Open ARW files in your browser
ARW is Sony Alpha RAW. Like every RAW format it is really a TIFF container around sensor data, and like every RAW format, half the computers you sit down at cannot preview it.
OnlineCull reads the ARW header in your browser and shows the embedded preview JPEG with its EXIF: body, lens, ISO, shutter, aperture. Open a whole card, cull it, export your picks. Nothing is uploaded.

Free. No upload: files are read on your device and never sent anywhere.
How it works
- 01
Open the folder with your ARW files
Click "Open a folder" or drag the folder onto the page. OnlineCull reads the files in place; nothing is uploaded, so a full card opens in seconds.
- 02
Browse, zoom, check EXIF
Every photo appears in a contact sheet with camera, lens, ISO, shutter and aperture. Press Enter for the loupe, Z for a 1:1 focus check, and use a histogram with a clipping warning.
- 03
Rate, flag and export
Rate 1 to 5, flag picks and rejects with P and X, then export XMP sidecars that Lightroom, Bridge and Capture One read, or copy your keepers into a selects folder.
FAQ
- Is this ARW viewer really free?
- Yes. No account, no photo cap, no watermark. OnlineCull is a free in-browser tool; it makes money later through optional pro features, never by limiting viewing.
- Are my ARW files uploaded?
- No. The files are read locally by your browser and never sent to a server. That is also why it is fast: there is no upload step at all.
- Which cameras produce ARW files?
- ARW comes from Sony Alpha bodies such as the a7 III, a7 IV, a7R series, a6000 family and FX cameras. OnlineCull also reads the other major RAW formats (CR2, CR3, NEF, ARW, RAF, DNG, ORF, RW2, PEF) plus JPEG and PNG, so mixed folders are fine.
- Can I convert ARW to JPG here?
- OnlineCull is a viewer and culling tool, not a converter: it shows the full-size JPEG preview embedded in each ARW file. For editing and exporting finished JPEGs, hand your picks to Lightroom or any RAW developer using the XMP export.
