## Direct answer

Open [Sign PDF](https://mypdf.space/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.

## Introduction

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.

## Steps

1. Open [Sign PDF](https://mypdf.space/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

- Visual signature only — not cryptographically verifiable.
- Password-protected PDFs must be unlocked first.

## FAQ

### Can I sign a PDF online for free without Adobe?

Yes. Use [Sign PDF](https://mypdf.space/sign-pdf) in your browser — free, no upload, no watermark.

### Is a drawn signature legally binding?

It depends on jurisdiction and context. It is not a certificate-based digital signature. For high-stakes contracts, use a dedicated e-sign service.
