How to Convert ARW to JP2 — Quick & Free
Fast, instant ARW (SONY) to JPEG 2000 conversion. No signup required. Just drop your .arw file and get .jp2 in seconds.
Batch Settings
HDR data will be tone-mapped
Your ARW 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 ARW file may contain MakerNote, XMP metadata. JP2 has limited or no support for these metadata types. Location data (GPS), camera settings, and color profiles may be stripped during conversion.
About ARW (SONY) to JPEG 2000 Conversion
Short answer: yes, you can convert ARW to JP2 online for free, and some quality differences may occur depending on the format types. Just upload your .arw file to CocoConvert, pick JP2 as the output, and click Convert. The whole process takes seconds.
Now for the details. ARW is Sony's RAW photo format preserving the full dynamic range captured by the sensor. JP2 (JPEG 2000) offers wavelet-based compression with better quality than JPEG at the same bit rate. Converting between these two formats lets you convert between formats quickly.
Full Name: ARW uses Sony Alpha RAW, while JP2 uses JPEG 2000. Compression: ARW uses Lossless, while JP2 uses Lossy & Lossless. Transparency: ARW uses No, while JP2 uses Yes.
Your ARW file is decoded and re-encoded as JP2. Your ARW 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.
CocoConvert runs entirely online — no software to install, no account to create. Your files are encrypted during upload (TLS), processed on isolated servers in Germany, and permanently deleted after 24 hours. It works in Chrome, Safari, Firefox, Edge, and all mobile browsers.
Need to convert more than one file? Free users can do 5 per hour. Pro gets 100 per hour with files up to 5 GB each.

What Happens When You Convert ARW (SONY) to JPEG 2000
Your ARW image is decoded into raw pixel data, then re-encoded as JP2.
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 2000's lossless compression
Metadata (EXIF, ICC profiles) is transferred where JP2 supports it
The JP2 file is saved and ready for download

When NOT to Convert
- ✗You want to preserve HDR information — JP2 only supports standard dynamic range
Frequently Asked Questions
Is ARW to JP2 conversion free?
Yes. CocoConvert offers free ARW to JP2 conversion with generous daily limits — 25 minutes of processing time and up to 5 files per hour (250 MB each). Pro plans remove these limits.
How fast is ARW to JP2 conversion?
Most files convert in 2–10 seconds depending on size. Large image files may take 30 seconds. Batch jobs process in parallel for maximum speed.
What happens to my files after conversion?
Your uploaded ARW file and the converted JP2 file are both automatically deleted from our servers within 24 hours. They are never shared, sold, or analysed.
Does converting ARW to JP2 lose quality?
Your ARW 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.
Can I convert JP2 back to ARW?
Yes, CocoConvert supports JP2 to ARW conversion as well. However, if the original conversion involved lossy compression, converting back won't recover the lost data.
Versions are pinned in our worker Dockerfile and re-built via CI on every change.
