Why Nomio Stands Out
While each tool has its place, Nomio offers a unique combination of advantages that make it ideal for modern workflows:
1. Universal Accessibility
Unlike platform-specific tools, it works everywhere—Windows, macOS, Linux, ChromeOS. You can even use it on a Chromebook or tablet if needed.
2. Zero Commitment
No installation means no disk space used, no system changes, no update management. Visit the website, rename your files, done.
3. Privacy by Design
Your files never leave your computer. Unlike cloud-based solutions that upload your files to servers, all processing happens in your browser.
4. Modern Technology
Built with modern web standards (File System Access API), it provides a native-like experience with the convenience of web access.
5. Three Powerful Modes
Numbering Mode:
- Sequential numbering with custom formats
- Roman numerals, zero-padding, custom start values
- Multiple numbering styles (Arabic, Roman, Chinese)
- Position control (prefix, suffix, insert)
Replacing Mode:
- Simple find and replace
- Case-sensitive or insensitive
- Replace all or first occurrence
- Regular expression support
Scripting Mode:
- JavaScript-based for unlimited flexibility
- Access to file properties (name, extension, size, date)
- Complex logic and transformations
- Examples provided for common tasks
6. Continuous Improvement
As a web application, improvements and new features are automatically available to all users without any action needed.
