TIFFファイルは、その高品質と柔軟性から、グラフィックデザインや出版業界で長らく重宝されてきました。特に、マンガ原稿や高解像度のアートワークの保存において、その非圧縮性や多層構造のサポートは大きな利点となります。しかし、これらのファイルを特定のビジネスアプリケーションやCADシステムで利用する際、またはより軽量な形式での共有が必要な場合、CAL形式への変換が不可欠となることがあります。CAL形式は、主にラスターイメージの表示や編集に特化しており、TIFFとは異なる特性を持っています。この変換ツールは、TIFFの持つ豊かな情報量を損なうことなく、CAL形式の要件に合わせた最適なファイル生成をサポートします。日本のビジネスシーンやクリエイティブな現場で求められる、正確かつ効率的なファイル変換を、ぜひこの機会にご体験ください。
- マンガ原稿のCADシステム連携
- ビジネス文書の図面挿入
- 古い設計図のデジタルアーカイブ化
日本では、特に建設・土木業界や製造業において、CADシステムで扱えるラスター形式としてCALが指定されるケースが未だ多く見られます。TIFFからの変換は、これらの既存システムとの互換性を保つ上で重要な役割を果たします。
About TIFF to CAL (CALS) Conversion
TIFF (introduced 1986) and CAL are both image formats, but they differ in important ways. TIFF is an uncompressed or losslessly compressed format favoured in print, publishing, and professional photography. CAL is a widely used file format.

Your TIFF file is decoded and re-encoded as CAL. The conversion involves 4 steps: (1) your tiff file is uploaded and validated, (2) the file is decoded (parsed into its raw data), (3) the data is re-encoded in cal format, (4) the converted file is ready for download.
CocoConvert's converter handles the entire pipeline server-side using FFmpeg, Sharp, and qpdf — battle-tested libraries used by streaming platforms and enterprise tools. Files are encrypted in transit and deleted within 24 hours.
