Why Choose Our Video Compressor?
Unlike other online video compressors, our tool runs entirely in your browser. Your videos are never uploaded to any server, ensuring complete privacy and security. There are no file size limits, no watermarks added, and no sign-ups required. The entire process happens locally on your device using the MediaRecorder API and client-side JavaScript.
What is the Best Codec for Video Compression?
VP9 offers the best compression ratio, typically achieving 40-60% size reduction with good quality. It is YouTube's preferred codec. H.264 is the most compatible codec, working on virtually all devices and platforms, but produces slightly larger files. VP8 is a middle ground with decent compression and good compatibility. For most users, we recommend VP9 for the best balance of quality and file size.

What video formats are supported?

Can I compress multiple videos at once?
Yes, our Video Compressor supports batch processing. Drop multiple video files and they will all be compressed with the same settings in sequence.
How do I compress video to a specific file size?
Switch the Target Mode to 'File Size' and enter your desired size in MB. The tool will calculate the required bitrate automatically to hit that target.
What is the best video codec for compression?
VP9 offers the best compression ratio (smallest files) but takes longer to encode. H.264 is faster and more compatible with older devices. VP8 is a middle ground. We recommend VP9 for best results.
Can I trim video while compressing?
Yes, switch to the Trim tab and set start/end times. The compressor will only process the trimmed portion, which also reduces the output file size.
How much can I compress a video?
Compression results depend on the original video. With VP9 codec, you can typically achieve 40-60% size reduction. Using lower resolution (720p) and bitrate settings can reduce size even further.
