Finding a video compressor that is actually free -- no watermark, no signup wall, no "upgrade to remove branding" upsell -- is surprisingly difficult. Most free online compressors either stamp a watermark on your output, limit you to files under 50MB, or require creating an account.

MiOffice compresses videos entirely in your browser using FFmpeg WebAssembly. No server upload, no watermark, no account. Your video stays on your device throughout the entire process.

Why No Watermark Matters

A watermark on compressed video is a dealbreaker for professional use. Client presentations, social media content, portfolio pieces, and business communications all require clean output. Free tools that add watermarks force you into paid upgrades for basic functionality.

MiOffice will never add watermarks because the processing happens in your browser. There is no server involved, so there is no mechanism to inject branding into your output. The compressed video is exactly what FFmpeg produces -- nothing added, nothing removed except file size.

Frequently Asked Questions

Will compression add a watermark to my video?
No. MiOffice never adds watermarks, logos, or branding to your processed files. The output is a clean compressed video.
How much can I reduce video file size?
Typically 50-90% depending on the source and quality setting. A 350MB iPhone 4K video can compress to 35-70MB at medium quality with barely noticeable visual difference.
Does compression ruin video quality?
At Medium and High settings, the quality difference is barely perceptible. Modern H.264 encoding is extremely efficient. Only at Low quality will you notice visible artifacts.
Can I compress videos for email?
Yes. Set quality to Medium or Low to get under Gmail 25MB limit. A 5-minute 1080p video can compress to under 20MB at medium quality.
Is there a daily limit on compressions?
Supported tools include 5 free on-device uses per day, shared across eligible tools. On compatible devices, guest access needs no sign-in. Signed-in users also get 5 daily eligible on-device uses. AI and cloud processing use credits separately.
