JP2（JPEG 2000）形式は、その優れた圧縮率と画質保持能力から、特に高精細な画像が求められる場面で重宝されてきました。しかし、特定の専門的なグラフィックソフトウェアや、古くからのシステム環境では、VIFF（Tagged Image File Format for Visual Image File Format）形式の方がスムーズに扱える場合があります。VIFFは、柔軟な画像データ表現が可能で、研究機関や一部の産業分野で独自の画像処理フローに組み込まれていることがあります。このページでは、お手持ちのJP2ファイルを、VIFF形式へと手間なく変換する方法をご紹介いたします。漫画原稿の入稿、ビジネス文書のアーカイブ、あるいは特定のレガシーシステムとの連携といった、多岐にわたるニーズにお応えします。
- 漫画・イラストの専門ツール連携
- 企業内システムでの画像互換性確保
- 縦書き文書の画像データ変換
日本では、特に高解像度の漫画原稿や美術品のデジタルアーカイブにおいて、JP2が用いられることがありますが、特定の印刷・DTP環境ではVIFFへの変換が求められるケースも存在します。
About JPEG 2000 to VIFF Conversion
Short answer: yes, you can convert JP2 to VIFF online for free, and quality is well preserved with the right settings. Just upload your .jp2 file to CocoConvert, pick VIFF as the output, and click Convert. The whole process takes seconds.
Now for the details. JP2 (JPEG 2000) offers wavelet-based compression with better quality than JPEG at the same bit rate. VIFF is a widely used file format. Converting between these two formats lets you convert between formats quickly.
Your JP2 file is decoded and re-encoded as VIFF. Converting JP2 to VIFF maintains high quality with CocoConvert's optimised encoder settings.
CocoConvert runs entirely online — no software to install, no account to create. Your files are encrypted during upload (TLS), processed on isolated servers in Germany, and permanently deleted after 24 hours. It works in Chrome, Safari, Firefox, Edge, and all mobile browsers.
Need to convert more than one file? Free users can do 5 per hour. Pro gets 100 per hour with files up to 5 GB each.
