FAQ

Should I choose deflate or store?

Choose store when the contents are already compressed — photos, video, PDFs, Office documents — because re-compressing them gains almost nothing and costs time. Choose deflate for plain text, logs and source code, which shrink noticeably.

Why were some file names changed?

A ZIP cannot hold two members with the same name, or they overwrite each other on extraction. When a clash appears it becomes a (2).txt, and the result reports how many names were changed — a silent rename is harder to track down than an error.

Is the folder structure preserved?

When you pick a folder, the relative path is kept (photos/2024/a.jpg). Ticking "keep file names only" flattens everything to the root. When you drag single files from the file system the browser usually gives no path, so only the name is kept.

Are the files uploaded?

No. Packing runs in the browser with the platform CompressionStream and makes no network requests at all; it keeps working offline.
