About Merge videos
This tool allows you to merge or append multiple video files into a single continuous video. Simply upload your video files, arrange them in the desired order, and merge them into one file for easy sharing or editing.
- 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
- 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.

- 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.
