ARW Won't Open? Convert to JPG Instantly
Fast, instant ARW (SONY) to JPG conversion. No signup required. Just drop your .arw file and get .jpg in seconds.
Batch Settings
HDR data will be tone-mapped
Your ARW file may contain HDR (High Dynamic Range) data. JPG 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 reduction ahead
ARW is lossless, meaning every bit of data is preserved. JPG 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. JPG has limited or no support for these metadata types. Location data (GPS), camera settings, and color profiles may be stripped during conversion.
What compression artifacts to expect
JPG lossy compression can produce blockiness and mosquito noise around sharp edges. 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.

Your ARW image is decoded into raw pixel data, then re-encoded as JPG. 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
HDR data is tone-mapped to standard dynamic range (8-bit per channel)
Pixels are re-encoded using JPEG Image's lossy compression algorithm
Metadata (EXIF, ICC profiles) is transferred where JPG supports it
The JPG file is saved and ready for download

Frequently Asked Questions
Why won't my ARW file open?
ARW files may not open if your device lacks the right codec or application. Converting to JPG — a more widely supported format — usually resolves this. JPG (JPEG) uses lossy compression, making it ideal for photographs and complex images where small file size matters more than pixel-perfect quality.
Is it safe to convert ARW to JPG online?
Yes. CocoConvert encrypts your file via TLS, processes it on isolated servers in Germany, and permanently deletes it within 24 hours. Your files are never shared or analysed.
Will I lose quality converting ARW to JPG?
Your ARW file may contain HDR (High Dynamic Range) data. JPG 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. CocoConvert uses high-quality encoder defaults to preserve as much fidelity as possible.
How large can my ARW file be?
Free users can convert files up to 250 MB each. Pro users get a 5 GB limit per file, and Business API users have custom limits.
