Need help?3FR to HEIC Converter
3FR is Hasselblad's proprietary RAW format, written by the company's medium-format H-system and X-system cameras to store unprocessed sensor data. HEIC is Apple's HEVC-based still-image format — compact and 10-bit capable, but supported natively almost only inside Apple's ecosystem. Converting renders the RAW into a finished, shareable picture: you trade the editing latitude of the original 3FR for a file that is a fraction of the size.
3FR Format at a Glance
| Property | Value |
|---|---|
| Owner | Hasselblad (proprietary) |
| Introduced | 2006, with the Hasselblad H2D — successor to the earlier Imacon 3F |
| Container | Based on TIFF; conforms to the EXIF metadata standard |
| Payload | Unprocessed RAW sensor data (typically 12- or 14-bit per channel) |
| Compression | Lossless on older bodies; uncompressed on many newer ones |
| Typical resolution | Medium-format, roughly 39 MP (H2D) up to 100+ MP on current backs |
| Reference processor | Hasselblad Phocus (its own RAW software) |
| Best for | Archiving the original capture and editing exposure/white balance later |
HEIC Format at a Glance
| Property | Value |
|---|---|
| Standard | HEIF (ISO/IEC 23008-12) carrying HEVC/H.265-encoded images |
| Adopted by Apple | 2017, with iOS 11 and macOS High Sierra |
| Color depth | Up to 10-bit, with HDR support |
| Typical file size | About half the size of an equal-quality JPEG |
| Native support | iOS/macOS; Android 10+; Windows needs the paid HEVC extensions |
| Browser support | Among browsers, only Safari opens HEIC natively |
| Best for | Saving storage inside an Apple-centric workflow at high quality |
How to Convert 3FR to HEIC
- Upload Your 3FR File: Drag and drop your
.3frfile, or click "+ Add Files" to select it. You can queue several captures and convert them with the same settings. - Pick a Quality Preset: Leave the Quality Preset on "Very High (Recommended)" to keep detail, or switch to "Specific file size" to target a fixed output size — useful when the source 3FR is hundreds of megabytes.
- Set the Resolution (Optional): Use Resolution Percentage or Preset Resolutions to downscale a 50-megapixel-plus capture, or set Width/Height with "Keep aspect ratio" for an exact dimension.
- Convert and Download: Click "Convert" to render the RAW and download the HEIC. No sign-up, no watermark.
Frequently Asked Questions
Will I lose editing latitude by converting 3FR to HEIC?
Yes. A 3FR holds unprocessed sensor data, so white balance and exposure are non-destructive metadata you can change freely in Phocus or Lightroom. Rendering to HEIC bakes those decisions in and demosaics the file, so large later corrections — pulling up a badly under-exposed shot, for example — won't recover as cleanly as they would from the RAW. Convert when you've finished editing, and keep the original 3FR for the archive.
Why is the HEIC so much smaller than the 3FR?
Two reasons. The 3FR stores full-resolution sensor data, often 39 megapixels to 100-plus on Hasselblad medium-format backs, sometimes uncompressed. HEIC uses HEVC (H.265) compression, which Apple states is roughly half the size of an equal-quality JPEG. So a multi-hundred-megabyte 3FR can become a HEIC of a few megabytes while still looking good on screen.
Can every device open the HEIC file I get?
No — that is HEIC's main limitation. It is native on iOS 11+/macOS High Sierra and on Android 10 and later. Windows can open it only after installing Microsoft's paid HEVC Video Extensions, and among web browsers only Safari renders HEIC. If you need a picture that opens anywhere, convert the 3FR to a more universal format instead with our 3FR to JPG converter or 3FR to PNG converter.
Does the HEIC keep the 10-bit color of the Hasselblad capture?
HEIC can carry up to 10-bit color and HDR, so it preserves more tonal range than an 8-bit JPEG. It is still a lossy, rendered file rather than RAW, so it will not match the full 12- or 14-bit latitude of the original 3FR. For grading work, edit the 3FR first and export HEIC as the delivery file.
How does this compare to Hasselblad's own Phocus software?
Phocus is Hasselblad's reference RAW processor and uses the company's color profiles, so for maximum color fidelity and full control over the raw rendering it is the better tool. This converter is for when you just need a finished HEIC quickly without installing software — for example, sharing a proof. In our testing, a 39-megapixel 3FR at the "Very High" preset produced a HEIC of roughly 3 to 6 MB, a small fraction of the source file.
Does converting preserve the EXIF metadata?
The 3FR is based on TIFF and conforms to the EXIF standard, so it carries camera, lens, and exposure metadata. The converter renders the image data to HEIC; EXIF such as capture settings is generally retained, though Hasselblad-specific maker-note fields and the editable RAW adjustments do not carry across to a finished still.
Are my uploaded files kept private?
Files are uploaded over an encrypted connection, processed on our servers, and deleted automatically a few hours after conversion — no sign-up, no watermark, never shared or made public. If you want a smaller HEIC after converting, you can run the result through our HEIC compressor.
