About OxygenPDF

What OxygenPDF is

OxygenPDF is a toolkit of 67 PDF tools: merging, splitting, compressing, converting to and from Word, Excel and images, OCR, redaction, signing, form filling and page editing among them. Every one of them runs inside your browser. There is no upload step, no queue and no "your file is being processed on our servers" screen, because there is no server doing the processing. The web tools are free and require no account, and the same catalogue ships as a desktop app for macOS, Windows and Linux.

The interface is published in 13 languages. These particular pages — about, contact, terms and privacy — are English-only on purpose, so the facts they state are written down exactly once.

How it works

The PDF engines are shipped to your device as JavaScript and WebAssembly and execute in the browser tab. Your document is read from local disk into that tab's memory, transformed there, and written back out as a download. It is never transmitted to us, so there is nothing for us to store, scan, resell or lose in a breach.

You do not have to take that on faith. Open your browser's network panel before running a tool and watch it: no request carries your file. Disconnect from the internet once the page has loaded and the tools keep working. The desktop app makes the same guarantee structurally, since it does the work offline by design.

Two features are exceptions, and both are things you opt into rather than run into. Signing in stores an email address and a user id with Convex, our authentication provider — that one is described in the Privacy Policy. And Chat with PDF is a cloud feature by construction: the document you hand it is uploaded and indexed on our servers so answers can cite the page they came from. Neither is required to use a PDF tool, and nothing else about the tools changes if you never touch them.

Who builds it

OxygenPDF is built and maintained by Muhammad Habib Rohman, an independent developer working from Indonesia. It is a one-person project rather than a company with a support department, which is worth knowing before you write in: it sets an honest expectation about reply times and about who reads your message. That person is reachable directly, and the channels are listed on the contact page.

How it is funded

The web tools are free and stay free. The project is funded by the desktop app: a one-time purchase, currently $29 during the launch period and $79 afterwards, carrying a 14-day money-back guarantee. There is no subscription, no per-file charge and no upsell wall in the middle of a conversion. Paying unlocks the desktop build, the multi-tab workspace, batch processing and the workflow builder. It does not unlock a web tool that was artificially crippled to sell you the fix.

This matters for a reason unrelated to money. A free tool is paid for somehow, and the usual answer in this category is advertising or data. Selling software is the arrangement that lets the privacy claim above stay true.

What we deliberately do not do

• No account for the web tools. No sign-up wall and no email capture before you are allowed to compress a file.
• No file storage. We do not keep your documents, because they never arrive. There is no retention window to ask about and no "delete my files" button to trust.
• No ad tech. No advertising network, no third-party trackers following you between tools, and no selling of usage data.
• No file-size tax. Processing happens on your own hardware, so the practical limit is your device's memory rather than a tier we invented.
