How to sign a PDF without Adobe

Short answer
Open Sign PDF, draw or place your signature, and download. This is a visual stamp for everyday approval. For certificate-based legal e-sign, use a dedicated service or Acrobat.
Most people who “need Adobe to sign” only need a signature image on a page. You can do that in the browser without a subscription.
Know the difference: visual signatures vs cryptographic digital signatures. mypdf does the first.
Step by step
- 1
Open Sign PDF and drop in an unlocked PDF.
- 2
Draw or upload a signature image and place it on the page.
- 3
Download and open the file once to confirm placement.
- 4
If the form has fillable fields, use Fill & sign instead for typed fields plus a signature.
When you still need Acrobat or DocuSign
Certificate-based signatures, workflow audit trails, and some government portals require a proper e-sign product. A drawn signature will not satisfy those.
Limits worth knowing
- Visual signature only — not cryptographically verifiable.
- Password-protected PDFs must be unlocked first.

Frequently asked questions

Yes. Use [Sign PDF](/sign-pdf) in your browser — free, no upload, no watermark.Is a drawn signature legally binding?
