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?

Efficient, reliable 3FR to SIX conversion focused on batch productivity and predictable raster results

Fast Batch Processing

Process dozens of 3FR files quickly with optimized in-browser pipelines for steady throughput and low latency.

High-Fidelity Raster Output

SIX output prioritizes preserved tonal range from 3FR raw data when rendered to 8/16-bit raster images.

Scalable Batch Workflows

Designed for groups of 20–50 files to balance memory and speed for studio-level batch conversions.

Editor-Friendly Targets

SIX files are tailored for downstream editing tools that accept high-quality raster frames and single-image workflows.

Client-Side Processing

Conversion occurs in your browser memory buffers to minimize external transfer of original 3FR content.

Configurable Render Options

Choose output bit depth and resize settings; color profile embedding depends on source and target support.

Tips and Best Practices

Optimize your conversion workflow with technical recommendations.

Prepare 3FR Inputs

Verify each 3FR contains valid white balance tags to avoid color shifts when demosaicing
Group 3FR files by camera model so per-camera decode parameters remain consistent
Strip corrupt sidecars or incompatible edits before batch rendering to prevent decode errors
Convert RAW pairs with identical exposure stacks together to maintain tonal consistency
Confirm embedded previews versus full RAW decode to choose full demosaic for highest detail

Configure SIX Output

Select 16-bit SIX for maximum post-edit headroom when originating from high-dynamic-range 3FR
Choose sRGB SIX only for web delivery to avoid profile mismatch with common browsers
Enable alpha export in SIX when masks exist so transparency is preserved in compositing
Avoid aggressive compression in SIX if subsequent color grading is planned to reduce banding
Set output dimensions to match downstream editors to prevent resampling artifacts

Integrate with Editing Tools

Test SIX import into primary editors (Affinity, Photoshop) to confirm ICC and channel handling
Use SIX as intermediate raster when RAW toolchains cannot read specific 3FR variants
Keep original 3FR alongside SIX exports for nondestructive reprocessing if decode differs
Label batch outputs with camera and exposure metadata to speed editorial sorting
Automate post-conversion ingest into asset managers that accept SIX to maintain pipeline order

Verify & Secure Outputs

Spot-check EXIF fields in SIX to ensure critical capture data survived mapping
Validate color neutrality using gray-card shots from your 3FR batch after conversion
Run histogram comparisons between 3FR renders and SIX outputs to detect clipping
Process large batches in chunks to reduce browser memory spikes and avoid incomplete files
Store converted SIX files to encrypted volumes when handling sensitive capture metadata

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.
