VIDEO TOOLSCompress Video Files Online
Reduce a video file when you need a smaller copy for sharing, storage or an upload limit. Select a browser-supported video, choose the available compression settings and export the processed version without installing a desktop editor.
The final size depends on factors such as duration, resolution, frame rate, source codec and the compression settings used. Smaller files generally require a trade-off in visual or audio quality, so preview the result when quality matters. A short clip may already be efficiently compressed and show only a modest reduction, while a high-resolution or high-bitrate source can offer more room to shrink. Browser and device capabilities also affect which formats can be decoded and encoded.
Processing is performed locally in your browser rather than by uploading the source video to a remote processing server. For the best balance, avoid repeatedly recompressing the same file. If you only need a shorter section, use the Video Cutter first; removing unnecessary footage can reduce size without compressing the remaining frames more aggressively.
Reducing video size for sharing
Reduce video dimensions or file size in the browser using the options available on this page. Compression can make sharing and uploading easier, but smaller files usually require a trade-off between resolution, bitrate, processing time and visible quality.
When this tool is useful
Compression reduces file size by changing bitrate, resolution, codec settings or a combination of them. It is useful for email attachments, uploads, messaging and storage, but a smaller file always involves a trade-off between size, processing time and visual quality.
Practical limits and quality checks
Start with moderate compression. Text, screen recordings and highly detailed scenes can react differently from simple talking-head footage. Keep the source file until you have checked the compressed result on the device or platform where it will actually be viewed.
Privacy and responsible use
Compression works on the video you choose in the browser. Keep the original and use only footage you are authorised to process, because reducing file size deliberately trades some data or resolution for a smaller output.
Frequently asked questions
Why can video processing take longer than expected?
Yes, aggressive compression can reduce detail, introduce blockiness or soften motion. Start with a moderate setting, compare the export at full size and increase compression only when the smaller file is worth the visual trade-off.
Will editing reduce video quality?
Video compression is computationally intensive: resolution, frame rate, duration and codec all affect speed. A plugged-in desktop or laptop with free memory generally handles large files more reliably than a phone browser.
