Why this signature tool

🔒 Fully private

Your PDF and signature never leave your browser — nothing is uploaded. Ideal for contracts, agreements and anything confidential.

✍️ Upload or draw

Drop in a signature photo (its background is removed automatically) or draw one with your mouse, finger or Apple Pencil. Add a printed name and a stamp like “Approved”.

📄 No quality loss

The signature is placed as a layer on top of the page. The document's text, vectors and images are never rasterized — the original stays untouched.

How to add a signature to a PDF

  1. Create. Upload a signature image (background removed automatically) or draw it on the pad. Optionally add a printed name and stamp text.
  2. Style it. Set the name position, font, colour and the overall opacity — and save the signature to reuse later.
  3. Place. Open your PDF and drag, scale and rotate the signature. Choose the current page, selected pages, a range or all pages.
  4. Download. Apply to get a signed PDF; the original document is never changed.

Frequently asked questions

How do I sign a PDF?
Create a signature by uploading an image or drawing it, adjust its appearance, then open your PDF and drag the signature into place. Choose the current page, selected pages, a range or all pages, and download the signed PDF.
Can it remove the white background from a signature photo?
Yes. For a JPG or WebP with a light, roughly uniform background, the background is removed automatically and edges are de-fringed so no white halo remains. A sensitivity slider fine-tunes it; already-transparent PNGs are used as-is.
Can I draw my signature?
Yes. The drawing pad works with a mouse, touchscreen, stylus or Apple Pencil, with adjustable thickness and colour plus undo/redo. It's saved as a transparent image automatically.
Does it change the PDF or reduce quality?
No. The signature is added as a separate layer on top of the content. The page's text, vectors and images are never rasterized or altered, and the original document is left untouched.
Is my document private?
Completely. The whole tool runs in your browser — the PDF and your signature never leave your device.
Can I reuse my signature later?
Yes. Save several signatures (Personal, Work, Company Stamp…) locally in your browser and pick one next time. They're stored only on your device.
