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?

Reliable, offline-capable conversion from Hasselblad 3FR raw captures to portable PPM bitmaps for archival and compatibility.

Raw-to-Bitmap Throughput

Fast client-side decoding of 3FR raw frames into uncompressed PPM bitmaps for immediate use and archiving.

Pixel-Accurate Rasterization

Converts sensor data to full-resolution PPM pixels without introducing extra lossy compression stages.

Batch Friendly

Process dozens of 3FR files in one session; batching reduces repetitive overhead and simplifies archive exports.

Wide Toolchain Compatibility

PPM is a simple portable bitmap readable by image tools, linters, and legacy render pipelines for archival access.

Client-Side Privacy

Conversion runs in the browser memory space; files are not uploaded to external servers by default.

Adjustable Decode Options

Choose demosaic method and exposure scaling before output to control highlight handling and tonal range.

Tips and Best Practices

Optimize your conversion workflow with technical recommendations.

Prepare 3FR Inputs

Inspect 3FR EXIF for shutter, ISO, and white balance before decoding to choose correct demosaic parameters
Check for embedded JPEG preview in 3FR to compare render vs raw decode and detect corrupted frames
If 3FR uses manufacturer compression, test with one file to confirm decode fidelity before batch runs
Prefer using original Hasselblad exposure and matrix tags during conversion to reduce color shift
Keep original 3FR files in an archive alongside PPM outputs for provenance and future reprocessing

Target PPM Encoding

Choose 16-bit PPM output when preserving 3FR sensor dynamic range is critical for archiving
When generating 8-bit PPM, apply controlled tone mapping to avoid highlight clipping from 3FR raw data
Use separate alpha mask PPM files if you need transparency derived from matte extraction
Bundle PPMs into compressed ZIP or TAR.GZ for long-term storage to offset uncompressed size
Label PPM files with original 3FR filenames and sidecar metadata for traceable archives

Workflow Integration

For editors that require metadata, export XMP sidecars from 3FR and pair them with the PPM bitmaps
Convert sample 3FR files to PPM and test import into your pipeline (ImageMagick, GraphicsMagick, raw processors)
If downstream tools do not accept 16-bit PPM, convert to TIFF after verification to keep metadata and bit depth
Automate naming conventions so PPMs map back to camera serial and capture timestamps extracted from 3FR
Validate color by importing PPM into your color-managed editor and comparing against reference rendering

Verify and Secure Archives

Perform checksum verification on both original 3FR and produced PPM to ensure bit-for-bit archive integrity
Retain original 3FR files offline to allow future re-decode as raw decoders improve
Limit batch sizes per session to avoid browser memory pressure that can corrupt outputs
Encrypt compressed archives containing PPM and 3FR pairs for secure offsite backups
Document decoding settings (demosaic, white balance, bit depth) in sidecar metadata for reproducibility

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.
