Video dimensions
Presets fit your video inside the selected dimensions without cropping, stretching or upscaling. Custom width keeps the original proportions.
Questions
Will this crop a portrait video?
No. Both presets and custom width preserve proportions. Presets do not upscale a smaller video. For a portrait recording, the height limit may determine the final width.
Do my files leave my device?
No. Processing stays in your browser. Download your result before closing or reloading this tab.
Is it free?
Yes. No account, payment or watermark.
Which browsers work best?
Use a recent Chrome, Edge, Firefox or Safari. For video, use short clips and keep this tab open while processing. Older devices may need smaller files.
