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?

Fast, reliable 3FR to PFM conversions tailored for photographers and design workflows.

Fast Raw Decoding

Efficient debayering and decoding pipeline to quickly translate Hasselblad 3FR raw data into pixel images.

High-Fidelity Output

Produce high-precision PFM float images that retain captured tonal range and extended dynamic detail.

Editing Ready

PFM outputs open directly in HDR-aware editors and scientific tools without intermediate resampling.

Local, Private Processing

Client-side conversion reduces upload exposure; files stay on your device during transformation.

Batch Friendly

Process shoots in groups; efficient memory use keeps throughput steady for typical studio workflows.

Preserve Linear Float Data

Convert to PFM float maps that represent linearized scene data suitable for HDR compositing.

Tips and Best Practices

Optimize your conversion workflow with technical recommendations.

Prepare Raw Decoding

Verify camera white balance in 3FR before decoding to keep consistent linear color matrices
Export lens corrections from 3FR metadata to apply prior to PFM export to avoid geometric artifacts
If applying demosaic options, choose a conservative algorithm to preserve micro-detail from 3FR sensors
Record exposure and ISO from 3FR EXIF into sidecar to maintain processing traceability
Convert tethered 3FR batches in identical pipeline settings to ensure consistent PFM float scales

Manage PFM Outputs

Expect PFM files to be larger than 3FR; budget storage when converting high-megapixel Hasselblad files
Use lossless external compression (e.g., ZIP or 7z) if archival PFM storage is required to reduce footprint
Keep original 3FR files as authoritative masters in long-term archives alongside PFMs
When exporting many PFMs, write per-image sidecars with ICC and EXIF to avoid data loss
Clear temporary conversion buffers after export to free disk and memory resources

Color & Metadata Workflow

Detect the camera color matrix from 3FR and document the conversion target (linear sRGB or camera linear) in sidecars
If you rely on ICC profiles, load sidecar profile into your editor before importing PFM for consistent rendering
Check shadow roll-off and highlight clipping at 100% to ensure linearization from 3FR was accurate
Compare histograms between 3FR-derived TIFF previews and PFM to catch decoding anomalies
If maker notes are critical for cataloging, export them into searchable metadata files during conversion

Workflow Performance Tips

Process shoot batches of 20–50 3FR files to balance CPU and RAM during PFM creation
Close intensive GPU-accelerated apps while decoding large 3FR files to reduce contention
Validate a small sample PFM before committing to full-run conversions for consistent results
Use SSD storage for input and output paths to accelerate read/write of large float files
Immediately archive or move PFMs after conversion to avoid cluttering working disk space

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.
