Frequently Asked Questions
Why should I clean my filenames?
Clean filenames ensure compatibility across different operating systems (Windows, Mac, Linux) and web servers. They also make files easier to search, sort, and manage.
What characters are considered 'invalid'?
Characters like < > : " / \ | ? * are invalid in Windows filenames. Other symbols like spaces, ampersands, and percentages can cause issues in web URLs or script processing.
Can this tool rename my actual files?
No. For security reasons, web browsers cannot directly rename files on your computer. This tool helps you generate the 'clean' names, which you can then use with renaming software or scripts.
What is the best format for web files?
For web development, the gold standard is lowercase letters, numbers, and hyphens (kebab-case) or underscores (snake_case), with no spaces or special symbols.
Is my filename data private?
Yes, 100%. All processing happens locally in your browser. We never see, store, or transmit your filenames to any server.
