Frequently Asked Questions

What does a video stretcher do?
A video stretcher changes the aspect ratio of your video. You can stretch it to fill a new frame (which may distort the image), crop it to fit a new ratio (which removes edges), or add letterbox/pillarbox bars to fit without distortion.
How do I stretch a video to 16:9?
Upload your video, select 'Stretch' mode, choose the 16:9 Widescreen preset, and click Process. The video will be stretched horizontally to fill the 16:9 frame.
Can I stretch a video without distortion?
Yes. Use 'Crop to Ratio' mode to cut the edges to fit your target ratio, or 'Fit with Bars' to add black bars around the video. Both preserve the original proportions.
How do I stretch a vertical video to horizontal?
Upload your 9:16 vertical video, select Stretch mode, and choose 16:9 Widescreen. This stretches the video horizontally. For better results without distortion, use Crop to Ratio instead.
Is the video stretcher free?
Yes, completely free with no watermark. The tool runs in your browser using WebAssembly — your video never leaves your device.
