The 7-Zip Archive format uses the LZMA2 algorithm to achieve compression ratios 30-70% better than ZIP, with optional AES-256 encryption. Converting to DEB produces a archive file that stores data in the DEB 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 DEB 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.
