The PDF Form Filler and Flattener reads fillable PDF form fields locally in your browser, lets you enter values, and exports a new PDF. It is useful for contracts, applications, expense forms, registration forms, and files prepared for archival submission.

Core Features

Upload one PDF file and detect fillable form fields.
Fill text fields, checkboxes, radio groups, dropdowns, and option lists.
Read original field values and edit fields by name and type.
Export a PDF that keeps editable form fields.
Optionally flatten form fields on export to reduce later field editing.
Process files locally in the browser without uploading PDF content.

Steps

Choose or drag a PDF file into the tool area.
After fields are loaded, fill or edit values in the field list.
Enable flattening if the exported fields should not remain editable.
Generate the PDF and download the new file from the result area.

Field Types

Text fields are for names, addresses, notes, and descriptions.
Checkboxes are for confirmations and selected states.
Radio groups are for choosing one value from multiple options.
Dropdowns are for choosing one preset option.
Option lists are for choosing multiple preset options.
Unsupported fields keep their original values.

Flattening

Flattening turns form fields into static PDF page content. The exported fields usually cannot be edited as form controls afterward. Use it for final archives, external submission, approval handoff, and preventing accidental field changes. Keep flattening disabled when the PDF needs later field edits.

Use Cases

Fill fixed fields before submitting contracts, quotes, and approval forms.
Complete expense forms, registration forms, and application forms.
Freeze form content before scanning workflows or archive delivery.
Create PDF files whose fields are less likely to be changed after export.

Privacy

This tool reads PDFs, fills fields, flattens forms, and generates output files locally in your browser. It does not actively upload the original or exported PDF.
