How does bulk file renaming work online?

Upload multiple files, choose naming pattern (sequential numbers, custom prefix/suffix, find-replace text), preview new names, and download renamed files in ZIP. Renames 100s of files instantly. Verify by checking preview list before downloading.

What file types can I bulk rename?

Rename any file type: images (JPG, PNG, WEBP), documents (PDF, DOCX, TXT), videos (MP4, AVI), archives (ZIP, RAR). File content unchanged—only filenames modified. Perfect for organizing photos, documents, downloads, or project files.

Can I add sequential numbers or dates to filenames?

Yes! Add sequential numbers (001, 002), timestamps, dates (YYYY-MM-DD), custom prefixes ("vacation_"), or suffixes ("_backup"). Combine patterns for complex naming like "Photo_2026_001.jpg". Preview changes before applying—verify numbering is correct.

Is bulk file rename safe and reversible?

Original files remain unchanged. All processing happens in browser—files never uploaded to servers. Download ZIP contains renamed copies. Keep originals as backup. Verify in preview before downloading. If mistakes occur, re-upload and rename again.

Why use bulk rename instead of manual renaming?

Saves hours when organizing 100s of files, ensures consistent naming conventions, prevents typos, applies patterns automatically, increases productivity. Manual renaming is error-prone and time-consuming. Ideal for photographers, content managers, data organizers.
