Jotform Sign is built on top of Jotform's form builder. If you already live in Jotform, it is a natural extension.
If you start with a PDF rather than a form, the comparison is more interesting.
Where Jotform Sign wins
Forms-first signing. Excellent for HR onboarding, application forms and structured intake where you want fields collected before signature. Strong integrations with Google Drive, Dropbox and a hundred other tools.
Where Flint wins
If you already have the document as a PDF — most contracts, leases, NDAs — Flint signs it directly. Sign-pdf, edit-pdf, merge-pdf all live in one place. No need to rebuild the contract as a form first.
Pricing compared
Jotform's signing tier costs vary by plan and submission volume. Flint Pro is a flat annual plan with no submission counts. For document-first signers, Flint is usually cheaper.
Best for…
Jotform Sign for HR, intake and structured form workflows. Flint for sign-this-PDF use cases.
FAQ
Can Jotform sign any PDF?
It can convert PDFs into Jotform documents and sign them, but the experience is form-centric. Flint's editing is closer to the PDF itself.
Does Flint have form fields?
Flint fills existing fillable PDFs and adds text where needed. Authoring complex forms with validation is Jotform's strength.
Will my counterparty notice the difference?
No — both produce standard signed PDFs.
Pick the tool that matches your starting material. PDF in hand? Use Flint. Form to build? Use Jotform.
