Batch File Renamer – Rename Hundreds of Files with Custom Patterns
Manually renaming a folder of 200 photos one by one takes hours. This batch renamer applies naming rules to your entire file selection in seconds. Define a custom prefix, choose between prefix-only, suffix-only, or clean rename modes, preview the results before downloading, and get all renamed files in a ready-to-use ZIP package. Ideal for photographers renaming shoot archives, developers organizing assets, and content teams standardizing media libraries.
The tool reads files locally using the browser File API — no actual file content is modified, only the filename metadata used when the file is created for download. Your files never leave your device. Supports images, PDFs, documents, and any file type — the renamer is format-agnostic.
- Prefix mode — Adds your custom text before the original filename
- Suffix mode — Appends text after the original filename (before the extension)
- Clean rename — Replaces the original name entirely with your custom prefix + sequential number
