Sony ARW to JPG: a practical guide for Alpha, ZV and RX shooters

ARW is Sony's RAW format, written by every Alpha, ZV and RX camera that shoots RAW. Here is what is inside those files, which settings matter, and how to get a good JPG out of them without installing anything.

If you shoot a Sony camera in RAW, you end up with a folder of .ARW files. They hold far more information than the camera's own JPEGs, but phones, messaging apps and most websites cannot display them. This page explains what makes Sony's format a little different from other brands, which in-camera options change the files you get, and how to develop them into JPGs that look right.

Where ARW comes from

Sony introduced ARW ("Alpha RAW") with its first Alpha DSLR in 2006, and the same extension has carried through the SLT cameras, the full-frame and APS-C mirrorless lines, the ZV vlogging bodies and the RX compacts. The extension never changed, but the contents did: Sony has revised the internal structure several times as sensors, bit depths and compression options evolved. That is why a very new camera can produce an ARW that older software refuses to open even though the file name looks identical to one from 2014.

Compressed, uncompressed or lossless: which ARW are you shooting?

For years Sony offered only one kind of RAW: a compressed ARW that uses a lossy scheme to roughly halve the file size. In most photos you will never see the difference. The exception is high-contrast edges in otherwise smooth areas, such as a dark branch against a bright sky or star trails at night. Pushed hard in editing, compressed ARW files can show faint halos or posterized fringes along those edges.

Sony later added an uncompressed option to many bodies, in some cases through firmware updates. It avoids those artifacts but roughly doubles the file size. More recent cameras, beginning with bodies released from about 2021, add lossless compressed, which keeps every bit of data while still saving space. If your camera has it, lossless compressed is the sensible default for most people.

• Lossless compressed: best balance. Use it if available.
• Uncompressed: use it on older bodies when you shoot high-contrast scenes, astrophotography, or plan heavy edits.
• Compressed (lossy): fine for everyday travel, family and event photos, and the best choice when card space or burst depth matters.

Whatever you choose, the file still opens as an ARW. RAWSnap decodes all three variants the same way, so this is purely a quality versus storage decision you make in the camera menu.

What your camera settings do (and don't do) to an ARW

A common surprise is that the JPG you export from a RAW converter does not look like the image on the camera's screen. The reason is that many settings only affect the camera's own JPEG processing. They are stored as notes in the file, but the sensor data itself is untouched:

• Creative Style / Creative Look (Standard, Vivid, FL, IN and so on) is not baked into the RAW. Third-party converters, including RAWSnap, start from a neutral rendering.
• DRO (Dynamic Range Optimizer) lifts shadows in the JPEG. The RAW is not lifted, so shadows will look darker until you raise the Shadows slider yourself.
• Picture Profiles such as S-Log apply to video, not to RAW stills.
• White balance is the exception that carries over: the as-shot setting is stored in the file and RAWSnap uses it as its starting point.

If you want the camera's exact look, Sony's free Imaging Edge Desktop is the converter most likely to reproduce Creative Looks faithfully. For everything else, a neutral start plus a few slider moves is usually quicker. Our guide on why RAW files look flat goes deeper into this.

Sony color: what to adjust first

Sony's color rendering has improved a lot over the generations, but a few tendencies show up often enough that they are worth checking on every batch:

1. Skin can look slightly green or cool. Try Temp +5 to +10 and Tint +3 to +8 (toward magenta). Small numbers are enough; if faces start looking pink, back off the Tint first.
2. Highlights hold more than you think. Modern Sony sensors keep a lot of detail in bright areas. Pull Highlights down to around -30 or -40 before raising Exposure so bright skies keep their tone. Areas that already develop as pure white can't be brought back by a browser converter like RAWSnap; a full RAW editor can reach further into the file's highlight headroom.
3. Shadows are clean at base ISO. On a well-exposed ISO 100 frame you can push Shadows to +40 or more without much noise. At ISO 6400 and above, keep shadow lifts modest, because RAWSnap has no noise reduction slider.
4. Mixed indoor light. Auto white balance under tungsten often stays warm on purpose. If you want a neutral result, lower Temp until whites look white, then add a little Vibrance back.

For more on these moves, see white balance in RAW and recovering highlights and shadows.

Converting ARW to JPG in the browser

1. Open RAWSnap and choose one or several .ARW files. They are decoded on your device and never uploaded.
2. Start from Natural, or tap a preset such as Portrait or Golden Hour, then fine-tune Temp, Highlights and Shadows.
3. Save. "Save for phone" gives a 2048-pixel JPEG for sharing; "Save full quality" keeps every pixel. With several files open you can download them all as a ZIP.

When an ARW won't open

Most failures fall into a few predictable groups:

• A camera released in the last few months. Every new body needs decoder support. Open-source decoders like LibRaw, which RAWSnap uses, typically add new models some time after launch. In the meantime, Imaging Edge Desktop will open them, or Adobe's free DNG Converter can turn them into DNG files once Adobe supports the model.
• Pixel Shift composites (.ARQ). Pixel Shift Multi Shooting saves a set of normal ARW frames, which Imaging Edge combines into an .ARQ file. RAWSnap does not open ARQ, but you can open any single frame from the set.
• A damaged file. If the camera was switched off during writing or a card was removed too early, the ARW can be truncated. Try opening it in another program; if nothing reads it, the data is usually gone.
• Very old browsers or low-memory phones. Large uncompressed files need a lot of memory to decode. A desktop browser handles a7R files more comfortably than an older phone.

When another tool is the better choice

RAWSnap is designed for quick, private conversions with a preset and a few sliders. It is not a full editor. Use something else if you need to:

• apply Sony lens corrections for distortion and vignetting (Lightroom, Capture One, darktable or Imaging Edge do this);
• remove noise from high-ISO RX or APS-C files;
• make local adjustments with masks or brushes;
• export 16-bit TIFFs for print retouching.

Capture One has long offered a Sony-focused edition, and Imaging Edge is free. If you are deciding between editors, our RAW editor comparison lays out the trade-offs.

FAQ

Can I convert ARW to JPG without Lightroom?

Yes. Sony's free Imaging Edge Desktop can export JPGs, and browser tools like RAWSnap develop ARW files locally without an install or an upload.

Why does my converted ARW look darker or flatter than on the camera screen?

The camera screen shows a JPEG preview with your Creative Look and DRO applied. Those settings are not part of the RAW data, so a neutral conversion looks flatter. Raising Shadows and adding a little Contrast and Vibrance usually closes the gap.

Should I shoot compressed or uncompressed ARW?

Choose lossless compressed if your camera offers it. On older bodies, uncompressed avoids rare edge artifacts in high-contrast scenes, while compressed is fine for most everyday photography and saves a lot of space.

Why can't I open my Pixel Shift .ARQ file?

An ARQ is a composite that Sony's Imaging Edge builds from several ARW frames. RAWSnap reads the individual ARW frames, not the combined ARQ, so open one frame for a normal-resolution JPG or use Imaging Edge for the composite.
