How to convert OTF to WOFF
- Add your .OTF file - drop it in the box above or click to browse.
- Convert it to .WOFF in a few seconds.
- Download your new .WOFF file.
What to expect
- The conversion is lossless: all glyph outlines, OpenType layout tables (ligatures, kerning, small caps), and Unicode mappings are preserved exactly.
- WOFF2 produces files roughly 30% smaller using Brotli compression; keep
.woffonly as a fallback for Internet Explorer 9-11. - Check the font license before embedding: the
fsTypefield in the OS/2 table may restrict web use or redistribution of certain fonts.
Frequently asked questions
Is converting OTF to WOFF lossless?
Yes - WOFF wraps the same sfnt data as OTF with compression; glyph shapes, OpenType features, and kerning are all unchanged.
Should I use WOFF or WOFF2 for my website?
WOFF2 in most cases - it is smaller and supported by every browser since 2016; add a
.woff fallback only if you need IE9-11 support.Can I convert any OTF font?
Not always - some fonts restrict web embedding via the
fsType license flag; check the font's license before publishing online.Do OpenType features like ligatures survive the conversion?
Yes - the GSUB and GPOS layout tables pass through unchanged, so ligatures, small caps, and kerning all work in the browser.
