Key takeaways
- 01You can draw a signature, type one, resize it, and place it on any page.
- 02The PDF is previewed and signed locally in the browser, so the file is not uploaded.
- 03For regulated or qualified e-signatures, use a provider approved for that specific workflow.
Why browser-only signing matters
Signing a PDF usually means the file contains something important: a contract, approval form, invoice, school document, or personal record. Uploading that file to a random converter just to place a signature is unnecessary when modern browsers can preview and edit the PDF locally.
Handytool's PDF signer loads the document in your browser, renders the pages for review, and embeds the signature into a new PDF on your device. That keeps the workflow fast while avoiding the privacy tradeoff of sending the file away.
How to sign a PDF online
The workflow is designed for the everyday version of PDF signing: place a visible signature, check the page, and download the finished file.
- 01
Open the PDF signing tool
Go to Handytool's Sign PDF tool and drop your PDF onto the page, or choose it from your device.
- 02
Create your signature
Draw with a mouse, trackpad, stylus, or finger. If you prefer a cleaner look, type your name and choose one of the signature styles.
- 03
Place it on the right page
Use the full PDF preview to find the signing area, then drag, resize, and position the signature exactly where it belongs.
- 04
Download the signed copy
Click the download action to export a new PDF. The original file is not changed, and the signed copy is saved to your device.
Quick checks before sending the signed PDF
A one-minute review prevents the most common signature mistakes.
- 01Confirm the signature is on the correct page and line.
- 02Zoom in once to check that the signature is readable.
- 03Make sure initials, dates, or extra signature fields are not missing.
- 04Open the downloaded file before sending it to confirm the signature saved correctly.
- 05Keep an unsigned original if you may need to edit the document again later.
What happens to the file?
The PDF is parsed, previewed, signed, and exported in the browser with client-side PDF libraries. Handytool does not need the file on a server to add the signature.
That also means the practical limit is your device. Very large scanned PDFs can use more memory, especially on older phones, but normal contracts and forms usually sign in seconds.
PDF signing FAQ
Can I sign a PDF without creating an account?

Can I sign on a phone?
Yes. You can draw with your finger or stylus, then drag the signature into place on iPhone, iPad, and Android browsers.
Can I put signatures on multiple pages?
Yes. Add the signature where needed, duplicate it if useful, and place signatures on different pages before exporting.
Is this a certified digital signature?
No. It adds a visible electronic signature to the PDF. If your document requires certificate-backed or qualified signing, use the required regulated provider.
