How to sign a PDF
- Upload your PDF (drag & drop or browse).
- Choose Sign PDF, upload your signature image (a transparent PNG works best), and pick the page, position and size.
- Download the result and compare it with your original before sharing.
A practical starting point
Use a transparent PNG cropped close to the signature. Select the physical page number and inspect the output against the signature line.
Frequently asked questions
What are the limits of Sign PDF?
This is a visual stamp, not a certificate-based digital signature, identity verification or tamper-evident signing service.
How should I check the Sign PDF result?
Check size, background and placement at full zoom. Ask the recipient which signing method they accept; use a certificate-based service when that is required.
