Send a PDF for signature in four steps
1. Click Start free and upload your PDF.
2. Add each signer's name and email. Add a mobile number to send by text as well.
3. Carta finds the signature, initials and date lines. Drag any field to adjust it, or add more.
4. Write a short Presentation Letter and click Send. When everyone signs, the sealed copy arrives by email.
Signing a PDF you received?
If someone sent you a Carta Ink link, just open it, review the document and click Finish and seal. You never need an account.
Why not print, sign and scan?
An electronic signature is faster and leaves a better record. Every Carta Ink document is sealed with a Certificate of Execution showing who signed and when, and a digital fingerprint that shows if anything changes.
