Resize Video

What Does the Resize Video Do?

The Resize Video tool changes a video's resolution — downscale 4K to 1080p for smaller files, or set exact dimensions for platform requirements. Pick a preset or type custom width and height, then export.

Lower resolution means dramatically smaller files that upload and stream faster — ideal when 4K detail is not needed. It is also how you meet exact specs: ad platforms and some uploaders reject videos at the wrong dimensions. Resizing runs locally in your browser with no watermark.

How to Use It — Step by Step

1. Upload your video file above.
2. Choose a resolution preset (1080p, 720p, 480p) or enter custom dimensions.
3. Preview the output quality.
4. Download the resized MP4 — free, no watermark.

Popular Uses

• Smaller files: downscale 4K footage for fast uploads.
• Platform specs: match exact dimension requirements.
• Old devices: 720p/480p plays smoothly on low-end phones.
• Email & forms: smaller resolutions fit attachment limits.

Private by Design

Like every tool here, the Resize Video works 100% in your browser. Your files are processed on your own device and never uploaded to any server — which also means it is fast, private, and free to use.
