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 conversion from Hasselblad 3FR RAW to portable PBM for archival and broad compatibility.

Fast RAW to PBM

Convert 3FR RAW frames to PBM quickly for immediate archiving or downstream processing.

Pixel-Accurate Rasterization

We rasterize 3FR sensor data into a lossless PBM bitmap to preserve visible luminance detail.

Broad Compatibility

PBM outputs open in legacy image tools, text-based pipelines, and simple viewers without plugins.

Local Client Processing

Conversions occur in the browser memory space to reduce external file transfers and exposure.

Control Export Parameters

Set output dimensions and simple preprocessing options before PBM export for tailored archives.

Archive-Friendly Outputs

PBM files are uncompressed and deterministic, simplifying integrity checks and long-term storage.

Tips and Best Practices

Optimize your conversion workflow with technical recommendations.

Prepare 3FR Source

Verify Hasselblad 3FR capture settings so demosaic outcomes match expected dynamic range
Convert proprietary camera linear data to scene-referred RGB before grayscale mapping when needed
Extract EXIF/XMP sidecars from 3FR to retain exposure and lens data for archival reference
Check for embedded multi-exposure stacks in 3FR export workflows and flatten externally if required
Crop or downscale 3FR originals prior to PBM export to control final bitmap dimensions

Target PBM Encoding

Select desired grayscale bit depth to balance archive fidelity and PBM viewer compatibility
Understand PBM stores uncompressed bitmap data, so expect larger files than 3FR for long exposures
Use ZIP compression after conversion to reduce storage footprint while keeping PBM deterministic
If needing color retention, generate a separate RGB export before converting to PBM grayscale
Embed metadata as a sidecar JSON when PBM is used as an archival bitmap for cataloging

Workflow & Software

Open PBM outputs in Netpbm-compatible viewers or convert to TIFF for advanced editors like Photoshop
When integrating into CMS, reference the original 3FR filename and include EXIF sidecar for provenance
For image analysis pipelines, prefer 16-bit PBM representations if your tools accept higher precision
Automate batch groups by camera serial or capture date to keep PBM archives traceable to sources
Test target display pipelines with representative PBM files to confirm luminance mapping matches expectations

Verification & Performance

Compare histograms between 3FR decode and PBM output to detect clipping introduced by conversion
Process large batches in segments of 20–50 3FR files to avoid browser memory saturation
Keep original 3FR files in cold storage for legal or scientific archival requirements rather than relying on PBM alone
Use checksums on PBM outputs and 3FR originals to validate integrity after transfer or storage
If color-critical, verify perceived brightness on target devices since PBM removes chroma information

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.
