Hasselblad FFF to JPG

FFF, Hasselblad's Flexible File Format, is a raw image format used by Hasselblad medium format cameras and software. It contains raw sensor data, which is excellent for editing but large and unreadable by most standard photo viewers, browsers and social platforms. Converting a Hasselblad FFF to JPG lets you share medium format work with clients, add images to a portfolio or review a shoot on any device without raw processing software.

The tool does not interpret the raw color data. It uses the JPEG preview stored inside the FFF file, which was already rendered with the camera's or software's color, white balance and contrast. Your browser decodes that preview and the tool saves it as a new JPG without an embedded color profile, which viewers and websites treat as standard sRGB. For full control over color, develop the FFF in your raw editor and export from there.

Compared with the raw data, yes. The JPG comes from the embedded preview, an 8-bit image with the rendering already applied, so the extra highlight and shadow range of the raw file is not included, and its size depends on the preview that was stored. For viewing, proofing and web use, that is usually all you need. The quality slider, from 10 to 100 percent with 90 as the default, controls the JPG compression. Do heavy retouching on the original FFF.

It depends on what your client intends to do with the files. If clients are reviewing a gallery, selecting favorite poses or posting images on social media, JPG is ideal thanks to its small size and universal compatibility. If you are delivering final, retouched images to a commercial client or a publication that needs maximum resolution and no compression artifacts for large prints, TIFF exported from your finished edit is the better choice. For everyday proofing and sharing, JPG remains the most practical format.

Medium format raw files are large, and the tool reads each FFF file in full in your browser to find the embedded preview, decode it and encode a new JPG. Larger files therefore take a little longer, and very large batches use more of your computer's memory. Nothing is uploaded, so your internet speed makes no difference; the time depends on your device and the file sizes. If your browser slows down, convert in smaller groups.

It is most useful during the initial culling and proofing stages. After a shoot, you may have hundreds of large FFF files that are difficult for clients to view. Converting a batch of them to JPG gives you a lightweight proofing gallery that clients can review to make their selections. Once they have chosen their favorites, return to the original FFF files in your raw editor, apply your final color grading and retouching, and export the final deliverables.

No. The new JPG contains the image only. Camera settings such as model, lens, focal length, aperture, shutter speed and ISO are not copied from the FFF file, though the tool does read the orientation so portrait frames come out upright. If you need shooting data with your exports, keep the original FFF files alongside the JPGs, or export from raw software that writes metadata. For client proofs and web sharing, a JPG without metadata is often an advantage.

The converter runs in the browser, so it works on phones and tablets as well as computers, as long as your browser lets you select the FFF file and the device has enough memory for a large medium format file. All the work happens on the device itself, so a phone takes longer than a laptop with big files. On location, transfer the file with a card reader, convert it and share the JPG straight away.

The JPG shows the preview exactly as the camera or software rendered it, and the tool applies no automatic correction. If it looks dark, the frame was most likely underexposed, or the preview was rendered with settings that differ from your final edit. Adjust the exposure of the FFF in your raw editor and export again, or lift the exposure and shadows of the JPG in any editing app. A very dark preview is also a useful warning to check exposure on set.

FFF is Hasselblad's own raw format, designed around its cameras, sensors and color processing. DNG, or Digital Negative, is an openly documented raw format that many cameras and programs can read and write. Both hold raw sensor data and need a raw editor to develop. Some photographers convert FFF files to DNG for long-term archiving, but when you only need a viewable, shareable image right away, extracting a JPG with this tool is much faster.
