How to convert ARW to JPG

An .arw file is Sony's RAW format — what a Sony Alpha camera writes when you shoot RAW instead of, or alongside, JPEG. It isn't a picture yet. It's the unprocessed readout of the sensor, holding up to 14 bits of tonal data per pixel where a JPG stores 8, plus the camera's own notes on how it would have rendered the shot. That headroom is the whole point of RAW — and the reason a single ARW file runs to tens of megabytes.

That is also why almost nothing opens it. Turning sensor data into an image is a develop step — demosaicing, white balance, a tone curve — that only software with a RAW engine can do, so email clients, upload forms, most viewers and every website either reject the file or show a blank thumbnail. Converting to JPG runs that develop once and saves the result in the one format everything accepts. The ARW format page has the fuller background.

The EditItAll ARW to JPG converter develops the RAW with a native-speed engine and writes a JPEG, and the whole job runs entirely in your browser:

1. Open the converter and drop in your .arw files — one frame or a whole card. Batches are processed together.
2. Each file is developed right on your device: decoded from raw sensor data into a full-color image using standard automatic settings.
3. Choose a JPG quality level. High keeps the detail the develop produced; lower trades fine detail for a smaller file.
4. Download. A single photo saves as a .jpg; a batch comes down as one ZIP.

Because nothing is uploaded, you can disconnect from the internet after the page loads and keep converting — worth knowing when a card holds hundreds of files at tens of megabytes each. It's free, with no account, no watermark and no limit on how many you convert — the same batch handling is covered in how to batch convert images to JPG. Prefer a lossless copy? The ARW to PNG converter runs the same develop and saves PNG instead.

Two caveats, stated plainly. First, the develop is automatic. The engine applies standard white balance, tone and color settings — there are no exposure, white-balance or highlight-recovery sliders, because this is a converter rather than a RAW darkroom. If a frame needs tonal work, convert it first, then open the JPG in the photo editor and adjust levels and curves there; the editor itself can't open RAW.

Second, JPG is lossy and it bakes the development in. The ARW keeps everything the sensor recorded — the latitude to pull a sky back or lift the shadows years from now. The JPG keeps only the finished 8-bit picture at the quality you chose. So treat the JPG as the share copy and the ARW as the negative: convert freely, keep the originals. If the JPGs still need to be smaller for email or an upload form, run them through the JPG compressor afterwards. The exported JPGs also leave EXIF and GPS metadata behind, so a shared photo doesn't reveal where it was taken.

Every camera maker has its own RAW flavor, and the same on-device develop exists for the common ones: CR2 to JPG for Canon, NEF to JPG for Nikon, and DNG to JPG for Adobe's universal container, which Leica, Ricoh, drones and the RAW modes of many phones write directly.
