Compress video online without uploading your source file
A video compressor is useful whenever a clip is too large for upload, chat, email, or a quick review workflow. You can reduce video file size while keeping the source video on your device.
The presets cover common creator needs: a balanced social upload, a 1080px wide TikTok/Reels option, a smaller Discord/email option, and a custom bitrate mode. Lower bitrate and smaller width usually create smaller files, while higher settings keep more detail.
If you are preparing source material, pair this compressor with the audio extractor to pull sound from a clip or the final frame extractor to export a still frame for continuation workflows.
Need a source clip first? The existing TikTok downloader and YouTube Shorts downloader can help you save reference videos before you compress, extract, or analyze them.
