About Resize Video
Resize Video changes resolution so clips fit platform limits, smaller screens, or bandwidth budgets.
Upload the video, choose the target size, and download the result. Keeping aspect ratio avoids stretched faces and warped graphics when the control is available.
Use it before uploading to sites with max dimension rules or when a lower resolution is enough for preview links.
Example workflow
Reduce a large clip to a smaller resolution for a preview or delivery requirement. Retaining the aspect ratio avoids distortion; resizing is different from choosing a crop.
Output checks and limits
Accepted inputs: MP4, MOV, MKV, AVI, WEBM, M4V. The current processing duration limit is 30 minutes. The upload size shown for your plan also applies; codec compatibility and processing time can still limit a job. Check playback, duration and sound in the downloaded file before deleting the original.
Benefits of Resize Video
Frequently asked questions
Will resize crop the video?
Scaling changes dimensions; it is not the same as a manual crop tool. Use a crop workflow if you need to reframe.
Does smaller resolution always mean smaller file size?
Often yes, but bitrate settings also matter. Compression tools can shrink further after resize.
What inputs are supported?
Common video containers listed on the tool page within the upload limit.
