Frequently Asked Questions

Can my browser compress and convert videos without cloud servers?

Yes! ImgZero utilizes modern WebAssembly-compiled video codec engines running in background Web Workers. Your computer's multi-core CPU handles frame extraction and re-encoding locally in memory.

Are any watermarks added to my exported videos?

Never. All video tools produce 100% clean video files without watermarks, branding, or artificial quality restrictions.

Is there any file duration limit or paywall?

No. ImgZero is completely free and unrestricted. Performance depends solely on your computer's local hardware capabilities.
