Compress Video Without Uploading It

Video files are large because they contain many frames plus audio. Uploading those files to a cloud compressor can be slow and may expose private footage.

Fixelium's Video Compressor uses FFmpeg in your browser through WebAssembly. This means common compression work can happen on your device.

When Browser Compression Works Best

Use browser compression for:

• short screen recordings;
• product demo clips;
• social media drafts;
• videos you do not want to upload to another server.

Very large videos may need desktop software because browsers have memory limits.

Tips for Smaller Files

Choose heavier compression for drafts and lighter compression for final assets. If the video does not need sound, use Remove Audio first. If you only need the audio, use Extract Audio.
