A little more context
About Sign PDF
Use Sign PDF to place a visible typed, drawn, or uploaded signature appearance on selected pages for routine review and document workflows.
What is Sign PDF?
Sign PDF places a visible typed, drawn, or uploaded signature appearance on selected pages. It is suited to routine sign-off copies, but it is not a certificate-based digital signature or identity-verification service.
What happens to your file?
Signature placement runs in your browser. Uploaded signature images and drawing data are used for the current workflow and are not saved by the app.
Features in this tool
- Type a signature or draw one with a pointer or touch device.
- Upload a PNG, JPG, or WebP signature image.
- Set the signature size and position on selected pages.
Common problems and solutions
- The signature is hard to read: Choose a larger size or a clearer image, then inspect the exported page at normal reading scale.
- The signature covers text: Move or resize it before downloading and check every selected page.
- A recipient needs a certified signature: This tool creates a visible appearance only; use an appropriate certificate-based signing workflow for that requirement.
Tips and limitations
- This creates a basic electronic signature appearance, not a certificate-based digital signature or proof of identity.
- The signature is added to the downloaded copy; keep the source PDF if you need an unsigned version.
- Check that the signature does not cover text, fields, or page numbers.
