About Bulk File Rename

Renaming hundreds of files by hand is slow and error-prone. Our Bulk File Rename tool lets you apply consistent patterns - prefixes, suffixes, numbering, and date stamps - to many files at once, directly in the browser. Files stay on your device; nothing is sent to our servers. Preview the new names before you confirm, then download a ZIP of renamed files or apply changes according to the tool workflow. Ideal for photographers sorting shoots, developers organizing assets, and students batching assignment submissions. Because processing is local, you keep full control of sensitive filenames and folder structures. No account, no limits tied to paid tiers - just a practical utility built for real workflows.
