# About Local Converter > Browser-only file conversion. Selected files are processed on this device and are not uploaded to a conversion server. Source: https://localconverter.tech/about 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. ## 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. ## Related information - [All tools and conversion pairs](https://localconverter.tech/tools.md) - [Supported file formats](https://localconverter.tech/formats.md) - [How local conversion works](https://localconverter.tech/how-it-works.md) - [File privacy and temporary storage](https://localconverter.tech/privacy.md) - [Local processing security](https://localconverter.tech/security.md) - [Terms of use](https://localconverter.tech/terms.md) - [Conversion help](https://localconverter.tech/help.md)
