About this tool
Fill in an interactive PDF form's text fields, checkboxes, and dropdowns, then add your signature before downloading — all processed locally in your browser, without uploading the form to a server.
Limits and edge cases
- Only fields already built into the PDF as an interactive form are detected — a scanned form with no real form fields has nothing for this tool to find; use Sign PDF to place text or a signature freely instead.
- Filled-in field values remain editable after download unless the form is flattened, since the underlying AcroForm fields are kept live by default.
- A password-protected PDF needs to be unlocked first, since detecting and writing to form fields requires opening the file directly.
- Complex forms with scripted field behavior (auto-calculating totals, conditional fields) may not trigger those scripts here, since this tool fills values without executing a PDF's embedded JavaScript.
Compared with tools that upload your file
iLovePDF, Smallpdf and PDF24 all offer this kind of job, and the online ones upload your file to their servers to do it. Here the work happens in this tab instead.
