Video Compressor — Shrink Video File Size Online
Compress a video to a smaller file size with three quality presets and an optional resolution cap — processed on your device, never uploaded.
Open toolVideo Resizer
Platforms, portals and projectors all have their favourite dimensions — and a 4K phone video is overkill for almost all of them. This resizer scales a video down to a standard height (1080p, 720p, 480p, 360p) or to a custom width, always preserving the aspect ratio exactly, so circles stay circular and nobody's face gets stretched. It never upscales: ask for 720p on a 480p video and you simply get the video back at its own size, because inventing pixels adds weight, not quality. The resize happens in your browser with the FFmpeg engine — nothing is uploaded.
Choose a file to begin — nothing is uploaded, everything happens on your device.
How to use this tool
- Choose the video — its current dimensions are shown.
- Pick a target height, or enter a custom width.
- Click Resize video.
- Download the resized file (smaller videos are never upscaled).
Worked example
A 720p clip resized to the 480p preset keeps its exact proportions — the width scales in step with the height, so faces and logos never distort.
Frequently asked questions
Will my video get stretched or squashed?
Never. Only one dimension is set — the other is calculated from your video's own aspect ratio (and rounded to an even number, which video codecs require). A vertical phone video resized to '720p' becomes 405×720, still perfectly vertical.
Why won't it upscale my small video?
Upscaling invents pixels by guessing; the file gets bigger and softer, not better. This tool caps at the source size. If a platform demands a minimum resolution, that is the one case where a desktop editor's upscale makes sense — for everything else, original size is the honest maximum.
Does resizing make the file smaller?
Usually, a lot: quarter the pixels (1080p → 540p-equivalent) means roughly a quarter of the picture data. Combined with the quality setting used here, a 1080p clip resized to 720p typically lands at half to a third of its former size.
What is the difference between this and the Video Compressor?
The resizer changes dimensions to a size you choose; the compressor mainly changes the encoding quality (with an optional resolution cap). Use the resizer when a platform specifies dimensions, and the compressor when you just need the file under a size limit.
