Sign a PDF

Draw a signature, type your name or choose a signature image, then place it on one PDF page. This creates a visible mark, not a verified digital signature.

How to place a signature on a PDF

STEP 1

Choose the PDF and page

Open one PDF and select the page containing the signature line. Wait for its preview before positioning the mark.

STEP 2

Make and position the signature

Use Draw, Type or Upload. A transparent PNG avoids a white rectangle around an uploaded signature. Drag the mark in the preview and adjust its width.

STEP 3

Save and inspect the signed copy

Save the -signed.pdf result and open it to check the selected page. For another page, reopen the saved copy and repeat. Your original remains separate.

What this signature does

The tool embeds a signature image at your chosen position. It does not verify who signed, issue a certificate, collect recipient consent or provide an audit trail. Ask the recipient whether a visible electronic signature is acceptable before relying on the result.

Check placement at normal reading size and on the saved page, especially for rotated pages or a long typed name. Rewriting an already digitally signed PDF can invalidate its existing signature. Keep the original for your records.

If the preview fails, confirm the PDF opens normally and is not locked. Use an authorised unlocked copy if necessary. For a photographed signature with an unwanted background, use Erase background manually; Signature maker instead creates a new drawn or typed transparent PNG.

Questions

Can I sign every page at once?

No. One operation applies the signature to the selected page. Reopen the saved output for each additional page.

Is this a certificate-based digital signature?

No. It adds a visible image and provides no identity verification or signing audit trail.

Is my file uploaded anywhere?

No. The work happens inside this tab, on your own machine. Open your browser's network tab while you use the tool, there is no request carrying your file.

Is there a file size limit?

Practical limits depend on the tool, browser and available device memory. Large files can fail even when no explicit limit is shown. Keep an original and use a smaller job if this device cannot finish it.

Do I need an account?

No, and there is no daily limit either. There is nothing to sign up for.

What kind of signature this is

This places a picture of your signature on a page of the PDF. It is a visual mark, like signing a printed page and scanning it. It is not a cryptographic digital signature and carries no certificate or proof of who applied it.

That is enough for many forms, letters and agreements where a signature image is accepted. It is not enough where a qualified or certificate based digital signature is required, so check what the recipient needs.

Getting a signature that looks right

Draw it with a mouse, finger or stylus, type your name in a handwriting style (up to forty characters), or upload an image. A PNG with a transparent background looks best, because a photo of a signature on white paper will show a white box.

Choose the page, set the size between 10 and 60 percent of the page width, and drag the signature into place on the preview. One signature goes on one page each time, so to sign several pages run it again on the saved copy. The signature becomes part of the page and cannot be edited afterwards, so keep your unsigned original.
