About this tool

Flatten a fillable PDF so the values typed into its form fields become permanent page content. After flattening, the filled-in text, checkboxes, dropdown choices and radio selections are drawn onto the pages themselves — they display identically in every viewer, survive printing, and can no longer be edited or accidentally cleared.

Flattening runs entirely in your browser with pdf-lib: your file never leaves your device and nothing is uploaded, which is important because filled forms often contain names, addresses and other personal data. Drop the file, see how many form fields it contains, and download the flattened copy.

This tool targets standard AcroForm fields (the common fillable-PDF format). Non-form annotations such as sticky-note comments are outside its scope, and XFA-based forms (rare, made with older Adobe LiveCycle) are not supported.

Frequently asked questions

What does flattening actually do?
It draws each field's current appearance (the typed text, ticked boxes, selected options) directly onto the page and removes the interactive field, so the data becomes ordinary, uneditable page content.
Is my filled form uploaded anywhere?
No. The form is flattened locally in your browser with pdf-lib — your file never leaves your device.
What if the PDF has no form fields?
The tool tells you right after loading the file. A PDF without AcroForm fields has nothing to flatten, so no download is offered.
Can flattening be undone?
No — that is the point. Keep your original fillable copy if you may need to edit the values later, and share the flattened version.
