FAQ
Is my Nikon NEF 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.
Why does the first conversion take longer?
Nikon NEF requires a WebAssembly decoder that's downloaded once on first use (~1-3MB). It's cached by your browser, so subsequent conversions are instant.
Can I convert multiple files at once?
This tool handles one file at a time. For batch conversions, use the Universal Converter.
