See the renames before you make them

Renaming many files at once by a rule — adding a prefix, numbering, replacing text — is powerful but risky if you cannot see the result first. This previews how a batch rename will change your filenames, so you can check before committing.

Enter your filenames and a rename rule to preview the result.

Why previewing matters

Batch renaming is a huge time-saver for organising files — applying a consistent naming scheme, adding sequence numbers, stripping unwanted text, or standardising a messy set of names in one operation instead of one by one. But it is also exactly where mistakes are costly, because a flawed rule applied to hundreds of files makes hundreds of wrong names at once, and undoing that is painful. Previewing is the safeguard: seeing the before-and-after for every file lets you confirm the rule does what you intend, and catch problems like a rule that produces duplicate names, strips too much, or does not handle every case, before any file is actually touched. This turns batch renaming from a risky leap into a controlled operation. Checking the preview first, rather than running the rename and hoping, is the difference between confidently organising a set of files and creating a mess you then have to untangle.
