What is ZIP?
ZIP is the universal container for shipping a directory as a single download. Because it preserves the folder structure, two archives of the same project can be compared file by file to see exactly what was added, removed or modified.

Folder Diff Runs in your browser — no upload
Overview
What you need to know
Where ZIP works well
Preserves folder structure; Built into every operating system; Lossless compression. Those properties explain its typical habitat: Project and build hand-off, Bulk downloads, Backup snapshots. If your requirement matches one of those, ZIP is almost certainly the right default rather than a compromise.
Where ZIP struggles
No format is universal. Weak legacy encryption; No delta updates; Must be extracted before use. None of these are reasons to avoid ZIP outright — they are the specific cases where reaching for a different format saves you time later.
