Frequently asked questions
Is my video uploaded to Toolardo?
No. The conversion runs locally in browser memory.
Can I remove the Toolardo watermark?
Yes. The small watermark is enabled by default but is completely optional and can be turned off before export.
Why can the first run take longer?
The browser downloads the shared FFmpeg WebAssembly engine once and normally caches it for later media tools.
