Does OTF → WOFF2 lose quality?

The target format compression is neutral (lossless or container-only) - neither degrades nor improves quality.

WOFF2 uses Brotli compression - files are ~30% smaller than WOFF (Zlib). Supported by all modern browsers. Use WOFF2 by default.

Yes - fontforge carries hinting, kerning, ligatures across formats.

Yes - EOT (Embedded OpenType) is Microsoft's format for old IE. Works, but rarely needed in 2026.

No - the converter only changes format. Use FontForge or Glyphs to edit glyphs.

Is the conversion safe?

Yes. Small files convert inside your browser - never uploaded. Larger ones land on our server temporarily and are wiped automatically: 200 MB after 10 min, 100 MB after 20 min, 50 MB after 30 min, smaller after one hour. You can also delete them instantly after download.

Yes - 200 MB max per file. Larger files get rejected for performance and cost reasons.

Do you preserve original quality?

Depends on the pair. Lossy compression (e.g. JPG, MP3) always trims something - we set sensible defaults. Lossless (FLAC, PNG, ZIP) keeps everything 1:1.

Do I need an account?

No. The converter works right away - no signup, no login, no payment.
