About Resize Video
Resize a video to preset widths of 240, 360, 480, 720 or 1080 pixels, or enter custom dimensions. Presets keep the aspect ratio.
- Input
- Use the formats listed in the file chooser. Decoding depends on the selected tool and browser.
- Output
- Download the result in the format shown beside its filename. Batch ZIP is available only where the result area offers it.
- Processing
- The current implementation processes the selected files on this device. Processing libraries, language data or models may be downloaded separately; these resource requests do not require uploading the selected file.
- Limits and behavior
- Presets describe pixel width, not vertical p-resolution. Height follows the source aspect ratio unless custom dimensions disable that option. File capacity depends on device memory and input encoding. Large or unsupported files can fail; encrypted PDFs may need to be unlocked before use. There is no site-wide file-size guarantee.
How to use Resize Video
- Choose a supported file, or add and order files when the tool supports multiple inputs.
- Review the settings, then select Start processing. Wait for the result or a visible error.
- Check the result and download the output. Adjust settings and process again if needed.
