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.
