FAQ

Is my BMP file uploaded anywhere?

No. All processing happens entirely in your browser using JavaScript and WebAssembly. Your file never leaves your device. Nothing is sent to any server.

What's the maximum file size?

There's no hard limit — it depends on your browser's available memory. Most files up to 50MB convert without issues. Very large files (100MB+) may be slow on older devices.

Can I convert multiple files at once?

This tool handles one file at a time. For batch conversions, use the Universal Converter.
