How to bulk rename files in 3 simple steps
Select your entire batch
Drag a whole folder or select hundreds of files at once. Any mix of images, PDFs, videos, and documents works. All processing stays in your browser with no file size limits.
Set your naming rule once
Pick a preset or write a custom template. The same rule applies to every file in the batch automatically. Use {name}, {date}, {n}, and {ext} placeholders to build any naming convention you need.
Download the renamed batch
Review the before and after table, edit any rows that need adjusting, then download one ZIP containing all renamed files. Export a CSV mapping if you need a record of every old to new filename change.
