The AI file format stores data in the AI format. Converting to JPEG produces a image file 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. This makes JPEG the practical choice when the destination system requires it or when the target format offers better compatibility or compression. 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.
