How to Sign a PDF Online for Free (No Adobe, No Sign-Up)
You Don't Need Adobe to Sign a PDF
Adobe Acrobat charges $19.99/month largely because of its e-signature features. But signing a PDF digitally is something you can do completely free in any browser.
How to Sign a PDF Free (Step by Step)
- Draw — use your mouse or finger (touchscreen)
- Type — select a handwriting font and type your name
- Upload — use an image of your actual signature
No account needed. Processing runs in your browser — the file is never uploaded.
Draw vs Type vs Upload — Which to Use?
Draw: Best for touchscreens. Natural-looking, unique to you.
Type: Best for keyboard users. Choose from several handwriting fonts. Quick and clean.
Upload: Best for professional/legal use. Scan or photograph your real signature on white paper, upload as PNG/JPG.
Is a Digital Signature Legally Valid?
For most everyday purposes (internal forms, consents, rental agreements between private parties) — yes, a typed or drawn signature is legally sufficient in most countries.
For legally binding contracts under eIDAS (EU), ESIGN/UETA (US), or contracts requiring a notary — you need a qualified electronic signature (QES) from a certified provider like DocuSign or Adobe Sign. This is a small subset of use cases.
Signing on Mobile
The Draw method works well on smartphones and tablets — just use your finger. The entire tool is mobile-optimised. No app to install.
Add a Date Stamp
After placing your signature, use the text tool in the PDF Editor to add a date next to your signature. This is standard practice for signed documents.
Need Multiple Signers?
DoctorDocs Sign PDF is designed for single-user signing. For multi-party workflows (where several people need to sign), consider a dedicated service like SignWell (free tier available).
