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, device-ready conversion from Hasselblad 3FR raw files to OTB optimized bitmaps for sharing and editing workflows.

Fast Raw Decoding

Efficiently demosaics 3FR sensor data to produce edit-ready OTB bitmaps with minimal wait time.

High Fidelity Output

Preserves rendered tonal range and basic color accuracy when mapping 3FR linear data to OTB color buffers.

Broad Editor Support

OTB targets raster workflows used by archival and print tools that accept tiled bitmap inputs.

Local Client Processing

Conversion occurs in-browser memory, so source 3FR files are not uploaded to remote servers by default.

Flattened Layer Handling

3FR embedded layers and multi-image variations are rasterized into single-frame OTB tiles, not retained as layers.

Adjustable Decode Options

Choose output bit depth and basic demosaic parameters to balance file size and post-edit latitude.

Tips and Best Practices

Optimize your conversion workflow with technical recommendations.

Prepare 3FR Raw Inputs

Verify 3FR white balance and exposure tags to minimize post-conversion tone shifts
Keep original 3FR sidecars when present to preserve vendor adjustments for later reference
Avoid in-camera JPEG sidecar overwrites that could mislead demosaic choices during conversion
Inspect 3FR capture settings (ISO, capture curve) to select appropriate output bit depth
Group 3FR frames by resolution and sensor mode to ensure consistent OTB tile sizing

Configure OTB Encoding

Select 16-bit OTB when preserving midtone gradation from 3FR is required for print
Choose tiling size to match your target RIP or viewer to speed tiled access
Enable alpha export only for files with explicit masks to avoid unnecessary channels
Map a verified ICC profile during conversion to reduce color shifts in OTB consumers
Compress OTB archives externally (ZIP) if storage or transfer constraints exist

Verify Output in Tools

Open converted OTB in your intended editor to confirm color rendering and channel layout
Compare histogram of 3FR and OTB to detect clipping introduced during tone mapping
Check file properties for preserved EXIF fields like focal length and capture time
Validate alpha channel presence by inspecting pixel channels if masks were expected
Test a final print or soft-proof from the OTB-derived file to ensure fidelity

Workflow & Resource Tips

Batch convert 20–50 3FR files to balance browser RAM use and throughput
Close large image editors before converting to free system memory for decoding
For mobile sharing, create a low-bit PNG preview from the OTB to reduce transfer size
Keep original 3FR files archived until verification of OTB output is complete
Use local export and avoid cloud uploads when handling sensitive camera metadata

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.
