Upload an MP4, MOV, AVI, MKV, WMV, FLV, WEBM, or other supported video from your device.
Adjust the quality slider (CRF). Lower values keep more detail; higher values create a smaller file.
Click Compress. Download the smaller video when processing finishes. Each file stays available for up to 5 downloads.
Balance size and detail with CRF controls so clips stay watchable on phones, browsers, and social apps after compression.
Compress video online on Windows, Mac, Linux, or mobile. No desktop install required.
Upload multiple clips within plan limits, compress in one job, and download each result when ready.
Modern devices and browsers widely support H.264. H.265 (HEVC) can shrink high-resolution footage further when the destination supports it. This compressor optimizes everyday MP4-friendly output for email, WhatsApp, and web uploads.
Compressed files play in major browsers and players. If a clip fails on an older device, open it in VLC or re-compress with a slightly lower CRF (higher quality). Common inputs include MP4, MOV, AVI, MKV, WMV, FLV, and WEBM.
You can shrink a video by trading a little quality, capping bitrate-related settings, or starting from a more efficient encode. Use the quality slider on this page as the main control.
CRF keeps perceived quality roughly constant across frames. Lower CRF = sharper picture and a larger file; higher CRF = smaller file. Around 23 is a solid default for social and email clips.
If the estimate is still too large, raise CRF a step or two, compress again, and check playback on your phone before sending.
Downsizing 4K to 1080p when the audience watches on phones often saves more space than heavy quality cuts alone. Prefer keeping resolution if the video will be projected or edited further.
Some detail is traded for a smaller file. A balanced CRF (around 23) usually keeps talking-head and social clips clear on phones while cutting size. Use a lower CRF when you need sharper detail.
Common formats such as MP4, MOV, AVI, MKV, WMV, FLV, and WEBM are supported. Output is optimized for everyday playback on phones, browsers, and social apps.
Upload the clip, raise compression slightly if the estimate is still large, then compress and download. Smaller files upload faster and pass more size limits.
Yes. Upload a batch within the plan limits shown on the page, compress them in one job, and download each result.
