Quality reduction ahead
RAF is lossless, meaning every bit of data is preserved. HEIC uses lossy compression — some data is permanently discarded to reduce file size. At high quality settings the difference is usually imperceptible, but the original data cannot be recovered.
Some metadata may not survive
Your RAF file may contain MakerNote metadata. HEIC has limited or no support for these metadata types. Location data (GPS), camera settings, and color profiles may be stripped during conversion.
Color depth reduction: 14-bit → 10-bit
RAF stores up to 14 bits per channel, but HEIC supports only 10 bits. You may notice banding in smooth gradients (like sky or skin tones) where subtle color transitions are lost.
What compression artifacts to expect
HEIC lossy compression can produce blurring and occasional color shifts at high compression. At the high quality settings CocoConvert uses by default, these are usually invisible to the eye. Lower quality settings trade visual fidelity for smaller file sizes.
富士フイルムのカメラが捉えた、あの息をのむような瞬間。RAW形式のRAFファイルは、撮影時の豊かな情報全てを閉じ込めています。しかし、スマートフォンやウェブでの共有、あるいはビジネスシーンでの迅速なやり取りを考えると、その扱いに少々手間を感じることもあるかもしれません。特に高解像度のRAFはファイルサイズが大きくなりがちです。そこで、高画質を保ちつつ、ファイルサイズを劇的に圧縮できるHEIC形式への変換が非常に有効となります。このページでは、大切なRAF画像を、HEIC形式の利便性と効率性を兼ね備えたファイルへとスムーズに変換する方法をご紹介します。あなたの美しい写真が、より多くの場所で輝くためのお手伝いができれば幸いです。
- 漫画・アニメのデジタルアーカイブ
- ビジネス会議での資料共有
- 縦書きレイアウトへの高精細画像挿入
日本では、特にスマートフォンの普及に伴いHEICの利用が増えていますが、ビジネス用途では未だJPEGが主流の場合も多いです。しかし、高精細な画像や多数の画像を扱う際には、HEICの効率性が大きな利点となります。
About RAF (FUJIFILM) to HEIC Conversion
RAF or HEIC — 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. HEIC (High Efficiency Image Container) is Apple's format for iPhone photos, offering twice the compression of JPEG. It has limited platform support.
Full Name: RAF uses Fujifilm RAW, while HEIC uses High Efficiency Image Container. Compression: RAF uses Lossless, while HEIC uses Lossy. Transparency: RAF uses No, while HEIC uses No.
So when should you convert RAF to HEIC? This conversion is ideal when you Your RAF file is too large for email attachments or upload limits, or when you You want to reduce storage usage without noticeably affecting quality. This conversion helps you reduce file size without visible quality loss.
HEIC lossy compression can produce blurring and occasional color shifts at high compression. At the high quality settings CocoConvert uses by default, these are usually invisible to the eye. Lower quality settings trade visual fidelity for smaller file sizes.

What Happens When You Convert RAF (FUJIFILM) to HEIC
Your RAF image is decoded into raw pixel data, then re-encoded as HEIC. Some quality is permanently lost during compression. CocoConvert uses high-quality defaults to minimize this.
Your RAF file is decoded — the compressed/stored pixel data is expanded into raw RGB pixels
Pixels are re-encoded using High Efficiency Image Container's lossy compression algorithm
Metadata (EXIF, ICC profiles) is transferred where HEIC supports it
The HEIC file is saved and ready for download

Frequently Asked Questions
Should I use RAF or HEIC?
It depends on your goal. RAF preserves full quality. HEIC offers smaller files via lossy compression. Choose based on whether file size or quality matters more for your use case.
Is HEIC higher quality than RAF?
Not necessarily. HEIC lossy compression can produce blurring and occasional color shifts at high compression. At the high quality settings CocoConvert uses by default, these are usually invisible to the eye. Lower quality settings trade visual fidelity for smaller file sizes. Quality depends on the compression type and settings, not just the format name.
Can I convert RAF to HEIC 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 HEIC?
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 HEIC?
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.
