TIF is a image format: it stores data in the TIF format. 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. Some pixel detail is discarded by the target's lossy encoder; quality is configurable via the compression setting. 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.
