What is a ARW file?
ARW (Sony Alpha RAW) is a Sony camera RAW format. Its TIFF-derived RAW container normally stores sensor data, camera metadata, and embedded previews.
ViewRawNow reads camera-written JPEG previews first. It loads local LibRaw WASM only when a suitable embedded preview is unavailable; it does not claim to develop every camera or compression variant.
How ViewRawNow opens ARW files
- Find ARW files in the selected local folder and verify the TIFF-derived RAW container.
- Inspect TIFF, EXIF, and SubIFD JPEG previews for usable embedded images.
- Choose a preview near 1800 pixels for progressively rendered cards.
- Read the largest suitable preview only when the larger viewer opens.
- Use local LibRaw WASM only when no embedded preview can be used.
- Keep RAW bytes, filenames, paths, and EXIF data on the device.

ARW viewer FAQ
Can I open ARW files online?
Yes. ViewRawNow opens ARW files from a local folder in your desktop browser. The review happens on your device rather than through a photo-upload service.
Are my ARW photos uploaded?
No. RAW data, previews, filenames, paths, and EXIF metadata remain in the browser. ViewRawNow has no RAW photo upload endpoint.
Can ViewRawNow edit or convert ARW files?
No. ViewRawNow is for previewing, sorting, inspecting, and selecting RAW photos. It does not adjust or convert sensor data.
Which Sony cameras are tested?
The current real-camera regression baseline covers Sony Alpha 7 III (ILCE-7M3) with these samples: 12-bit compressed ARW, 14-bit uncompressed ARW. Other models may work, but they are not claimed as verified.
Why can a ARW preview fail?
A usable embedded JPEG may be missing or damaged, or the file may use a variant that the bundled LibRaw cannot decode. The newest Sony compression variants may depend on an embedded JPEG or support in the bundled LibRaw version.
