How do I clean and sanitize media filenames for web and SEO safety?

Drop files or paste a list of filenames into the sanitizer. The tool automatically removes spaces, illegal characters (` : " / \ | ? *`), emoji glyphs, and converts text to clean kebab-case or snake_case.

Why should filenames be sanitized for web publishing and SEO?

Spaces and special characters in filenames cause ugly URL encoding (`%20`, `%23`) and broken links in web browsers and CDN servers.

Can I convert filenames to lowercase and kebab-case?

Yes. Standardizes filenames like `My Family Photo (1).JPG` into clean SEO-friendly `my-family-photo-1.jpg`.

Does the sanitizer preserve file extensions?

Yes. File extensions are safely isolated, lowercased, and preserved.

Can I batch rename multiple filenames at once?

Yes. Sanitize hundreds of filenames in one click.

Is file sanitization processed locally?

Yes. String regex sanitization runs client-side in browser memory.
