MOV is a video format: it packages video and audio in Apple's QuickTime container, which can hold ProRes, H.264, or HEVC tracks. JPEG is a image format that uses lossy DCT compression that permanently discards fine pixel detail to achieve small file sizes, ideal for photographs. 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. Converting between these two formats is common when the source application does not support JPEG natively or when the target platform only accepts JPEG. 1converter processes this conversion server-side using open-source tools. Files are transferred over HTTPS, converted on secure cloud servers, and automatically deleted after 24 hours.
