How this Video Size Reducer Online works

This powerful client-side video compression tool reduces the file size of your videos making them easier to share via email, messaging apps, or social media platforms. By utilizing FFmpeg WebAssembly technology, the entire compression process takes place right in your browser without any server uploads, guaranteeing your videos remain private.

Upload your large video file and choose a compression level: Light, Medium, or Heavy. You also have the option to strip the audio track entirely for maximum size reduction. The tool then optimizes the video encoding, balancing quality and file size according to your selection. A progress bar keeps you informed during the optimization process.

Use this tool to compress 4K phone recordings down to size limits suitable for Discord or WhatsApp, prepare web-optimized videos for faster page loading times, or free up storage space on your devices by archiving compressed versions of your raw footage while maintaining acceptable visual fidelity.
