How to Rename Files in a ZIP OnlineBatch renaming without software — directly in your browser
Manually renaming dozens of files inside a ZIP is tedious. ZipSort lets you do it automatically online — either by organizing files using naming rules, or by renaming them directly (Pro plan).
Two approaches to renaming your files
Sort by naming rules (free)
Organize files into folders based on their prefix, suffix, or extension. Perfect for standardizing a delivery without changing individual file names.
Direct file renaming (Pro)
Rename files in bulk inside the archive: add a prefix or suffix, replace part of the filename, or auto-number your files.
Step-by-step: rename files with ZipSort
Load your ZIP archive
Go to zipsort.app/sorter and import your ZIP. The file is read locally in your browser — nothing is uploaded.
Set your rules
Free plan: create sorting rules by prefix/suffix to organize files into folders. Pro plan: access direct renaming options for batch file rename.
Preview the changes
The real-time preview shows exactly how your files will be renamed or reorganized — before you download anything.
Download the modified ZIP
The new ZIP with your renamed/reorganized files is generated in your browser and downloaded directly — no server involved.
Common use cases
Client deliverables
Standardize filenames before sending a ZIP: add a date, project number, or client code.
Photo shoot
Rename hundreds of RAW or JPEG files by adding a shoot prefix automatically.
Project archive
Normalize naming conventions in an exported repo before sharing it.
Accounting exports
Rename invoices or statements to match your internal naming convention.
Frequently asked questions
Can I rename files without extracting the ZIP first?
Yes. ZipSort reads the ZIP directly in your browser and rebuilds the archive with the new filenames. No manual extraction needed.
Is direct renaming included in the free plan?
Direct file renaming is a Pro feature. The free plan lets you sort by rules (prefix, suffix, extension, keyword) to organize files into folders.
Are my files uploaded to a server?
No. Everything happens in your browser. No file ever leaves your computer.
Is there a file size or count limit?
The free plan allows processing a limited number of files per month. The Pro plan removes this limit and supports batch processing.
