• Use WOFF2 for web — it has the best compression and browser support
• Keep TTF as a fallback for older browsers
• Font subsetting (removing unused glyphs) should be done before conversion for optimal file size
• WOFF/WOFF2 files contain the same font data, just in a web-optimized container

Conversion failed: The font file may be corrupted or in an unsupported variant.
No preview: Some font formats may not render a preview if the browser can't decode the font data.
Output larger than input: This can happen when converting from WOFF2 (compressed) to TTF (uncompressed).
