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 PGM conversion tailored for professional RAW workflows and grayscale raster pipelines.

Fast RAW Decoding

Optimized RAW demosaicing engine extracts linear pixels quickly from Hasselblad 3FR files for prompt conversion.

Pixel-Accurate Output

Exports PGM with preserved linear luminance values where possible to maintain tonal fidelity for mono processing.

Batch Ready

Process hundreds of 3FR files in one job with consistent demosaic settings and predictable PGM names.

Editor Friendly

Generated PGM files are raw-compatible grayscale bitmaps accepted by image analysis, printing, and vision tools.

Client-Side Processing

Conversions run in-browser memory buffers to reduce upload exposure; files remain on the user device during processing.

Configurable Parameters

Adjust white balance, demosaic algorithm, and bit-depth mapping before writing PGM for tailored grayscale output.

Tips and Best Practices

Optimize your conversion workflow with technical recommendations.

Prepare 3FR Inputs

Verify camera model ID inside 3FR to select correct CFA pattern for demosaic
Normalize exposure in 3FR if shots vary to avoid inconsistent PGM luminance
Strip or export embedded JPEG previews when they confuse automatic decoding
Export sidecar XMP from raw editor to retain editing parameters externally
Test a representative 3FR from each production batch before full conversion

Design PGM Output

Choose 16-bit PGM when preserving sensor linearity for scientific analysis
Map 3FR white balance into a luminance curve to match downstream viewers
Use lossless packing if your workflow supports larger PGM sizes for fidelity
Include a PGM comment with exposure key fields if EXIF cannot be embedded
Convert to 8-bit PGM only after verifying no critical shadow detail is lost

Integrate with Editors

Open PGM in image editors that accept raw-derived linear files for grading
Use TIFF as an intermediary if Adobe or Capture One requires tagged formats
Supply a matching ICC transform during import to maintain perceived tones
Document pipeline steps (demosaic, tone, quantize) for reproducible results
Keep original 3FRs alongside PGMs for reprocessing with alternate parameters

Operational Reliability

Process batches of 20–50 3FRs to balance memory use and throughput effectively
Validate PGM bit depth rendering on target analysis software before delivery
Avoid network interruptions during large zip downloads of PGM archives
Keep browser and GPU drivers updated for consistent WebAssembly decoding
Retain checksum logs for each converted PGM to detect silent corruption

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.
