Quick answers about how this tool works.
Yes! The API features full multi-byte UTF-8 Unicode parsing. Names in Devanagari (Hindi), Arabic, Cyrillic, Chinese, and other scripts will generate accurate initials.
You can request vector SVG (format=svg), crisp PNG (format=png), or compressed WebP (format=webp) images directly from the GET /api/avatar endpoint.
Yes! You can pass the API URL as the default fallback parameter (d=) in Gravatar requests or set it in your frontend onerror image handler.
You can send a POST request to /api/avatar/bulk with a JSON array or CSV file of user names. The tool will render all avatars and return a downloadable ZIP file archive.
No API keys or signup required! Generous IP throttling is in place so your application can render user avatars dynamically.
