ReNamer review
A focused Windows renamer with reusable rule stacks, previews, and a free non-commercial tier.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
ReNamer is a Windows desktop utility for batch-renaming files and folders with ordered, reusable rules. It suits Windows users who need repeatable naming workflows rather than one-off manual edits. Common operations include inserting, removing, replacing, changing case, adjusting extensions, and adding sequential numbers. More advanced workflows can use regular expressions, metadata from audio, photos, documents, videos, and other file types, plus Unicode filename support.
Its strongest feature is the rule-stack approach. Users can combine multiple renaming rules, preview resulting names before applying changes, save named presets, and rename batches of folders as well as files. An undo command can reverse the last renaming operation when possible. The Lite license is free for non-commercial use and allows up to five renaming rules and five presets. Pro costs $29.95 as a one-time license, supports commercial use, removes those limits with unlimited rules and presets, and remains valid indefinitely.
ReNamer is a good fit for Windows users who regularly apply structured naming conventions across files or folders. Regex and metadata-based renaming add depth for media libraries, document collections, and other varied file sets, while Pascal Script in Pro provides custom renaming logic. The main constraints are its Windows-only platform scope, Lite limits, and the commercial-use boundary. Choose Pro when unlimited reusable workflows, commercial use, or Pascal Script matter; choose another option if you need a non-Windows platform.
