proves who signed and that nothing changed afterwards.

Open Sign PDFWhat you are adding, and what you are not
A signature placed this way is drawn onto the page as an image. It travels with the page, scales when the page is scaled and appears in print, which is enough for the large majority of everyday purposes: a lease, a consent form, an invoice, an internal approval. It is a visible mark of assent, and in that everyday sense it is a perfectly ordinary electronic signature.
It is not a certificate-based digital signature, and the distinction is worth being clear about. A certified signature uses a key pair to bind an identity to the document and to detect any later alteration, so a reader can verify both that the signer is who they claim and that nothing has changed. A drawn image carries no such guarantee. Anyone can copy the picture of a signature onto a page, and nothing in the file would reveal that it happened.
If the recipient is a bank, a government body or a counterparty who has specified a certified workflow, this tool is the wrong instrument and no amount of care over placement will change that. If the recipient simply needs your mark on the page, it is the right one, and it does the job without a subscription, an account or an upload.
Step by step
Add the PDF
Drop the document onto the box or click to browse. It stays on your device for the whole operation, including the moment the signature is written.
Draw your signature, or type it
Sign in the box with the mouse or with a finger on a touchscreen. If the box is left empty, the name you type is rendered in a handwriting face instead. Drawing takes precedence, so a stray stroke left in the box will override a typed name.
Choose the page
Place on decides whether the signature lands on the last page, the first page, or every page of the document. A contract is normally signed on the last page; a policy or a set of terms is sometimes signed on every page.
Choose the corner
Position offers bottom right, bottom left, bottom centre and top right. Bottom right suits most documents; the top-right corner is the one to reach for when the lower part of the page is already crowded.
Adjust the width and add a date if you want one
Advanced options holds the signature width, which defaults to 180 points, and a date line drawn as small text beneath the signature. A long name looks better a little wider, and the height follows the width so the signature is never distorted.

The signature is written onto the pages you selected and the file is saved. The document you started from is left exactly as it was.
Check the placement before sending it on
Open the result and glance at the signed page. A long name at a large width can overrun a corner, and a date line placed very low can sit on top of the signature itself.
Choosing where the signature goes
Placement is chosen from a list, then refined with the width. Every setting is visible on the finished page before you send it.
| Setting | Options | When to pick it |
|---|---|---|
| Place on | Last page, first page, every page | Last page for contracts, every page for terms and policies. |
| Position | Bottom right, bottom left, bottom centre, top right | Bottom right as the default; top right when the lower part of the page is full. |
| Signature width | 60 to 400 points, default 180 | Widen for a long name, narrow it when the signature crowds the margin. |
| Date line | Free text, optional | Add it for dated agreements; leave it empty if the page already carries a date field. |
| Input method | Drawn stroke or typed name | Drawn for a personal signature, typed as a fast fallback. |
| Height | Follows the width | Not set separately, so the signature keeps its proportions. |
Mistakes to avoid
A drawn signature being ignored
If a typed name appears instead of your drawing, the box was treated as empty and the stroke did not register. Watch the ink appear as you draw; if nothing shows, try again with a slower stroke.
A long name running off the page
At a wide setting, a long typed name can overflow the corner. Reduce the width in Advanced options or switch to the opposite corner, which has more room to spare.
The date landing on the signature
A date line added beneath a signature placed very low on the page can overlap it. Use the top-right corner, or leave the date field empty.
Treating it as a certified signature
The mark is an image, so nothing in the file proves who put it there or that the document has not been altered since. A workflow that requires verification needs a certificate-based signature, and this tool cannot provide one.
