One-click presets
Jump straight to 1080P, 720P, 480P or 360P, or type any custom target height.
Scale to 1080P/720P/480P or a custom height, with the width following the original aspect ratio so nothing stretches — fit platforms and shrink size, with key data processed locally and no watermark.

The width is computed from the original aspect ratio — 16:9 stays 16:9, with no stretching or black bars.
Lower resolutions mean visibly smaller files — handy for sharing, uploading and archiving.

Process and download
Drop the video into the Resize Video tool in WUJIEE Video Tools and pick a 1080P/720P/480P preset or type a custom height. Dropping 4K to 1080p usually leaves about 1/4 the size, making transfers and uploads much lighter; processing runs in your browser and is free after signing in.
Resizing changes the pixel dimensions (e.g. 3840×2160 → 1920×1080); compression changes the encoding quality (CRF/bitrate). If you just want a smaller file while keeping the sharp resolution, use the Compress Video tool; if a platform explicitly limits resolution, use this tool. You can stack them: resize first, then compress, for the smallest result.
No. Stretching a video larger can't invent detail and may actually look softer — resizing is usually a downscaling job. For genuinely higher sharpness, you need to fix it at the source when recording.
No distortion: the width is computed from the original aspect ratio, so 16:9 stays 16:9 and the framing never changes. Processing runs with ffmpeg.wasm in your browser — key data is processed locally, and your data is destroyed when you close the page.
