What file formats do you support?

We support over 100 file formats including images (JPG, PNG, GIF, WebP, TIFF), documents (PDF, DOC, DOCX, TXT), videos (MP4, AVI, MOV), audio (MP3, WAV, FLAC), and many more specialized formats.

Yes, absolutely. We use enterprise-grade encryption for all file transfers. Your files are automatically deleted from our servers after conversion, and we never store or access your personal data.

What is the maximum file size?

The maximum file size for free users is 100MB per file. Premium users can convert files up to 1GB. For larger files, we recommend our batch processing feature.

How long does conversion take?

Most files convert in under 30 seconds. The exact time depends on file size and format complexity. Our advanced algorithms ensure the fastest possible conversion while maintaining quality.

Can I convert multiple files at once?

Yes! Our batch processing feature allows you to upload and convert up to 50 files simultaneously. This is perfect for bulk conversions and saves significant time.

Do I need to create an account?

No account is required for basic conversions. However, creating a free account gives you access to batch processing, file history, and priority support.

Why Choose Our Converter?

Convert Hasselblad 3FR raw images to SUN raster for archival compatibility and broad legacy viewer support.

Preserve Raw Detail

Extracts linear RGB from 3FR sensor data to retain tonal detail for archival SUN files.

Legacy Format Support

Produces SUN-compatible raster bitmaps for older tools and institutional archives requiring .sun format.

Efficient Local Conversion

Performs client-side decoding of 3FR frames quickly, minimizing upload time and preserving privacy.

Color Profile Guidance

Maps common Hasselblad camera profiles to linear or sRGB outputs; verify ICC embedding separately.

Client-Side Privacy

Conversion runs in-browser memory buffers so source 3FR files need not be uploaded to servers.

Archive-Ready Output

Creates uncompressed SUN raster images suitable for long-term storage and compatibility testing.

Tips and Best Practices

Optimize your conversion workflow with technical recommendations.

Prepare 3FR Source

Verify 3FR contains full-resolution sensor frames before converting to avoid exporting camera previews
Note embedded white balance in 3FR and lock it if you require consistent output across batches
Export or copy original 3FR sidecar XMP files to retain edits and camera-capture parameters
Check for manufacturer-specific compression flags in 3FR that might alter demosaic results
If 3FR includes multiple exposure frames, separate them into individual files to preserve source sequencing

Configure SUN Output

Select 16-bit SUN variant when preserving high dynamic range from 3FR to reduce quantization
Choose uncompressed SUN for archival masters to ensure pixel-perfect reversibility from decoded data
If ICC profiles are required, export profiles as sidecar .icc alongside the SUN file for color management
Enable alpha export only if your 3FR source contains a mask or transparency layer to avoid empty channels
Use ZIP packaging for batches to retain EXIF sidecars and ensure one-file archival transfer

Validation & QA

Open SUN outputs in a color-managed viewer and compare rendered patches against 3FR-derived references
Inspect histograms to detect highlight clipping introduced during linear-to-sRGB mapping
Verify critical EXIF fields like capture time and camera model were retained in sidecar or header
Compare pixel-level crops at 100% zoom to confirm demosaic artifacts are within acceptable limits
Test SUN files in your legacy archiving software prior to large-scale migration

Workflow Reliability

Process batches of 20–50 3FR files to balance speed and memory usage in browser environments
Keep original 3FR files unchanged and store SUN conversions as separate archival derivatives
Close other memory-heavy applications to prevent browser timeouts during large 3FR decodes
Record conversion parameters (bit depth, color space) in a manifest for long-term provenance
Download and verify exported ZIP archives immediately to avoid transient storage issues

Fast Processing

Close unused tabs for maximum throughput.

Client-Side Privacy

No media leaves your device.

Broad Compatibility

Output files work across all operating systems.

Pro Tip

For batch conversions, process in groups of 20-50 files to optimize memory usage and avoid browser slowdowns.
