ARW is Sony's in-camera RAW
ARW is the raw sensor data a Sony camera writes at the moment of capture. It's produced by the camera's own hardware and firmware — software can read it, but nothing can manufacture a genuine ARW from a finished JPG.
Looking to convert JPG to ARW? Here's the honest answer — and what works instead.
Turn your file into a share-worthy AI Effect — one tap, no prompts.
JPG (JPEG) is a lossy raster format that compresses photographs into small files by discarding detail the eye barely notices — the most widely used photo format on the web and in cameras.
JPG opens in every browser, image viewer and editor with no special software.
ARW is Sony’s raw photo format, storing unprocessed sensor data from Alpha cameras for full editing latitude.
ARW opens in Lightroom, Photoshop, Capture One and Sony Imaging Edge.
No. ARW stores the raw signal a Sony sensor recorded at capture. A JPG is a finished image with that data already baked in and discarded — there's nothing for a converter to reconstruct.
RAW formats like ARW give maximum editing latitude — but only when they come straight from the camera. Converting a JPG to ARW would just wrap a finished image in a RAW container, with none of the benefits.
DNG is an open RAW container. You can convert a camera's own RAW (including ARW) into DNG, but you still can't turn a regular JPG into ARW or any real RAW.
JPG converts cleanly to PNG, JPG, TIFF and WEBP — free, no sign-up, no watermark.
