ARW to JPG

Sony Alpha cameras, from the A6000 series to the A7 and A1 lines, save RAW photos as ARW. Older Cyber-shot models used SRF and SR2. Sony’s Imaging Edge software and most RAW editors read them, but clients, friends and websites usually cannot. This page develops ARW files into JPG, PNG or TIFF directly in your browser, without installing anything.

The three kinds of ARW

Sony offers uncompressed RAW, compressed RAW and, on recent bodies such as the A7 IV and A1, lossless compressed RAW in several sizes. Compressed RAW uses a lossy scheme that can show faint artifacts on extreme edits but looks fine for normal use. All variants develop here. The file size tells them apart: an uncompressed 24-megapixel ARW is about 48 MB, the compressed version around 24 MB.

Neutral development versus Sony’s look

On the camera, Sony applies a Creative Look or Creative Style to JPEGs, with its own contrast and color. The sensor data developed here is neutral: white balance as recorded, a standard color conversion and no extra contrast. Pick “Embedded camera JPEG” when you want what the camera showed; pick development when you want a flatter, more editable starting point or the full resolution.

Quick proofs for clients

Photographers often need to send a gallery of proofs right after a shoot, from a laptop without their editing setup. Drop the selected ARW files, switch on Half size and a 2000-pixel size limit, choose JPG at 85 percent and convert. A 33-megapixel A7 IV file then develops in about a second, and the proofs are small enough to upload to a sharing service quickly. Final edits can come later from the original RAW files.

White balance choices

Sony’s auto white balance is generally reliable, so “As shot” is the right default. Under mixed or colored light, such as a sodium street lamp or a stage, try “Auto”, which estimates the balance from the picture itself. For fine adjustments after converting, White Balance Fixer lets you click on something neutral to correct the cast.

Old SRF and SR2 files

Early Sony DSLRs and some Cyber-shot cameras wrote SRF and SR2 files, which few current programs still open. They are supported here, which makes this a simple way to rescue pictures from an old memory card or backup disk.

Privacy and speed

Developing runs in a background worker on your own device; the RAW files never leave it. Large files from 50 and 61-megapixel bodies need a lot of memory, so convert them a few at a time on phones and older laptops. Other brands are covered by NEF to JPG, RAF to JPG and DNG to JPG.

Checking the results

Look at a converted photo at 100 percent and compare it with the camera’s screen. Colors should be close with “As shot”; if skin looks slightly paler, that is the missing Creative Look, not an error. If a file fails to develop, which can happen with a brand-new body before decoder support arrives, switch to the embedded JPEG mode, which works for practically every ARW. Keep the RAW files: the JPGs are copies for sharing, and you can always develop again later with a full editor and better tools.
