RAF vs JP2 — Comparison & Free Converter
Fast, instant RAF (FUJIFILM) to JPEG 2000 conversion. No signup required. Just drop your .raf file and get .jp2 in seconds.
Batch Settings
HDR data will be tone-mapped
Your RAF file may contain HDR (High Dynamic Range) data. JP2 only supports standard dynamic range (SDR). Highlights and shadows will be compressed to fit the 8-bit range — subtle detail in very bright or dark areas may be lost.
Some metadata may not survive
Your RAF file may contain MakerNote metadata. JP2 has limited or no support for these metadata types. Location data (GPS), camera settings, and color profiles may be stripped during conversion.
富士フイルムのカメラが捉えるRAFファイル。その豊かな階調と細やかな色彩は、写真愛好家にとってかけがえのないものです。しかし、ウェブでの共有やビジネス文書への組み込み、あるいは特定のアーカイブ要件を満たす際には、より汎用性の高い形式が求められることも少なくありません。そこで注目されるのが、高圧縮率と優れた画質を両立するJP2（JPEG 2000）形式です。このページでは、大切なRAFファイルを、日本のデジタル環境に最適化されたJP2へとスムーズに変換する方法をご紹介します。元の画像の美しさを損なうことなく、より幅広いシーンで活用するための第一歩を、ぜひここから始めてください。特に、繊細な表現が求められる場面で、その真価を発揮することでしょう。

日本では、縦書き文書との親和性や、印字品質を重視するビジネス慣習から、画像形式の選択においても高画質とファイルサイズのバランスが特に重要視される傾向があります。
About RAF (FUJIFILM) to JPEG 2000 Conversion
RAF or JP2 — which format should you use? The answer depends on your needs. Here's a quick breakdown.
RAF is Fujifilm's RAW photo format, preserving the X-Trans or Bayer sensor data. It has limited platform support. JP2 (JPEG 2000) offers wavelet-based compression with better quality than JPEG at the same bit rate. It has limited platform support.
Full Name: RAF uses Fujifilm RAW, while JP2 uses JPEG 2000. Compression: RAF uses Lossless, while JP2 uses Lossy & Lossless. Transparency: RAF uses No, while JP2 uses Yes.
So when should you convert RAF to JP2? This conversion is ideal when you When you specifically need a JP2 file for your workflow. This conversion helps you convert between formats quickly.

What Happens When You Convert RAF (FUJIFILM) to JPEG 2000
Your RAF image is decoded into raw pixel data, then re-encoded as JP2.
Your RAF file is decoded — the compressed/stored pixel data is expanded into raw RGB pixels
HDR data is tone-mapped to standard dynamic range (8-bit per channel)
Pixels are re-encoded using JPEG 2000's lossless compression
Metadata (EXIF, ICC profiles) is transferred where JP2 supports it
The JP2 file is saved and ready for download

Frequently Asked Questions
Should I use RAF or JP2?
It depends on your goal. RAF preserves full quality. JP2 preserves full quality. Choose based on whether file size or quality matters more for your use case.
Is JP2 higher quality than RAF?
Not necessarily. Your RAF file may contain HDR (High Dynamic Range) data. JP2 only supports standard dynamic range (SDR). Highlights and shadows will be compressed to fit the 8-bit range — subtle detail in very bright or dark areas may be lost. Quality depends on the compression type and settings, not just the format name.
Can I convert RAF to JP2 on Mac and Windows?
Yes. CocoConvert is a web-based tool that works in all modern browsers — Chrome, Safari, Firefox, Edge — on any operating system including macOS, Windows, Linux, iOS, and Android.
Is CocoConvert free for RAF to JP2?
Yes. Free users get 5 conversions per hour (250 MB each). Pro subscribers unlock 100 files per hour, 5 GB per file, and priority processing.
What tools does CocoConvert use for RAF to JP2?
CocoConvert uses FFmpeg for audio/video, Sharp for images, and qpdf for documents — the same open-source libraries used by Netflix, YouTube, and major enterprise platforms.
