A PDF signed in just a few minutes
Getting a PDF signed online takes less than 5 minutes with an electronic signature platform. No need for Adobe Pro, no need to print, no need to scan.
The 5 steps
1. Choose a platform
Select a platform compliant with eIDAS (Certyneo, Yousign, DocuSign, etc.). A free plan is sufficient to get started.
2. Upload the PDF
Drag and drop your file into the interface. Most platforms accept:
- PDF (native format, recommended)
- Word (automatically converted)
- Images (best avoided if possible)
3. Add the signers
Enter the name and email of each signer. For advanced signature (AES), also add the phone number (OTP SMS).
4. Place the signature fields
Drag a "Signature" field to the desired location on the page. For multiple signers, one field per person with different colours.
5. Send
Click "Send". Each signer receives an email with a secure link. You track the status in real time.
What the signer receives
- an email with a unique link
- opening of the PDF in the browser
- a click on "Sign"
- optionally an OTP code by SMS (for AES)
- immediate confirmation
Total time for the signer: 1-3 minutes.
Best practices
- Review the PDF before sending (no corrections possible once signed)
- Set an expiration date (15-30 days)
- Enable automatic reminders
- Test first with a non-critical document
Common mistakes
- Uploading a poor quality scan (unreadable on mobile)
- Forgetting a signature field
- Entering the wrong email
- Sending without testing
