When compared to ZIP, 7Z is a more advanced format. It offers a better compression ratio than ZIP, allowing for smaller files, which can be more portable and increase ease of sharing. If security is a concern, it's worth noting that 7Z supports a strong AES-256 encryption.
The easiest method to convert ZIP to 7Z is using online tools like uFileTool, which allow quick conversion and even batch processing of selected files. However, if you prefer to use local or desktop tools, using a program like 7-Zip is a convenient choice as well.
The default conversion algorithm for 7Z is LZMA. However, the format can also use other algorithms for compression, including LZMA2, bzip2, and PPMd.
The existence of 7Z as a modern format can also be a limitation it faces. Many older computers and systems can have trouble reading the 7Z format, thus there are compatibility issues. In many cases, it might be necessary to use a software like 7-Zip to read and manage 7Z files.
