Free Online Font Converter

ChangeThisFile supports TTF (TrueType), OTF (OpenType), WOFF (Web Open Font Format), and WOFF2 (Web Open Font Format 2). You can convert between any combination of these four formats.

Both are web font formats, but WOFF2 uses Brotli compression instead of WOFF's zlib compression, resulting in approximately 30% smaller files. WOFF2 is supported by all modern browsers and is the recommended format for web fonts today.

Convert your TTF or OTF desktop font to WOFF2 for modern browsers. Include WOFF as a fallback for older browsers. Go to the TTF to WOFF2 or OTF to WOFF2 converter page, upload your font file, and download the web-optimized version.

Yes. The WOFF2 to TTF converter decompresses the web font back to a standard TrueType font file. This is useful if you have a web font and need to install it as a desktop font.

Yes. Font conversions use Python fonttools on the server. Your font file is uploaded securely, converted, and auto-deleted immediately after processing. Files are never stored or shared.

Yes. The converter preserves all glyph outlines, hinting, kerning pairs, OpenType features (ligatures, alternates, etc.), and font metadata. The conversion changes only the container format, not the font data itself.

For web: Use WOFF2 as the primary format with WOFF as fallback. For desktop: Use OTF if you need advanced OpenType features, otherwise TTF is universally compatible. For maximum compatibility across both web and desktop, maintain both WOFF2 and TTF versions.

Font conversions have a 25MB file size limit (free tier; 500MB on Pro), though most font files are well under 1MB. Very large fonts with thousands of glyphs (like CJK fonts) may be 10-20MB but still well within the limit.
