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?

Precision-focused conversion from Hasselblad 3FR RAW to portable PNM for editing and archival workflows

Fast RAW Rasterization

Convert 3FR sensor data into PNM raster quickly, optimized for single-image throughput in browser.

High-Fidelity Output

Maintain tonal range and avoid unnecessary downsampling when translating Bayer/CFAs to PNM bitmaps.

Universal Target Format

PNM is simple, editor-agnostic and ideal for systems needing uncompressed, easy-to-parse raster files.

Client-Side Processing

All decoding and conversion happen in-browser memory, reducing external data transfer risk.

Batch Ready

Queue multiple 3FR files for sequential conversion; good for controlled studio export runs.

Adjustable Export

Choose bit depth and color interpretation before exporting PNM to suit downstream tools or printers.

Tips and Best Practices

Optimize your conversion workflow with technical recommendations.

Prepare 3FR RAW

Use camera-saved exposure and white balance tags from 3FR to guide demosaic settings
Apply lens correction in the RAW stage if you rely on vendor distortion profiles before export
Verify ISO and gain tags so noise reduction choices during conversion are appropriate
Keep original 3FR files to preserve maker notes and proprietary tags for future edits
For bracketed sets, maintain file order to reconstruct exposure sequences after PNM export

Choose PNM Encoding

Select 16-bit PPM to retain more tonal steps when exporting high dynamic range 3FR data
Use 8-bit PPM for smaller file sizes when post-processing will include compression later
Prefer PGM for single-channel grayscale conversions derived from 3FR luminance
Package large PNM outputs into ZIP archives to reduce transfer friction
If downstream tools require ICC, keep a separate ICC sidecar with the PNM file

Color & Metadata Workflow

Map 3FR sensor linear data into a working color space before writing PNM to ensure predictable prints
Export an ICC profile sidecar referenced to the PNM when accurate color rendering is critical
Record EXIF/IPTC to a .xmp sidecar because PNM rarely carries embedded metadata consistently
Inspect white balance shifts after demosaic and adjust prior to final PNM export
Compare histogram before and after conversion to detect clipped highlights or crushed shadows

Stability & Throughput

Process batches of 20–50 3FR files to balance CPU throughput and browser memory constraints
Close other high-memory tabs when converting large 3FR files to avoid browser swapping
Convert high-resolution 3FRs on desktop devices for consistent performance and memory headroom
Run a quick checksum on exported PNMs when automating ingest to detect corruption
Keep a copy of original 3FRs until downstream editors verify color and detail fidelity

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.
