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 CRW to EXR conversion focused on archival fidelity and cross-platform compatibility for professional workflows.

Optimized for Speed

Fast client-side decoding of CRW frames with streamlined EXR write paths to minimize roundtrip time.

High Bit-Depth Output

Convert CRW sensor data to 16-bit or 32-bit EXR to preserve tonal gradation for archival and grading.

Wide Editing Support

EXR outputs are compatible with Nuke, Blender, DaVinci Resolve and professional color tools.

Client-Side Privacy

Files are processed in browser memory so originals do not need to be uploaded to a remote server.

Batch-Ready

Efficient batch conversion with predictable per-image timing for archive preparation.

Adjustable Depth & Compression

Choose target EXR pixel types and lossless vs tiled compression for storage versus speed trade-offs.

Tips and Best Practices

Optimize your conversion workflow with technical recommendations.

Prepare CRW for Demosaic

Check CRW white balance settings before demosaic to avoid baked color shifts in EXR
Extract camera raw matrix from CRW if available to improve linear conversion fidelity
Where possible, apply lens corrections prior to export to prevent resampling artifacts in EXR
Convert CRW to linear space in EXR to simplify downstream compositing and grading
Avoid in-converter sharpening on CRW to retain full sensor detail for high-bit EXR grading

Choose EXR Encoding Strategically

Select half (16-bit float) EXR for balance between disk and dynamic range when archiving CRW derivatives
Use ZIP or PIZ compression for archival EXR to maintain lossless pixel fidelity from CRW conversions
Prefer tiled EXR when working with very large CRW scans to enable region-based editing in compositors
Enable multi-channel naming in EXR to carry additional passes exported from CRW workflows
Avoid B44A for archival masters since it prioritizes speed over maximal lossless retention

Verify Post-Conversion Attributes

Open EXR in a color-managed viewer to confirm linear transfer and highlight rolloff after CRW decode
Inspect EXR headers for embedded EXIF tags transferred from CRW and note any missing maker notes
Compare pixel histograms between CRW raw render and EXR output to detect clipping introduced by conversion
Test EXR in your target compositor to ensure tile and compression settings are supported
Confirm channel ordering (R,G,B,A) in EXR matches downstream render pipelines expected by VFX tools

Archive and Workflow Hygiene

Always retain original CRW masters alongside EXR derivatives for forensic or reprocessing needs
Label EXR files with conversion parameters (bit depth, compression) to ease future retrieval
Process batches of CRW in groups of 20-50 to limit browser memory pressure and preserve system responsiveness
Store EXR archives on redundant media and checksum files after conversion to detect bit-rot
When exporting for remote teams, include a small JPG preview and a metadata sidecar referencing the CRW source

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.
