ZIP Creator

A ZIP file is a container format: it bundles multiple files into one, and for most file types it also compresses their contents using the DEFLATE algorithm, which looks for repeated byte patterns and stores them more compactly. Text documents, spreadsheets, and uncompressed images typically shrink noticeably inside a ZIP, while files that are already compressed — JPEGs, MP4s, other ZIPs — usually come out close to their original size, since there's little redundant data left to squeeze out.

Bundling files this way is useful whenever you need to move several items as a single unit: attaching a handful of documents to an email without hitting per-file limits, packaging a batch of assets for a client, or preparing multiple files for a web form that only accepts one upload. The archive this tool builds preserves each file's original name, but every file is placed at the root of the archive — files are added individually rather than as a folder, so no directory structure is captured or preserved.
