Compress video without uploading it
Big video files are slow to send, hit email and upload limits, and eat storage. This free compressor re-encodes your clip with the efficient H.264 codec to dramatically cut the file size while keeping it perfectly watchable. Everything happens in your browser, so nothing is uploaded.
Choose a quality preset and, if you want an even smaller file, downscale the resolution to 720p or 480p. You will see exactly how much smaller the result is before you download.
How it works
- Drop in a video file.
- Pick a quality preset: High, Balanced, or Smallest.
- Optionally downscale to 720p or 480p.
- Compress, then compare the size savings and download.
Which settings should I use?
- Balanced is the sweet spot for sharing on social or messaging apps.
- Smallest plus 480p is great for email attachments and quick previews.
- High keeps near-original quality while still trimming wasted bitrate.
Is it really free and private?
Completely. There is no account, no watermark, and no upload. The compression runs on your own device with ffmpeg.wasm. When you need to turn one clip into many hook variations, the repli.ac editor picks up where this leaves off.
