Local Converter is an independent local file conversion application. Its browser interface connects to installed tools on the same computer.
A browser workspace for local files
Files, pasted text and generated results are processed in this browser. They are not uploaded to a conversion server. Engine downloads can require internet access; large operations depend on the memory and CPU available on this device.
Real conversions and clear limitations
The site uses browser libraries and WebAssembly engines. Each operation must produce a real output; unavailable native-only features are disclosed in the workspace.
Common questions
Do files leave my computer?
Files, pasted text and generated results are processed in this browser. They are not uploaded to a conversion server. Engine downloads can require internet access; large operations depend on the memory and CPU available on this device.
Can I convert files without internet access?
The website and required engine assets must load first. Processing runs on this device; a fresh visit or an uncached engine still requires internet access.
How long can I download completed results?
Results stay in this browser tab until you remove them or reload/close the page. Download anything you want to keep. Saved downloads are independent of the browser workspace.
