Quality reduction ahead
ARW is lossless, meaning every bit of data is preserved. HEIF 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 ARW file may contain MakerNote metadata. HEIF 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
ARW stores up to 14 bits per channel, but HEIF 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
HEIF lossy compression can produce blurring and occasional color shifts. 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.
大切な思い出や作品を写し取ったARWファイル。その豊かな階調や繊細な色彩は、クリエイティブな表現には欠かせないものです。しかし、ファイルサイズが大きく、共有や管理に少々手間がかかることも。そこで、次世代の画像フォーマットとして注目されているのがHEIFです。HEIFは、ARWの持つ高画質を保ちつつ、ファイルサイズを劇的に圧縮できる優れもの。まるで、重厚な巻物を、軽やかな扇子に仕立て直すかのように、あなたのデジタルライフをもっと快適に、もっと自由に彩ります。このページでは、ARWからHEIFへの変換を通じて、あなたの写真体験がどのように進化するかをご紹介いたします。
- 漫画・アニメ制作の素材共有
- ビジネスにおける高解像度資料の送付
- SNSでの高画質写真のアップロード
日本のスマートフォン市場ではHEIF対応が広く進んでおり、特にiPhoneユーザーにとっては、変換後のファイルがOS標準で扱いやすいという利点があります。縦書きの文書など、特定のレイアウトを多用する場面でも、HEIFの効率性は有効です。
About ARW (SONY) to HEIF Conversion
Whether you're one of the many photographers, designers, and content creators who work with ARW files daily, there comes a time when you need HEIF instead. ARW is Sony's RAW photo format preserving the full dynamic range captured by the sensor.
Here's a typical scenario: you receive a .arw file but your project, platform, or client requires .heif. HEIF stores images using highly efficient HEVC compression, commonly used on Apple devices. Rather than searching for desktop software or wrestling with command-line tools, you can convert ARW to HEIF online in seconds with CocoConvert.
This conversion is ideal when you Your ARW file is too large for email attachments or upload limits, or when you You want to reduce storage usage without noticeably affecting quality. The conversion helps you reduce file size without visible quality loss.
HEIF lossy compression can produce blurring and occasional color shifts. 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.
Behind the scenes, CocoConvert uses industry-standard tools — FFmpeg for audio and video, Sharp for images, qpdf for documents. Your file is uploaded securely (TLS encryption), processed on isolated servers in Germany, and auto-deleted within 24 hours. No account, no watermark, no hidden fees.
Power users can batch convert up to 100 files simultaneously with a Pro subscription, making it practical for production workflows.

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