What Can Batchio Rename on Your Mac?

Batchio provides 9 composable rule types that you can stack in any order. Each rule transforms filenames independently, and the live preview updates after every change. All 9 rule types are included in the free version.

How Do Batchio's 9 Rule Types Work Together?

Batchio applies rules in sequence from top to bottom. Each rule transforms the filename output of the previous rule. You can reorder rules by dragging, disable individual rules without deleting them, and filter which files each rule applies to by extension, folder, or name pattern.

Rule chaining makes complex renaming operations possible without writing scripts. A photographer might combine Date Insertion (to add the shoot date), EXIF Metadata (to append the camera model), and Numbering (to add a sequence). Each rule processes the filename that the previous rule produced. Our guide on how to batch rename files on Mac walks through the full workflow from start to finish.

Batchio detects naming conflicts before renaming starts. If two files would end up with the same name, a warning icon appears in the preview. You can choose to block the operation, auto number duplicates, or skip conflicting files.

Which Rule Types Does Batchio Include?

How Does Batchio's Live Preview Work?

Batchio shows a two column file list with original names on the left and new names on the right. Every rule change updates the preview instantly with no separate preview button. Changed portions of filenames are highlighted, and conflict warnings appear in real time.

The live preview is the core differentiator that sets Batchio apart from other Mac batch renaming tools. Renamer, Name Mangler, and Better Rename all require you to click a separate preview or apply button. Batchio updates the preview as you type, adjust sliders, or toggle rule options.

For large file sets with 500 or more files, Batchio debounces preview updates to maintain smooth performance. The preview still updates within milliseconds of your last input.

What Does Batchio Pro Add?

Batchio Pro is a one time $4.99 in app purchase that unlocks saved presets, folder automation with watch folders, Finder Quick Action for right click renaming, and Apple Shortcuts integration. All 9 rule types remain free.

Saved presets let you store entire rule chains and reapply them with one click. Batchioincludes built in sample presets like "Clean up downloads" and "Photo organizer" to demonstrate common workflows.

Folder automation watches designated folders for new files and applies a preset automatically when files appear. This works in the background, making it ideal for automating download folder cleanup or organizing files as they arrive from a camera import.
