About this tool
This tool does one job and does it entirely on your device. Export form data as JSON or FDF, refill the entire form from JSON, and remove read-only restrictions — all in your browser. Processing runs locally in your browser's memory — the document is never transmitted, and closing the tab clears it completely. The workflow is deliberately short: load the file, choose the options on the page, run the operation, and save the result. Every choice is applied before the file is written, so re-running with different settings takes seconds. Output covers JSON, FDF; Practical limits apply (see the on-page limits); it pairs well with the related tools linked beside this page when one step is not the whole job. Key facts — Processing: runs entirely in your browser, client-side; Access: free with no account required; File limits: see the on-page limits; Privacy: the file never leaves the device.

FAQ
Will my file be uploaded?
No. Everything runs locally in your browser — your file is never uploaded, and closing the page clears it immediately.
Are there any limits?
Supports AcroForm forms only; does not crack encrypted documents; supported output formats include JSON and FDF.
How accurate is the data extraction and export?
The tool directly reads and writes AcroForm field dictionaries and exports values as-is; it does not crack encrypted documents, which must be decrypted first.
Can I process multiple files in bulk?
A single tool page handles one task at a time; for bulk work use the Batch Processing workflow and add this tool as a step to run a whole set at once.
How are results saved, and will the original file be modified?
The original document is untouched; the tool exports standard JSON or FDF data files, and refilling produces a newly populated PDF copy that remains viewable and editable in standard readers.
