Convert OTF to WOFF2

The same trip for a font with PostScript outlines. WOFF2 carries an OTF as happily as a TTF — the outlines inside are left alone.

What this does to the font

Nothing is redrawn. The font is wrapped up whole — same glyphs, same spacing, same hinting — only smaller.

Questions

Is my font uploaded anywhere?
No. The conversion runs in this page, on your own computer. No request is made and no copy of the file exists anywhere else, which is what makes it safe to use on a font whose licence forbids redistribution.
Does converting OTF to WOFF2 damage the font?
Nothing is redrawn. The font is wrapped up whole — same glyphs, same spacing, same hinting — only smaller.
Is there a file size limit?
Only what your own browser can hold. A large CJK family of 20 MB converts here; there is no upload to time out.
Can I convert a font I did not make?
Converting a file you already have is not redistribution, and nothing leaves your machine here. What the licence says about using or sharing the result is a separate question, and it is the licence that answers it.
