OTF（OpenType Font）は、その表現力の高さからデザインや印刷の分野で広く愛用されてきました。特に日本語フォントでは、複雑な漢字やかな文字の美しい表示、そして縦書きへの対応が不可欠であり、OTFはその要件を満たす強力なフォーマットです。しかし、ウェブサイトで利用する際には、ファイルの容量が大きく、読み込み速度に影響を与えるという課題がありました。そこで登場するのが、ウェブフォントに特化し、高い圧縮率を誇るWOFF2（Web Open Font Format 2.0）です。この変換ツールは、長年培われてきたOTFの美しい文字表現を損なうことなく、ウェブ環境に最適化されたWOFF2へと変換します。あなたのウェブサイトで、日本の繊細なタイポグラフィを軽快に、そして美しく表示するための第一歩を、ぜひここから踏み出してください。
