Compress Video

The video compressor reduces the file size of any video directly in the browser, without uploading any data to external servers. Processing uses ffmpeg.wasm and runs entirely on your device, ensuring complete privacy.

To compress a video, select the file and choose a quality level: high (best image, moderate size reduction), medium (balanced quality and size), or low (smallest file possible, with noticeable quality loss). The output is always an MP4 file using the H.264 codec, which is widely compatible with all devices and platforms.

The most common use cases include: reducing size before sending via WhatsApp, email, or platforms with file size limits; saving disk space when archiving recordings; preparing videos for websites that have upload size restrictions; or making high-bitrate camera recordings more manageable for quick editing.

The percentage reduction varies significantly depending on the source video. Files recorded by professional cameras in uncompressed or losslessly encoded formats (such as MOV with ProRes codec) typically see much larger reductions than videos already compressed in H.264. If the output is still too large, try the low quality option or consider reducing the resolution with a video editor.
