More free PDF tools
Same quality bar. Still free. Still no upload.
Your files never leave your device
Free to use, with no account, no usage limit and no watermark, because the work runs on your device rather than on our servers.
This is not a promise about how carefully we handle your upload. There is no upload. The file you choose is read into memory by your own browser, processed there, and handed back as a download — the tool has no server component and makes no network request with your data.
- Nothing is stored. We never receive the file, so there is no copy to retain, no retention period to disclose, and nothing to delete on request.
- Nothing is transmitted. No upload endpoint, no analytics payload carrying file contents, no third-party processor.
- You can verify it. Load this page, disconnect from the internet, and use the tool. It still works, because everything it needs is already on your machine.
- Nothing persists after you close the tab. Files are held in page memory only — not in local storage, not in a cache, not in a database.
A note on wording, because it matters: we do not describe these tools as “encrypted.” Encryption protects data that travels to somebody else's computer. Your file does not travel, so there is nothing to encrypt and nothing to intercept — which is a stronger guarantee than encryption, not a weaker one. The page itself is served over HTTPS like the rest of the site.
This makes the tools safe for material you are contractually barred from uploading to third-party services — client footage under NDA, unreleased campaign assets, anything covered by a confidentiality clause.
How it works
1. Drop a filled form
The AcroForm fields and their current values are listed first.
2. Flatten
Each field's appearance is baked into the page and the field is removed.
3. Download the -flat PDF
Values can no longer be edited, and text stays text.
Questions
The fields are still editable after I flatten. Why?
Almost always because the file is XFA, not AcroForm. XFA stores the form in an XML packet that pdf-lib cannot draw into the page. Adobe-era LiveCycle files are the usual source. Re-save as a static PDF from Acrobat, or print to PDF, if you have to lock one of those.
Is flattening the same as printing to PDF?
No. Printing rasterises everything. text becomes pixels. Flattening keeps text as text and only bakes the field appearances into the page stream. The file stays searchable; it just stops being a form.
Can I check the values before I flatten?
Yes. When you drop the file, every AcroForm field is listed with its current value, so you can spot an empty or wrong box before it is locked in. If the file has an XFA packet, the tool warns you first.

Everything on this page works on a file you already have, which is why it costs nothing. Generating something that did not exist (video from a prompt, a voice, a score) runs a model, and that costs credits.
