Bulk ZIP Renamer — Prefix/Suffix, Numbering, Find & Replace, Normalize

Choose ZIP

* Max 20 MB (adjustable)

Basic options Prefix: Suffix:
Add sequence: Start #: Padding: Separator: Position:
Directory structure: Lowercase extensions (JPG→jpg)

Find & Replace (applies to the base filename only) Find: → Replace with: Use regex

* Extension is excluded from this replacement.

Name normalization Convert full-width → half-width (alnum/space, etc.) Spaces: Replace non-ASCII with "_" Case:

On name collisions Auto-append -1, -2… to make unique Abort with error on collision

How to use (3 quick steps)

Choose your ZIP

Upload a .zip file (default limit: 20 MB; adjustable via max_mb).
This tool requires PHP’s ZipArchive to be enabled on the server.

Set rename rules

Prefix / Suffix: Add fixed text before/after the base filename.
Sequence number: Enable auto numbering; choose start value, zero-padding (e.g., 3 → 001), separator, and whether the number goes at the start or end.
Keep directory structure: Keep original folders (recommended) or flatten everything into the root.
Lowercase extensions: Normalize file extensions (e.g., JPG → jpg).
Find & Replace: Replace text in the base filename only (extension excluded). Toggle regex if needed.
Name normalization:
- Convert full-width → half-width (alnum/space).
- Replace spaces with _ or - (or leave as is).
- ASCII-only option to replace non-ASCII with _.
- Force lower/UPPER case.
Collision policy:
- Auto-dedupe: append -1, -2… automatically, or
- Halt on collision (abort if a duplicate name would occur).

Run & download

Click “Rename and create ZIP.”
Review the mapping preview (old path → new path).
Download the renamed ZIP.

What you get (output)

A brand-new ZIP containing files renamed per your rules.
Optional preserved folder structure (or a flattened archive, if chosen).
Consistent extensions (lowercased if selected).
A preview table (up to ~200 items) showing old vs new paths.
Download link to the generated ZIP under wp-content/uploads/zip-rename/.

Notes & caveats

Server requirement: PHP ZipArchive must be enabled; otherwise the tool will show a notice and won’t run.
Access & limits: Default upload cap is 20 MB; raise with max_mb. Private by default; switch to public with require_login=0.
Ordering & numbering: Sequence increments per processed file; padding/position/separator apply exactly as configured.
Find & Replace: Operates on the base filename only. If using regex, escape special characters; invalid patterns are ignored.
Normalization:
- Full-/half-width, whitespace collapse/substitution, ASCII-only, and case transforms apply to the name (not the extension).
- Problematic path characters \ / : * ? " < > | are replaced with _. Leading/trailing spaces and dots are trimmed.
Collisions:
- “Auto-dedupe” keeps processing and appends -1, -2…
- “Halt” stops at the first conflict and reports the offending path.
Encodings & OS quirks: ZIPs can contain names from various encodings; normalization helps portability across Windows/macOS/Linux.
Large archives: Very big or deeply nested ZIPs may take time and memory to process depending on hosting resources. Clean up generated ZIPs when done.
