Working with WOFF and WOFF2 Fonts

This guide shows how to load WOFF and WOFF2 web fonts and convert them to other formats such as TTF for desktop use or further processing.

WOFF and WOFF2 are compressed web font containers. FontLoader handles both formats transparently — the format is auto-detected from the binary magic bytes.

Loading WOFF / WOFF2

FontLoader.open() decompresses WOFF and WOFF2 containers automatically and returns a standard Font object with the same metadata and glyph access as any other format.

from aspose_font.loader import FontLoader

woff  = FontLoader.open("MyFont.woff")
woff2 = FontLoader.open("MyFont.woff2")

print(woff.font_family, woff.num_glyphs)

Converting WOFF2 to TTF

FontConverter.convert(font, target) produces a new font object in the target format. Converting WOFF2 to TTF extracts the uncompressed TrueType data for editing or re-packaging.

from aspose_font.loader import FontLoader
from aspose_font.converter import FontConverter

woff2 = FontLoader.open("MyFont.woff2")
ttf = FontConverter.convert(woff2, target_format="ttf")

Tips and Best Practices

WOFF2 uses Brotli compression; FontLoader decompresses automatically
After converting WOFF2 to TTF, apply FontCleaner.clean_for_web() before re-packaging
Use FontSubsetter.subset_for_web() before packaging as WOFF2 for web delivery
