About Video Resizer

This online tool allows you to resize, crop, and rotate video files directly in your browser. Change video dimensions, crop unwanted areas, or rotate videos. Perfect for social media optimization, fixing orientation, or adjusting frame composition. All processing happens locally for complete privacy.

What video formats are supported?

You can upload MP4, WebM, and MOV videos. Output can be in the same format or converted to MP4 or WebM.

What operations can I perform?

You can Resize (change dimensions), Crop (cut frame), or Rotate (90/180/270 degrees, flip). Each operation has specific settings.

Will processing affect video quality?

Using 'Original (Copy)' quality for rotate operations preserves 100% quality. Resize and crop require re-encoding - choose High quality for best results.

What are preset resolutions?

Presets include common sizes: 1080p (1920x1080), 720p (1280x720), 480p (854x480), 360p (640x360), and more. You can also set custom dimensions.

How does crop work?

Specify X/Y position (top-left corner) and width/height of the area to keep. Everything outside this rectangle will be removed.

Can I preview before downloading?

Yes! After processing, you can preview the result before downloading to verify it meets your needs.

Is my video file safe?

Absolutely! All processing happens in your browser using advanced video processing technology. Your video is never uploaded to any server.

How long does processing take?

Processing time depends on operation and video length. Rotation (copy mode) is fast (10-20s). Resize/crop requires re-encoding and may take 30-60s for a 5-minute video.
