OpenAnyFile
Our mission
One place that understands every file — rendered instantly and privately, in the browser you already have.
About OpenAnyFile
We built OpenAnyFile for one moment: you double-click a file and your computer shrugs. Nobody should need eleven programs — or an upload to a stranger's server — just to look at a file.
Privacy by architecture
There is no upload endpoint. Your browser parses files with the File API, so we cannot see them even if we wanted to.
How it works
Native browser decoders plus open-source parsers compiled to JavaScript and WebAssembly, all running locally.
Honest about limits
Every format page says what works and what does not, before you open anything.
Why in-browser matters
The files people cannot open are often the ones they least want to hand over: contracts, bank statements, client designs, medical scans. Uploading them to a converter site means trusting a privacy policy you did not read. OpenAnyFile removes that decision — there is nothing to trust us with.
Who builds it
OpenAnyFile is built and maintained by ToolsGuru Group in Islamabad, Pakistan. The format facts (MIME types, signatures, history) are checked against specifications and tested against real files. Contact
Editorial policy
Format facts are checked against primary sources when a page is written. When support changes — a browser adds or drops a codec — the page is updated. We never describe a capability before it works in the viewer.
