A PDF editor that keeps your files off the network.

PDFluent reads, edits, redacts, and signs PDFs entirely on your machine. No account, no cloud. Crash reports only if you turn them on. The PDF engine is written in Rust.
Free for everyone, including at work. No credit card to download.

What you can do with it

Read heavy files

Open long scans and print-ready artwork. Rendering is native Rust.

Edit text in place

Click a line and rewrite it. Fix a typo in a contract or update a figure without exporting to another tool and back.

Redact for real

Black bars that actually remove the text underneath, not just cover it. The words are gone from the file, which is what GDPR and discovery reviewers check for.

Sign cryptographically

Apply PAdES digital signatures that make tampering detectable. Any change to the document after signing breaks the signature.

Full PDF tools for desktop

The tasks you usually upload a PDF to a website for — merging, splitting, compressing, converting — all run right on your desktop. No upload, no queue.

Merge PDF

Combine several PDFs into one document in the order you choose.

Split PDF

Divide a document by page range to create separate files.

Organize PDF pages

Reorder, rotate, or delete pages without leaving the app.

Compress PDF

Reduce file size.

Password protect PDF

Set a password and restrict permissions on a document.

Add watermark to PDF

Add a text watermark across all pages.

PDF to Word

Convert PDF to Word, Excel, PowerPoint, image, or PDF/A.

Every tool, one line each, checked against the app

Your documents never leave your device

Online PDF tools route your files through their servers. PDFluent does not. Contracts, medical records, tax filings — they stay on disk, where you put them.
No cloud
Every operation runs locally. Nothing is uploaded.
No account
Download and use it. Nothing to sign up for.
Crash reports only if you turn them on
We cannot see your files or how you use them.

Written in Rust, from scratch

The Chromium project reports that around 70% of serious security bugs in Chromium are memory-safety problems [C21, 2026-10-15]. PDFluent is written in Rust, which rules out that class of bug in safe code.

What is still in progress

We would rather tell you the rough edges than hide them.

  • XFA form rendering is experimental. It improves with each release.
  • Editing text in place is in the app and not yet covered by a test, so it is not on the feature list.

Questions

Is it really free?

Yes, for everyone, including commercial use, with no time limit and no account. There is no seat count, no subscription, and no locked features.

Do my files get uploaded anywhere?

No. Every operation runs on your machine. The editor makes no network calls to process a document and has no cloud sync. It sends crash reports only if you turn them on. It works fully offline.

Which platforms are supported?

macOS 11 and later (Intel and Apple Silicon, one universal build) and Windows 10 and later. The macOS build is signed with a Developer ID and notarised by Apple, so it opens without a security workaround.

What is not finished yet?

The desktop editor is generally available since 1.0.0 (2026-09-18) [B45]. XFA form rendering is experimental and improves with each release, and a handful of tools, editing text in place among them, are in the app without a test behind them yet. /editor/features lists only the ones that have one.
