Frequently asked questions
Why convert a font to WOFF?+
WOFF is a compressed web font container — converting a raw TTF/OTF to WOFF before deploying a website cuts the file size roughly in half without changing how the font renders.
Does this change how the font looks or renders?+
No — every glyph outline, hinting instruction, and metric is preserved exactly; only the container format changes.
Is the converted file guaranteed byte-identical to the original if I convert back and forth?+
Every table's data matches exactly, so the font renders identically — but the physical byte layout of a round-tripped file can differ slightly, since the WOFF format doesn't record the original file's internal table order. This has no effect on how the font works.
Does this support WOFF2?+
Not yet — WOFF2 needs a WASM codec, and the only one available couldn't be made to run reliably in the browser. TTF, OTF, and WOFF (v1) are fully supported.
