What is Add Signature to PDF?
Add Signature to PDF lets you sign a document by drawing your signature with a mouse, trackpad or finger, or by uploading an image of your signature. Place it anywhere on the page, resize and rotate it, then download the signed PDF. It's meant for everyday sign-offs, not as a legally verified digital signature.
How to use Add Signature to PDF
- Choose a PDF file, or drag and drop it into the tool.
- Draw your signature on the pad, or switch to Upload and choose a PNG or JPG.
- Click the page preview to place the signature, drag to reposition, set the width and rotation, then click Add Signature to This Page and download.
Features
- Draw a signature by hand or upload an existing image.
- Click-to-place signature with drag-to-reposition.
- Adjustable width and rotation.
- Transparent background when drawing, so only the signature shows.
- 100% client-side — your PDF never leaves your browser.
Frequently Asked Questions
Is my PDF uploaded to a server?
No. Add Signature processes your file entirely in your browser. Your PDF and your signature never leave your device.
Is this a legally binding digital signature?
No. This tool draws or places a signature image onto the page — it does not create a legally verified digital signature with cryptographic identity verification. For legal use cases, check the requirements that apply to you.
Can I draw my signature with a mouse or my finger?
Yes. The signature pad works with a mouse, trackpad or touchscreen.
Can I upload a signature image instead of drawing one?
Yes. Switch to Upload and choose a PNG or JPG of your signature. A PNG with a transparent background works best.
