Compress MP4 and WebM videos

Ideal when a large clip exceeds an upload limit or takes too long to send, especially for websites, email and team chats.

Shrink an MP4 or WebM video to a lighter file that is easier to upload, share and store, while keeping the picture clear and watchable.

How to use

Select an MP4, WebM, MOV, MKV or AVI video from your device.
Pick the output format offered, such as universal MP4 or web WebM.
Start the compression and wait while the video is processed.
Download the compressed file when the operation finishes.
Compare the size and quality before replacing your original file.

Example

You recorded a product demo that is too large for an email attachment. After compression, you get a lighter file that is easier to send, while still keeping the picture clear enough for a quick review.

Limits and formats

The input must match the accepted formats and the maximum size shown in the interface; oversized files will be rejected.
Compression lowers the file size but can also reduce visual detail or smoothness in motion.
Results vary with the source video; an already heavily compressed clip may shrink very little.
Always watch the output before deleting the original file.
Metadata, subtitles or multiple audio tracks may not be preserved.

Where processing happens

Your video is uploaded to YOORfree's compute server, where it is processed in memory without being written to disk on the gateway. The file and its result are kept for at most 15 minutes by default, then deleted; neither the name nor the content is logged, and no third party is involved.

Frequently asked questions

Which video formats can I compress?

The tool accepts MP4, WebM, MOV, MKV and AVI files. You can then choose a universal MP4 output or a web-focused WebM output depending on where you plan to use it.

Will the audio still be there after compression?

The compression aims to produce a watchable video with its soundtrack. The final result depends on the source file and the settings used, so play the output to make sure the sound is acceptable.

Can I compress a very long video?

You must stay within the maximum size allowed by the interface. If your file is too large, shorten it or lower its resolution with another tool before trying again.
