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?

High-fidelity ARW to HDR conversion for photographers and studios, designed for efficient color-rich exports and quick previews.

RAW-to-HDR Color Fidelity

Extract native sensor data from ARW and map extended luminance to HDR-friendly ranges for richer highlights and shadows.

Fast Preview Exports

Generate HDR raster outputs quickly in-browser for review, enabling iterative toning without desktop RAW imports.

Studio-Friendly Outputs

Produce widely compatible HDR files usable in grading suites and HDR-capable displays for post workflow integration.

Client-Side Processing

Files are decoded and processed locally in memory buffers, minimizing upload exposure for sensitive footage.

Efficient Batch Conversion

Process multiple ARW frames in groups to maintain throughput while conserving browser memory and CPU cores.

Save to Multiple HDR Containers

Export choices include common HDR raster containers; select container based on downstream editor compatibility.

Tips and Best Practices

Optimize your conversion workflow with technical recommendations.

Prepare ARW Originals

Shoot ARW in lossless or uncompressed mode to maximize sensor detail before HDR export
Use base ISO or pull exposures rather than pushing to reduce noise in deep shadows
Keep original ARW sidecar XMP files intact so you can reapply edits pre-conversion
Avoid in-camera heavy JPEG processing; convert from raw ARW to retain linear sensor data
Calibrate white balance in RAW before mapping to HDR to prevent hue shifts on wide-gamut displays

Choose HDR Container Wisely

Select OpenEXR for highest precision when downstream grading requires multilayer passes
Use 16-bit TIFF when compatibility with print or Photoshop is prioritized over file size
Prefer HDR containers that support embedded ICC if you need color profile handoff
Compress outputs with lossless ZIP-only where archive size matters but precision must remain
Name files to include camera model and exposure to preserve provenance during batch exports

Verify in Target Applications

Open HDR outputs in your grading suite to confirm transfer function flags and HDR primaries
Compare histogram and highlight roll-off versus original ARW in a linear viewer
Check for banding at smooth gradients; increase bit depth if quantization appears
Confirm that embedded EXIF focal-length and shutter tags match originals for cataloging
Test exports on an HDR-capable display to validate luminance and color mapping

Performance and Privacy Workflow

Process ARW batches of 20–50 files to balance throughput and browser memory usage
Keep ARW originals on local storage and run client-side conversion to limit data exposure
Close heavy background apps to free CPU cycles for demosaic and tone mapping
If conversion stalls on very large ARW files, downscale temporarily and reprocess at full size offline
Download outputs immediately and archive originals; avoid prolonged local caching in the browser

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.
