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 TIF.
Looking to convert TIF to ARW? Here's the honest answer — and what works instead.
Turn your file into a share-worthy AI Effect — one tap, no prompts.
TIFF is a high-quality, often lossless raster format used in photography, scanning and print. Files are large but preserve maximum detail.
TIFF opens in Photoshop, GIMP, Preview and professional imaging 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 TIF 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 TIF 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 TIF into ARW or any real RAW.
TIF converts cleanly to PNG, JPG, TIFF and WEBP — free, no sign-up, no watermark.
