Open RW2 files in your browser

RW2 is Panasonic Lumix RAW. It uses TIFF structures with Panasonic-specific tags, including one that holds a complete JPEG rendition of the shot.

OnlineCull reads that tag directly in your browser, which means instant previews with EXIF for a whole folder of RW2 files, no upload and no conversion step.

Free. No upload: files are read on your device and never sent anywhere.

How it works

  1. 01

    Open the folder with your RW2 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.

  2. 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.

  3. 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 RW2 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 RW2 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 RW2 files?
RW2 comes from Lumix bodies such as the G9, GH6, S5 and the LX and TZ compacts. 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 RW2 to JPG here?
OnlineCull is a viewer and culling tool, not a converter: it shows the full-size JPEG preview embedded in each RW2 file. For editing and exporting finished JPEGs, hand your picks to Lightroom or any RAW developer using the XMP export.
