Fill PDF form in your browser

Many PDF forms have fields built in: text boxes, checkboxes, radio buttons and drop-down lists. OnePDF lists every field in the side panel, so a long form can be filled from top to bottom without hunting for the next box, and saves the answers in the form's own fields.

When you are done, flatten the form to make the answers part of the page, so nobody can change them. A form that is only a printed page with lines on it can be filled with Add text, and signed with Sign PDF.

Why use OnePDF to fill in a PDF form

  • The form's own fields

    Text fields, checkboxes, radio buttons and drop-down lists are filled as the form defines them.

  • No fields? Type anyway

    For a form that is only a printed page, use Add text to type on the lines.

  • Flatten when done

    Make the answers part of the page so nobody can change them.

Questions about Fill PDF form

What if my PDF form has no fillable fields?

Use Add text to type anywhere on the page, and Sign to add your signature.

Can I sign the form too?

Yes. Draw your signature, place a signature image, or sign with a certificate from the Sign page.

Is my form uploaded?

Not unless you sign in. Signed out, your file is opened by OnePDF inside your browser, on your own device, and is not uploaded to any server. Signed in with a TensorActivity account, the files you open are also saved to your account, encrypted, so they are there on every device you sign in to.
