Why resize a video by height instead of exact pixels?
Setting only the target height keeps the video's original aspect ratio automatically, so nothing gets stretched or squeezed — the width is calculated to match. This is the safest way to shrink a video for a smaller file, or to raise its resolution to fit a specific player.
The video needs to be re-encoded to change its resolution, which can take longer than a simple trim, but the whole process still runs entirely inside your browser.
Frequently asked questions
Will the video get distorted?
No. Only the height is set directly — the width is calculated automatically to keep the original aspect ratio.
Can I make the video bigger, not just smaller?
Yes, pick a custom height larger than the original, though upscaling won't add real detail beyond the source video's own quality.
