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, browser-based conversion from Hasselblad 3FR raw captures to VIFF for specialized scientific or archival workflows.

Raw-to-VIFF Efficiency

Directly decode 3FR frames then encode VIFF quickly for archival or analysis pipelines in one browser session.

High-Fidelity Rendering

Preserves linear sensor data where possible and avoids additional lossy chroma subsampling during VIFF export.

Client-Side Processing

Conversions run in-browser memory buffers so source 3FR files need not be uploaded to a server.

Scientific & Archival Target

VIFF output suits scientific tools and legacy viewers that expect simple raster frames and predictable pixel layout.

Adjustable Parameters

Choose output bit depth and basic color transforms; tailor VIFF payload size and numeric range before export.

Batch Conversion Friendly

Process tens to low hundreds of 3FR files per session; grouping helps memory and maintains throughput.

Tips and Best Practices

Optimize your conversion workflow with technical recommendations.

Prepare 3FR Source

Verify 3FR firmware-specific maker notes before batch decoding to avoid missing tags
Extract embedded JPEG previews from 3FR for quick visual checks without full demosaic
Ensure camera white-balance metadata is present if you want camera WB applied during conversion
Check CFA pattern and sensor orientation in 3FR to prevent mis-mosaicing after decode
Archive original 3FR files separately to retain proprietary raw data and maker notes

Optimize VIFF Output

Select the highest VIFF bit depth supported by your analysis tools to minimize quantization
Choose uncompressed VIFF only when storage allows; enable light compression for archives
Apply ICC-to-XYZ conversion before writing VIFF if downstream viewers do not read embedded profiles
Crop or rescale 3FR source prior to export to reduce VIFF file bloat for web publishing
If alpha is needed, generate and include an explicit alpha plane during VIFF export

Validate in Target Tools

Load a sample VIFF into your scientific viewer to confirm byte order and channel ordering
Compare histograms between 3FR raw render and VIFF export to detect clipping or gamut shifts
Test reading EXIF and GPS fields in the downstream application to ensure metadata usability
Verify demosaic settings by inspecting fine detail and moiré artifacts at 100% zoom
Confirm that color transforms applied during conversion match your target rendering intent

Workflow Stability

Process batches in groups of 20–50 3FR files to balance throughput and browser memory
Close heavy browser extensions and tabs to reduce memory pressure during large exports
Keep a checksum list of source 3FR files to validate round-trip integrity after conversion
Store VIFF outputs on fast local drives for analysis workflows that read multiple files concurrently
If conversion fails for a file, save the raw sample and report model/firmware to support

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.
