MP4 に DJVUコンバーター — 高速＆無料

The MPEG-4 Part 14 Video format packages H.264 or H.265 video with AAC audio in a container format widely supported across every platform and device. Converting to DJVU produces a document file that stores data in the DJVU format. This conversion changes the file's encoding, compression method, and supported feature set. Metadata such as creation date and embedded colour profiles is preserved where the target format supports it. This makes DJVU the practical choice when the destination system requires it or when the original format is not supported by the target application. 1converter runs this conversion on the server: your file is uploaded encrypted over HTTPS, converted using trusted open-source libraries, and the output is held for 24 hours before automatic deletion.
