FAQ

Are files uploaded?

V1 prioritizes local processing; disabled cloud mode is clearly labeled.

Are there size limits?

Yes, to protect mobile performance and browser stability.

Can I cancel?

Use reset/cancel to clear current state.

What if conversion fails?

Try a smaller file or another format; disabled cloud fallback will not pretend success.
