Frequently Asked Questions
Is this safe and private?
Yes, completely. This tool runs entirely in your browser using WebAssembly. Your files never leave your computer and are not uploaded to any server. Your data is 100% private.
Why does the engine take a moment to load?
The first time you use the converter, your browser downloads a compiled WebAssembly binary containing the FFmpeg processing core (~30MB). Once loaded, it runs directly on your local CPU.
Are there any file size limits?
Browser WebAssembly environments are limited by standard sandboxed memory limits (typically 2GB maximum file sizes). It is highly optimized for short video clips, webinars, lectures, or music clips, but may fail for full-length 4K movies.
