Video File Size Comparison
Important: This tool creates WebM files through native browser recording, not MP4 files. Compression is not guaranteed to reduce the size of every original video. Encoding follows the video’s playback in real time, so keeping the tab active is recommended. Audio capture depends on browser support, and no video is uploaded to the FileZentra server.
How to Compress Video Online
Upload a compatible video file, choose a compression preset, and adjust the resolution or bitrate if needed. Click Compress Video, preview the result, and download your compressed WebM file.
Lower resolutions and video bitrates often reduce storage requirements, but can also lower visual quality. The amount saved depends on the source video, encoding efficiency and selected settings. Compare the resulting file size with the original before deciding which file to keep.
