Open DNG files in your browser

DNG is the open RAW format: Leica, Ricoh and Pentax write it natively, iPhone ProRAW and DJI drones produce it, and Adobe's converter turns any other RAW into it.

OnlineCull reads the DNG structure in your browser, extracts the embedded preview and EXIF, and handles phone-style orientation correctly, so your portrait shots show up portrait.

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

How it works

  1. 01

    Open the folder with your DNG 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 DNG 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 DNG 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 DNG files?
DNG comes from iPhone ProRAW, DJI drones, Ricoh GR, Leica and Pentax, plus anything converted by Adobe DNG Converter. 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 DNG to JPG here?
OnlineCull is a viewer and culling tool, not a converter: it shows the full-size JPEG preview embedded in each DNG file. For editing and exporting finished JPEGs, hand your picks to Lightroom or any RAW developer using the XMP export.
