FAQ

Is anything uploaded?

No. All processing happens in your browser using JavaScript and WebAssembly. Your files never leave your device.

Why does the first HEIC/RAW conversion take a moment?

Some formats require a WebAssembly decoder that's downloaded once on first use. It's cached by your browser, so subsequent conversions are instant.

Which formats can I convert between?

Any of the 80+ importable formats to any of the 140 exportable ones — see the live Supported Formats list above for the exact, current set. The tool auto-detects your input by its magic bytes, then lets you choose any compatible output format.
