Local Sandboxed Execution
Your images stay entirely in your browser. XORO Tools uses the client-side FileReader API to convert binary images into strings in-memory. No file is ever sent to our backend server, assuring zero privacy leaks.
Performance Optimization
Embedding Base64 codes directly inside inline HTML/CSS eliminates TCP handshake overhead for tiny files, avoiding visual layout shifts (CLS) on slow connections and improving lighthouse scores.
Best Practices for Base64 Images
- Use GZIP/Brotli Compression: Text-based Base64 strings compress extremely well over server networks. Ensure your hosting provider compresses your CSS/HTML bundles.
- Keep it Tiny: Only convert icons, decorative vectors, or logos that are less than 10KB. Large photos should remain as binary assets to allow browser caching.
