  2. Create your signature – Draw, type, or upload an image signature.
  3. Adjust position & size – Set X/Y coordinates and width (in points).
  4. Click “Sign PDF” – The signature will be placed on the first page.
  5. Download the signed PDF – Save it to your computer.

❓ Frequently Asked Questions

🔹 Is my PDF uploaded to a server?
No. Everything runs locally using PDF-Lib and the browser’s canvas. Your files stay completely private.
🔹 Can I sign multiple pages?
The current version adds the signature only to the first page. For multiple pages, you can sign separate copies and combine them.
🔹 What file formats for signature images?
JPG, JPEG, and PNG are supported. The image will be embedded as is (no lossy compression).
🔹 Can I adjust transparency?
PNG images with transparency are supported. For drawn signatures, the background is white; you may need to set a transparent background later.
🔹 Is there a file size limit?
PDFs up to 100 MB work reliably. Very large files may take longer due to processing.
🔹 Is this tool free?
Yes, completely free for personal and commercial use, with no watermarks or registration.
