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 DNG to EXR conversion tailored for high-bit-depth imaging and batch workflows.

High-Speed Batch Processing

Optimized for large batches of DNGs to minimize per-image overhead and accelerate pipeline throughput.

Preserve Raw Detail

Converts sensor-level data in DNG to high-dynamic-range EXR channels to retain tonal range and highlight detail.

Scalable Batch Support

Process dozens to hundreds of DNGs in one job with predictable memory and time estimates for studio workloads.

Studio Format Output

EXR target files integrate with compositing and color-grading tools used in VFX and finishing pipelines.

Adjustable Conversion Options

Choose conversion parameters like bit depth and channel packing to suit downstream EXR workflows.

Client-Side Processing Model

Conversions run in isolated browser memory; local handling reduces cloud upload requirements and exposure.

Tips and Best Practices

Optimize your conversion workflow with technical recommendations.

Prepare Raw Data

Inspect DNG camera white balance and embed a chosen neutral before conversion to control EXR linear mapping
Flatten any pre-computed lens corrections in your DNG developer to avoid mismatched geometry in EXR composites
Convert DNGs with consistent demosaic settings to ensure uniform channel behavior across a batch
Export separate mask or alpha files from your raw editor if you require EXR extra channels for compositing
Standardize exposure compensation in DNG processing to prevent inconsistent highlights after EXR conversion

Choose EXR Encoding

Select 16-bit float EXR (half) for balanced disk size when archival fidelity is not full 32-bit required
Use 32-bit float EXR for VFX grading where extreme exposure rescue and compositing are necessary
Opt for PIZ compression when you need lossless-ish compression and wide-tool compatibility in render farms
Avoid heavy compression if downstream tools expect uncompressed scanline EXR for faster decode times
Name channels consistently during batch export to match compositing scripts and keep channel mapping predictable

Verify Post-Conversion

Open sample EXRs in your target compositor to confirm linearity and color primaries match your grading system
Check highlights at 1:1 to ensure no banding was introduced by float-to-float quantization choices
Confirm critical EXIF or XMP fields present in EXR attributes if downstream asset tracking depends on them
Compare pixel histograms between DNG-processed TIFF reference and EXR to detect unexpected tonal shifts
Test channel packing in EXR (e.g., R,G,B,A or multi-layer) against your automation scripts before large batches

Batch Reliability

Run batches of 20–50 DNGs to balance browser memory use and throughput for stable conversion jobs
Preflight filenames and folder structures to ensure EXR outputs map correctly into your asset system
Monitor browser memory during large batches and split jobs when encountering slowdowns or tab crashes
Keep local backups of original DNGs; conversion can expand file sizes so verify disk headroom beforehand
Automate checksum or quick visual spot checks post-batch to validate no files truncated during conversion

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.
