Sign a PDF in Your Browser — Draw or Type a Signature, No Upload

Browser-local PDF tool

Use Sign PDF

Draw, type or upload a signature and place it on the page. Everything happens in this tab — the document is not uploaded and no account is needed.

PDF to sign

This is a visual signature only — not a cryptographic or legally verified e-signatureIt draws a picture of your signature onto the page, which is what most forms, letters and internal approvals actually ask for. It is not DocuSign or Adobe Sign: there is no certificate, no identity verification, no trusted timestamp and no audit trail, so nothing here proves who signed or that the document is unchanged afterwards. Building that needs a trusted third party, which a browser-local tool cannot be. Where a signature must be legally verifiable, use a qualified e-signature service.

Placement was checked against the coordinate flip that makes this easy to get wrong: a page preview measures from the top-left while a PDF measures from the bottom-left, so a signature placed near the bottom of the preview must land near the bottom of the page rather than mirrored to the top. Signing page two and reading the text back confirms the mark lands on the chosen page and on no other, and a signature is sized to width with its height following its own proportions so it is never stretched.

About Sign PDF

Most of the time, signing a document means putting a picture of your signature in the right place and sending it back. A landlord wants the tenancy agreement initialled. A client wants the quotation signed off. A school wants a consent form returned. None of those need a certificate authority; they need a visible mark where the line is. That is exactly what this does, and it is careful to claim nothing more. The signature is drawn onto the page itself rather than attached as an annotation, so it becomes part of the page content and cannot be selected and dragged away in a viewer. You can draw with a finger or trackpad, type a name, or bring your own PNG. Then you click the page where it should sit, drag it into position, and size it. The document is opened, previewed and rebuilt here in the tab: it is not uploaded, and there is no account to make.

What happens to the PDF

The PDF is rendered to page previews in the browser so you can see where the signature is going. That preview is what you click on; the position is stored as a fraction of the page, so it lands in the same place regardless of what size the preview was drawn at.
Draw with a pointer, finger or stylus on the pad. The drawing is trimmed to the ink before it is placed, so you get your signature rather than your signature floating in a large transparent rectangle.
Typing a name draws it in an italic serif face. It is a typed name and the page says so — it looks like a signature block, not like handwriting.
An uploaded signature is decoded by the browser and re-encoded as a PNG before it is placed, so any image your browser can open works rather than only PNG and JPEG. A source PNG with a transparent background sits on the line; a JPEG carries a solid box that covers whatever is behind it, and you are told when that has happened.
The width is set as a percentage of the page and the height follows the signature's own proportions, so it is never stretched — a stretched signature is the thing that most makes a document look tampered with.
Choose another page and place it again to sign or initial several pages in one pass. Each placement is listed before you commit.
The signature is drawn into the page content stream, so it is burned in rather than sitting as a removable annotation.

Common sign pdf jobs

A tenancy or service agreement

Place the full signature on the signature line of the last page, then initial the earlier pages by choosing each one and placing a smaller version.

A quotation or purchase order to approve

Sign, then flatten separately if the figures on the same document also need fixing so they cannot be edited afterwards.

A consent or permission form

Draw the signature rather than typing it where the form asks for a handwritten one. Nothing about the file leaves your device either way.

A scanned document you cannot type into

A scan has no form fields, but it still has pages. A visual signature works on it because it is drawn onto the page rather than into a field.

Check before relying on the PDF

This is a visual signature and nothing more. It is not a cryptographic signature, not a certificate-based digital signature, and not a legally verified e-signature. There is no identity verification, no trusted timestamp, no audit trail and no tamper-evidence, so nothing in the resulting file proves who signed it or that it has not been altered since.
It is not DocuSign, Adobe Sign, or any qualified e-signature service, and it does not attempt to be. Those services exist to produce evidence a third party will accept; producing that evidence requires being a trusted third party, which a tool running entirely in your own browser cannot be by definition. Where a signature must be legally verifiable — many property, lending and cross-border matters — use a qualified provider.
Anyone can place any image on any PDF. That is true of every visual signing tool including the drawing tools built into operating systems, and it is exactly why a visual signature is evidence of intent between parties who already trust each other rather than proof of identity.
Password-protected PDFs are refused, because the document cannot be modified while it is encrypted.
A signature image is decoded and redrawn before it is placed, so a damaged or truncated file is refused at that point rather than reaching the PDF writer, where a half-written image would stall rather than fail cleanly. The redraw is why the upload is not limited to PNG and JPEG.
Check the position in the finished PDF before sending it. The preview is a rendering rather than the page itself, so on a dense form a signature can still sit slightly differently from where it looked.

Questions about Sign PDF

Is this a legally binding e-signature?

No. It produces a visible signature on the page and nothing else — no certificate, no identity check, no timestamp and no audit trail. Many everyday agreements are accepted with a visual signature between parties who already know each other, but if a signature has to be legally verifiable, use a qualified e-signature service instead.

How is this different from DocuSign or Adobe Sign?

Those services verify who signed, record when, and keep an audit trail a third party can check. All of that depends on a trusted third party holding evidence. This tool holds nothing and contacts nobody, so it can offer the visible mark and none of the proof.

Can the signature be removed from the PDF afterwards?

Not by clicking it. It is drawn into the page content rather than added as an annotation, so a viewer cannot select and delete it the way it could a sticky note. Anyone with a PDF editor can still alter a page, as they could with any document.

Are my files uploaded?

No. The PDF is opened, previewed, signed and rebuilt inside this browser tab, and this site has no endpoint that accepts a file. Your signature image never leaves the device either.

Should I use a PNG or a JPEG for my signature?

PNG, if you have the choice. It supports a transparent background, so the signature sits over the line on the form. A JPEG always carries a solid rectangle, which blanks out whatever it covers, and you are told when that happens. Other formats are accepted too — they are converted to PNG here — but a format without transparency cannot gain it in conversion.
