How to choose the right tool
If: You just need to sort by file type
→ Utilixir or ZipSort — both work client-side and are free.
If: You need rules based on filename patterns (invoice-, -final, contract…)
→ ZipSort is the only option with prefix, suffix, and keyword rules.
If: You want to process many ZIPs at once
→ ZipSort Pro supports batch processing.
If: You need to edit ZIP contents (rename or delete files inside)
→ iLoveZIP — though your files will be uploaded to their servers.
If: Privacy is critical (medical, legal, financial files)
→ ZipSort or ezyZip — both run 100% in-browser with no server upload.
Bottom line
If you need more than simple extension-based sorting — prefix/suffix rules, keyword matching, presets, renaming, or batch processing — ZipSort is the only free online tool that covers all of these. It's also the only one with a real-time preview so you know exactly what the result looks like before downloading.
