Quality reduction ahead
ARW 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 ARW 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
ARW 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.

考虑到大陆用户对微信生态的依赖，HEIC格式在iOS设备上原生支持良好，但安卓设备和PC端可能需要第三方应用或查看器。因此，转换为HEIC后若需在多平台流通，建议同时考虑其兼容性。
About ARW (SONY) to HEIC Conversion
ARW or HEIC — which format should you use? The answer depends on your needs. Here's a quick breakdown.
ARW is Sony's RAW photo format preserving the full dynamic range captured by the sensor. 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: ARW uses Sony Alpha RAW, while HEIC uses High Efficiency Image Container. Compression: ARW uses Lossless, while HEIC uses Lossy. Transparency: ARW uses No, while HEIC uses No.

What Happens When You Convert ARW (SONY) to HEIC
Your ARW 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 ARW 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 ARW or HEIC?
It depends on your goal. ARW 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 ARW?
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 ARW 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 ARW 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 ARW 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.
