How it works
Three steps, and that is the whole app.
Drop a PDF
It opens right in your browser. Nothing is uploaded.
It finds the blanks
Every empty line and box becomes a fillable field, even on a flat PDF with no form.
Fill and download
Type your answers or let AI fill them, then download the finished form.
Your file never leaves your device.
Blanq opens and edits your PDF right here in the browser. Nothing is uploaded, nothing is stored, nothing touches a server.
How your data is handled →Questions
Is Blanq free?

Do my files get uploaded?
No. Blanq opens and edits your PDF entirely in your browser, so the file never leaves your device or touches a server.
Can I fill a PDF that has no form fields?
