Bypass annoying file size limits

Stop fighting strict upload thresholds. This local video compressor helps you compress video for email, communities, websites, and social media without leaving the browser.

Email: Compress videos for more manageable attachment sizes before sending through Gmail or Outlook.

Communities: Reduce gameplay clips and recordings so they fit tighter upload caps without a separate desktop app.

Social media: Create lighter uploads for TikTok, YouTube, Instagram, and other platforms from the same browser workflow.

Websites: Shrink hero videos and background assets to improve page load speed and keep media lightweight.

Maximum compression, browser-first quality control

You should not have to trade clarity for smaller files. Our video compressor uses browser-native encoding when possible and exposes practical controls when you want to compress video without losing quality.

Smart encoding: WebCodecs is preferred for fast browser-native compression, while FFmpeg is available as a fallback for broader handling.

Dynamic scaling: Downscale large videos to 1080p, 720p, or 480p when a smaller frame size gives you a cleaner size-quality tradeoff.

Exact controls: Use target size, bitrate, frame rate, resolution, and audio settings to tune the final output instead of relying on a black box.

Everything you need in a video compressor

Powerful browser-based tools wrapped in a simple interface, with controls that still respect our local-first product architecture and support a real video compressor online experience.

Universal formats

Handle MP4, MOV, MKV, AVI, WMV, and WebM inputs without sending them to a remote rendering backend.

Browser-first engine selection

The app prefers WebCodecs, then falls back to FFmpeg when a browser or file needs extra compatibility.

Local-first privacy

Files stay on the device during compression, which is a better fit for a pure front-end workflow.

No watermarks

The output is your file, not a branded export layered with product marks or forced sign-up gates.

Responsive interface

The compressor UI is designed to work across desktop and modern mobile browsers with the same settings model.

Custom target sizes

Tell the compressor the file size you want in MB, or switch to advanced settings for finer manual control.
