FAQ
Quick answers
Is it really free?+
Yes. Morphix is free, has no signup, and no hidden quotas. There's no backend to pay for — everything runs locally.
Where are my files uploaded?+
Nowhere. Every conversion runs inside your browser using WebAssembly. Your files never touch a server.
What's the maximum file size?+
There's no hard cap, but you're limited by your device's memory. Most modern laptops handle files up to ~1GB.
Why is the first video conversion slow?+
We lazy-load FFmpeg (≈30MB) on first use. After that it's cached and conversions start instantly.
