Why Pre-Compressing Matters
25MB is the most critical file size threshold on the internet—it is the universal upload ceiling for free Discord users, Gmail attachments, Google Workspace, and Microsoft Outlook. VideoReduce optimizes video bitrate to target 24MB, leaving sufficient headroom for email MIME overhead and instant Discord chat embedding.

Frequently Asked Questions
Why 24MB instead of exactly 25MB?
Email servers encode binary attachments with Base64, which adds slight data overhead. Setting 24MB ensures the final email payload remains safely below 25MB.
Can I preserve 1080p resolution under 25MB?
For videos under 2 to 3 minutes, 1080p resolution easily fits inside 25MB with crisp visual fidelity.
Will the video play on mobile phones?
Yes. MP4 with H.264 is supported on 100% of modern iOS, Android, Mac, and Windows devices.
Are my personal files kept private?
Completely private. Processing is performed locally in your browser memory with zero cloud uploads.
