Rename Files in ZIP

How to use Rename Files in ZIP

Drop the ZIP onto the dropzone. The tool reads the archive's file index locally and renders every entry in a table. You have two ways to edit paths: a rule that applies across the whole archive, and per-row overrides for one-off tweaks.

The three rule modes cover most cases. Contains does a plain string replacement on every occurrence inside every path — useful for swapping a common word out of many filenames. Prefix only rewrites when a path starts with your pattern, which is the right choice for moving a whole folder (e.g. replacing old-folder/ with new-folder/). Regex uses a JavaScript regular expression with the global flag; you can reference capture groups like $1 in the replacement.

The preview table updates as you type so you can see exactly which paths are about to change and which are unaffected. If a rule produces something you did not want for a specific row, click that row's input and type the path you want — a per-row override wins over the rule. Invalid paths (empty, containing .., colliding with another renamed entry) are flagged inline and block the build button until you resolve them.

When you click build, the file data for every entry is copied from the source ZIP into a new archive with the rewritten path, then re-compressed at the level you picked. Nothing is uploaded — the whole operation runs in your browser tab and the original ZIP on disk is never modified. The result downloads as yourname-renamed.zip.
