Compress a video and compare the actual file size
Create a smaller working copy by choosing a video bitrate and maximum output edge. Compare the actual size and preview before downloading. Processing stays on your device, with a choice to preserve the primary audio track or deliberately mute the result.
Choose a video to get started
Up to 100 MiB, 120 seconds, 2,073,600 pixels per frame and 3840 pixels per edge.
Your video stays on your device. This tool re-encodes video without AI. Subtitles, additional audio tracks, and original metadata are not preserved. Check playback in your destination app.
How to compare a video compression result
Choose a compatible source up to 100 MiB, 120 seconds, 2,073,600 pixels per frame and a 3840-pixel maximum edge. A 1920 × 1080 video fits the pixel limit. Start with the default 1280-pixel output edge and 2 Mbps video bitrate. Choose Auto, MP4 or WebM, then process the clip. Review its actual output dimensions, byte size and size change before downloading. You can cancel an export while it is running.
- Choose a maximum edge suited to the screen or destination where the video will appear.
- Check motion, small text, gradients and the soundtrack in the output preview.
- Compare the downloaded file in your intended player or editor before replacing a working copy.
Balance output dimensions and video bitrate
Choose original dimensions or a maximum edge of 1920, 1280, 854 or 640 pixels. The compressor preserves proportions and only reduces dimensions; it does not enlarge smaller sources. Video bitrate is adjustable from 0.25 to 12 Mbps. Lower settings can reduce bytes but also blur texture or create blocks during movement. At 2 Mbps, 30 seconds of video is about 7.5 MB before audio and container overhead; the actual encoded file may differ.
Choose a supported format and audio behavior
Auto selects an available export workflow. MP4 uses AVC video; WebM uses an available VP9 or VP8 encoder. Browser and operating-system codec support determine which exports can run. Choose to preserve the primary audio track or intentionally mute the result. Unsupported audio produces an explicit error when preservation is selected. Additional audio tracks, subtitles and original metadata are not retained in the re-encoded output.
Use the actual export size to decide whether compression helped
The estimate is a planning aid, not a target file size. A source already encoded at a lower bitrate can become larger, and container overhead or retained audio adds bytes beyond the video estimate. Check the actual size and savings or increase reported for the finished result. Try a lower bitrate or smaller edge only if the preview remains useful. This tool does not run AI, repair blur or guarantee a smaller file.
video compressor questions and answers
Can I compress a video to exactly 10 MB?
This compressor does not automatically target an exact byte size. Choose a video bitrate and maximum edge, review the estimate, then check the actual exported size. Audio, container overhead and the encoder’s behavior can make the final result differ from the estimate.
Why is my compressed video larger than the source?
The source may already use a more efficient codec or lower bitrate. Re-encoding with a higher video bitrate can add bytes. Compare the actual result, try a lower setting if its appearance remains acceptable, or keep the original.
Does this video compressor preserve sound?
It can preserve the primary audio track when the source and browser support the required audio workflow. Unsupported audio causes an explicit error when preservation is selected. You can choose mute to export deliberately without sound. Additional audio tracks are not retained.
Can I compress 1080p video or footage longer than 30 seconds?
Yes, within this tool’s 100 MiB, 120-second, 2,073,600-pixel and 3840-pixel-edge limits. It is a separate re-encoding tool. AI video enhancement still accepts only 30 seconds and 720p-equivalent input; compression does not expand those AI limits.
Does compression improve video quality?
No. It changes encoding settings and can reduce resolution to suit a file-size or delivery need. Lossy re-encoding can remove detail. For AI enlargement, use the separate video upscaler with an eligible source and compare its result.
