Nav About ConvertCraft
ConvertCraft is a free, privacy-first collection of 151 file conversion tools using hybrid processing: local-first where possible, private helpers with auto-delete where needed.
Why Choose ConvertCraft?
Privacy First
Hybrid privacy: many tools run locally in your browser (WebAssembly); heavy tools use private helpers with auto-delete.
Instant Results
Sub-2 second conversions powered by the Nuclear Engine. No waiting for uploads or downloads.
100+ Formats
Support for images, videos, audio, PDFs, and archives. Convert between any format.
Works Everywhere
Runs in any modern browser. No software to install. Works on desktop and mobile.
How It Works
Most heavy lifting is done by WebAssembly (WASM) libraries running in your browser. FFmpeg.wasm processes video and audio. Sharp-wasm handles images. PDF.js manages documents. Advanced features use ConvertCraft's private cloud helpers that auto-delete all files after processing.
