3FR

3FR is the camera RAW format of Hasselblad medium-format cameras. It stores unprocessed sensor data with high bit depth, so photographers can adjust exposure, white balance, and color after the shot. Most everyday apps cannot open 3FR files directly, so they are often converted to JPG, PNG, or TIFF for sharing and editing.

JPG

JPG is the most common file extension for JPEG images and the standard format for photos. It uses lossy compression that makes files small while keeping good visual quality, and every device, browser, and app can open it. JPG does not support transparency, and each new lossy save can reduce quality slightly.

What happens when 3FR becomes JPG

Source format

3FR is the image source or target format for this conversion path.

Target format

JPG uses lossy compression and does not support transparency.

What changes

The 3FR pixels are decoded and written using JPG compression and color capabilities.

What is preserved
Pixel dimensions and visible composition are preserved unless resize or crop settings are selected.
What may be lost
Layers, editable vectors, camera-raw controls, animation, high bit depth, and metadata are preserved only when JPG supports them.
Codec and quality implications
JPG uses lossy compression. A higher quality or bitrate can reduce new artifacts, but it cannot restore detail already missing from the 3FR source.
Realistic limitations
Multi-page, layered, animated, camera-raw, or very large images may be flattened, reduced to one frame, or rejected if the decoder cannot safely read them.

Conversion steps

  1. Upload a 3FR file no larger than 1 GB.
  2. Confirm that JPG is selected as the target.
  3. Download the JPG file and check the result before deleting your source.

Troubleshooting

The 3FR file is rejected or will not open.
Confirm that the file is not empty, password-protected, or corrupt and that its real format matches the extension.
The JPG file is larger than expected.
Choose a more efficient codec or lower quality setting when available. Lossless and uncompressed targets are often larger by design.
Transparency, color, or animation changed.
Choose a target that supports the needed feature and keep the original file; JPG cannot store transparency or animation.

Privacy and file retention

Uploads and converted files are processed automatically and irreversibly deleted within 24 hours. You can delete them sooner with the delete control. Convertr does not read, mine, sell, or manually review file contents.
