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（Fujifilm）相机的RAF原文件，记录了镜头捕捉到的每一丝光影细节，是摄影师后期创作的起点。然而，RAF文件体积较大，在日常分享或特定平台使用时常会遇到不便。此时，将RAF转换为JPEG 2000（JP2）格式，便能巧妙地平衡文件大小与图像质量。JP2不仅支持无损压缩，还能更好地保留RAW文件的色彩深度和细节，即便经过压缩，视觉效果依然出色。对于追求高画质同时又注重文件效率的摄影爱好者、设计师乃至普通用户来说，RAF转JP2提供了一个理想的解决方案，让您的精彩瞬间以更灵活、更高效的方式流通。

在中国大陆及周边地区，尤其在移动社交和专业图像处理领域，JP2格式因其在压缩比和图像质量上的优异表现，正逐渐获得更多关注。虽然普及度不及JPG，但其技术优势使其在特定应用场景下成为更优选择，例如在对画质有极致要求的游戏贴图或高分辨率图片展示中。
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.
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.

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.
