How to reduce video file size
Open Video Compressor when a video file needs a smaller copy. The tool is described for MP4, WebM, MOV, and other video files. It reduces the video locally in your browser, so the file is not uploaded to a server.
- Open Video Compressor.
- Choose the video file that needs a smaller size.
- Review the compression controls shown by Video Compressor.
- Start the compression and use the resulting smaller video file.
When to use Video Compress Tools
Use this category when the requested change is a reduction in video file size. A compressed copy takes less space than the source file, which can help when a file needs to fit a storage location or be shared within a size limit set elsewhere.
The category has one child tool: Video Compressor. Open that page when you already have a video file and want the output to be a smaller video file. The category does not describe this page as a format converter, trimmer, merger, splitter, subtitle tool, or video analyzer.
What Video Compressor handles
Video Compressor is described for these file groups:
- MP4: Choose Video Compressor when an MP4 file needs a smaller copy.
- WebM: Use the same tool for a WebM file that needs compression.
- MOV and other video files: Open Video Compressor when the source is a MOV file or another supported video file.
Choose compression or another video operation
Use Video Compressor for file-size reduction. Use Video Tools when you need to convert, trim, merge, split, burn subtitles into, or analyze a video. The parent page lists those other video operations for cases where compression is not the requested change.
What the local step means
The category description says that video files are reduced locally in your browser, with no upload. The file-size reduction happens in the browser session connected to the page.
That description applies to the compression task. It does not add details about a target file size, output format, compression level, or processing time, so those choices should be read on the Video Compressor page itself.
