Need help?3FR to WebP Converter
3FR is Hasselblad's proprietary RAW format — the unprocessed 16-bit sensor data written by H-, X-, and V-system medium-format cameras and digital backs. WebP is Google's web image format that does both lossy and lossless compression plus transparency. This converter renders the RAW into a finished WebP: the editing latitude of the original sensor file is baked down to a standard image, in exchange for a file that opens in any modern browser and is markedly smaller than the same picture saved as JPEG or PNG.
3FR Format at a Glance

WebP Format at a Glance
| Property | Value |
|---|---|
| Full name | WebP image format |
| Developer | Google (announced 2010) |

How to Convert 3FR to WebP
- Upload Your 3FR File: Drag and drop or click "+ Add Files" to load one or many 3FR files. Hasselblad medium-format RAWs are large, so the practical wait is upload time over your connection; files travel over an encrypted link and are deleted automatically a few hours after conversion.
- Set Lossless? and Quality Preset: Leave Lossless? on No (Recommended) for photographs and set the Quality Preset (default Very High) — this is the lossy WebP path that gives the smallest file at near-original quality. Switch Lossless? to Yes only when you need pixel-exact output and can accept a larger file.
- Set Image Resolution (Optional): Under Image resolution, keep the original to preserve the camera's full detail, or pick a Resolution Percentage or a preset width/height to downscale a 100-megapixel frame to web dimensions and cut the output further.
- Convert and Download: Click "Convert" and grab each WebP individually or as a ZIP. No sign-up, no watermark.
Frequently Asked Questions
Does converting 3FR to WebP lose the RAW editing latitude?
Yes — and this is the key trade-off. A 3FR holds 16-bit unprocessed sensor data, so you can recover highlights, push shadows, and set white balance after the fact with almost no penalty. WebP is an 8-bit rendered image: once it is written, the demosaicing, white balance, and tone curve are fixed. Convert to WebP for delivery and sharing, but keep the original 3FR (or a 3FR to TIFF export) as your archival master if you may want to re-edit.
Why is my WebP still a large file when WebP is "small"?
Because Hasselblad bodies are very high resolution. A 100-megapixel frame is 100 million pixels regardless of format, so even efficient WebP compression of a full-resolution medium-format image can run into several megabytes — far larger than a phone photo's WebP. If you only need web or proofing dimensions, downscale with Resolution Percentage in step 3; that does more to shrink the file than the codec alone.
Should I use lossy or lossless WebP for a rendered Hasselblad photo?
For photographs, use lossy (Lossless? set to No). Per Google, lossy WebP is 25–34% smaller than an equivalent-quality JPEG, and at the Very High preset the difference from the source render is hard to see. Reserve lossless WebP for flat graphics, screenshots, or cases needing pixel-exact reproduction — on a continuous-tone photo it produces a much bigger file for no visible gain.
Will the conversion keep my EXIF and copyright metadata?
WebP can carry EXIF, XMP, and ICC profile chunks, so capture data and copyright fields are preserved where present in the source. Some RAW-specific maker-notes and Hasselblad-only fields have no WebP equivalent and may not survive the render. If embedded copyright is critical to your workflow, confirm it on a test file before batch-converting.
Does every browser open a WebP file?
Effectively yes today — WebP support is around 96% globally. Chrome (32+), Firefox (65+), and Edge support it, and Apple added it in Safari 14 on macOS Big Sur and iOS 14, with full lossless and animated WebP from Safari 16. For an audience on much older devices, a 3FR to JPG export is the maximally compatible fallback.
How does this compare to converting 3FR straight to JPEG or PNG?
WebP is the smaller modern choice: at matched quality it beats JPEG by 25–34% and beats PNG by ~26% losslessly, and unlike JPEG it can also hold transparency. JPEG wins only on reach to legacy software; PNG wins only when you need lossless line-art or an alpha channel without WebP support. In our testing, a full-resolution Hasselblad render saved as Very High lossy WebP came out noticeably smaller than the same frame exported as maximum-quality JPEG, with no visible quality difference at normal viewing size. If you already have a WebP and just want it smaller, run it through Compress WebP.
Can I batch-convert a whole Hasselblad shoot at once?
Yes — add multiple 3FR files and they are processed with the same Lossless?, Quality, and resolution settings, then returned individually or as a single ZIP. Because medium-format RAWs are large, total time is dominated by uploading the set rather than the conversion itself.
