Fill in a PDF form's text boxes, checkboxes, radio buttons, dropdowns and lists in your browser, then download it editable or flattened. Works with standard (AcroForm) fields.

Type answers, tick boxes and choose options. Fields are grouped by page.
Leave Flatten off to keep the form editable, or tick it to lock the answers in.
Press Fill and download to save the completed PDF to your device.
Fill PDF Form reads the interactive fields built into a PDF (the AcroForm fields that Acrobat, Word and most form builders create) and shows each one as a normal web form: text boxes and multi-line boxes, checkboxes, radio buttons, dropdowns and selection lists. Fields are grouped by page in reading order and use the form's own tooltips as labels where the PDF has them. Read-only fields are shown but can't be changed.
When you press Fill and download, the values are written into the same fields with pdf-lib, so the result is still a fillable form you can correct later. Tick Flatten after filling and the answers become part of the page instead, so nobody can edit them; that is what many offices ask for when you email a completed form.
Limits: flat or scanned forms have no fields to read, so this tool says so and points you to Edit PDF, where you can type anywhere on the page. Dynamic XFA forms made in Adobe LiveCycle can't be filled in a browser. Signature fields are listed but not signed here. Answers with characters the built-in PDF font can't draw (such as Hindi or Chinese) are saved as field values for the reader to display, and can't be flattened.
Government, bank, school and visa forms often arrive as fillable PDFs, and printing them to fill by hand wastes time and paper. Filling them in a browser tab works on any computer or phone, without installing Acrobat, and the form, which usually holds your name, address and ID numbers, is never uploaded.

The PDF is probably a scan or a flat document that only looks like a form. There are no fields to fill, but you can open it in Edit PDF and add text boxes wherever you need them.
No. The fields are read and filled in your browser, so your personal details stay on your device. Our server only counts runs.
It turns your answers into ordinary page content. The PDF looks the same, but the fields are gone, so nobody can change the answers. Leave it off if you might need to correct something later.
Yes. It works in Safari on iPhone and iPad and in Chrome on Android. The fields show as normal phone inputs, which are easier to use than tapping on a tiny PDF.
No. Dynamic XFA forms need Adobe's own form engine, which browsers don't have. Open those in Adobe Acrobat Reader. Standard AcroForm fields, which most fillable PDFs use, work here.
Yes, but the built-in PDF font can't draw those characters, so the values are saved in the fields and the reader displays them. Acrobat Reader, Chrome and Edge do this. Those answers can't be flattened.
