FAQ

Can I compress YouTube Shorts without an account?

Yes. The Preview compressor works in the browser and does not require an account for local compression.

Will this change my Shorts content?

Compression changes file size and encoding settings, not the edit itself. Always review the exported MP4 before uploading.

Are YouTube Shorts Pro controls live?

No. Advanced controls are Preview roadmap items until server-side entitlement and payment systems are finished.
