How it works
- Drop a PDF that contains interactive form fields.
- Every field is listed with its current value: text boxes (including multiline), checkboxes, radio groups, dropdowns, and multi-select lists.
- Fill in your values, and optionally enable "Flatten form" to bake them permanently into the page.
- Download the filled PDF.
What people use it for
- Filling government or visa application forms without printing.
- Completing supplier and HR forms whose values must stay machine-readable.
- Flattening a filled form so recipients cannot alter the answers.
Good to know
- Works with standard AcroForm fields; XFA forms (a rare, legacy Adobe format) are not supported.
- If a PDF has no interactive fields, there is nothing to fill — for those, use Sign PDF or PDF Watermark to place content visually.
- Flattening is one-way: after it, the fields stop being editable form controls.
Frequently asked questions
Why did my PDF show "no form fields"?
The document is a plain (or scanned) PDF without embedded form controls. Only PDFs authored with interactive fields can be filled this way.
Should I flatten the form?
Flatten when the form is final — it prevents further edits and renders identically everywhere. Leave it unflattened if the recipient still needs to change values.
Is my form data private?
Completely — the values you type are written into the PDF by pdf-lib in your browser and never touch a server. That matters, because forms are usually full of personal data.
