File renamer

Give photos, screenshots, PDFs, and project documents consistent names with Little Tagger's free file renamer. Rename multiple files at once, review the original and new filenames side by side, and download the results as a ZIP. Everything runs in your browser, with no software to install.

How to rename multiple files at once

1. Add your files. Drag them onto the tool or select Choose files.
2. Choose your naming rules. Replace text, add text before or after a name, or combine names with numbers and dates. The live preview updates as you make changes.
3. Set the order and download. Sort by name, file type, size, or date modified, or drag rows into your preferred order. Select Save Files to save the renamed copies as a ZIP.

Add numbers before or after filenames

Use Name and Index or Name and Counter to number a batch in the order shown. Choose the starting number and its position, then open Advanced to adjust leading zeros, separators, and increments. For example, a three-digit counter and an underscore before the name can turn photo.jpg into 001_photo.jpg. Leave Custom format empty to keep each original name, or enter a shared name for the whole batch.

Replace text, add dates, and clean up names

Remove an unwanted word with Replace text, add a project prefix or version suffix, or use Name and Date to include a timestamp. Advanced mode also lets you change letter case, trim spaces, remove accents, and use each file's modification date. Duplicate or invalid output names are flagged before you download.
