How to use the Video Compressor tool
- Drop a video (MP4, MOV, WebM, MKV, AVI and more) into the box above.
- Choose how much to compress — Light, Balanced or Strong — or pick a target size such as 16 MB for WhatsApp or 25 MB for email.
- Optionally lower the resolution or remove the sound for an even smaller file.
- Click Compress video, compare the sizes and download your MP4.
Smaller videos, same moments
Phone videos are often hundreds of megabytes — too big for WhatsApp, email attachments or website uploads. The compressor re-encodes your video with the efficient H.264 codec, which usually cuts the size by 50–90% while keeping it clear and smooth.
Choose a quality level, or enter the exact size you need and the bitrate is calculated for you. Lowering the resolution to 720p or 480p shrinks the file even more and is ideal for phone screens.
Everything happens inside your browser, so private videos are never uploaded.
Video Compressor: free, fast and private
Compress MP4, MOV and other videos to a smaller file size — pick a quality level or an exact target size — for free, on any device. Whether you are working with phone recordings, screen captures and clips, the Video Compressor tool gets it done in seconds without installing anything.
Because Video Compressor runs locally in your browser, it is fast and private at the same time — there is no upload to wait for and no copy of your data left behind.
