What is an SEO filename generator?
A tool that converts any filename into a clean, lowercase, hyphenated, keyword-based slug that follows Google's recommended URL and filename best practices.
What format does it use?
Lowercase letters, numbers, and hyphens between words. No spaces, no underscores, no special characters, and the primary keyword is placed first.
Can I generate filenames in bulk?
Yes. Drop a whole batch of files and the generator produces a unique SEO filename for each one based on the keywords you provide.
Will Google rank my pages higher because of this?
Filenames are one helpful signal, especially for images and downloadable files. Ranking depends on many factors — this tool gives you the cleanest possible filename, not a ranking guarantee.
Is it really free?
