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.
