Open RAF files in your browser
RAF is Fujifilm's RAW format, and it is unusual: the embedded preview JPEG sits at a fixed spot declared in the file header, which makes it one of the fastest formats to preview when the software knows the trick.
OnlineCull knows the trick. It reads the header, grabs the full-size preview with the film-simulation look Fuji rendered in camera, and lays the shoot out as a contact sheet in your browser.

Free. No upload: files are read on your device and never sent anywhere.
How it works
- 01
Open the folder with your RAF 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 RAF 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 RAF 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 RAF files?
- RAF comes from Fujifilm X and GFX bodies such as the X-T4, X-T5, X-H2 and GFX 100. 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 RAF to JPG here?
- OnlineCull is a viewer and culling tool, not a converter: it shows the full-size JPEG preview embedded in each RAF file. For editing and exporting finished JPEGs, hand your picks to Lightroom or any RAW developer using the XMP export.
