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.

Tips and Best Practices

Optimize your conversion workflow with technical recommendations.

Prepare JPG Sources

Avoid recompressing JPGs: use original high-quality exports to reduce quantization before HDR mapping
Convert images exported in sRGB only after confirming that embedded ICC profiles exist and are readable
If available, supply highest-resolution JPG to give tone-mapping more pixel data for highlight reconstruction
Pre-apply artifact reduction to JPG to minimize blockiness that becomes more visible after dynamic range expansion
Strip unrelated color-space tags only when you will reassign a known profile during HDR export to avoid color shifts

Target Encoding Choices

Select 12-bit or 16-bit float when preserving smooth gradations is critical for post-processing
Choose PQ/ST2084 transfer for display-targeted HDR exports to match HDR-capable monitors
Use compressed HDR containers if storage is constrained but verify playback quality on target devices
Prefer containers that support metadata if you need to later match exposure or color using EXIF
When preparing files for editing, keep both HDR and a tone-mapped SDR JPG to maintain sharing compatibility

Verification & Workflow

Open converted HDR in an HDR-capable editor to confirm tone-mapping and exposure scaling are intact
Compare histograms between JPG source and HDR output to check for unwanted clipping or boost artifacts
Preview on devices with and without HDR to ensure accessibility and provide SDR fallback images
Validate critical color targets using software that reads embedded ICC profiles to detect mismatches
Test a small batch first to confirm metadata handling before committing large archives to conversion

Sharing and Device Readiness

Provide an SDR preview (tone-mapped JPG) alongside HDR files to ensure correct appearance on non-HDR devices
Label HDR files with container and transfer function to help recipients choose compatible players
Compress HDR archives for transfer but ask recipients to unpack into HDR-aware software before viewing
For web delivery, include both an HDR asset and a fallback JPG optimized for sRGB browsers
When privacy matters, perform conversion client-side and only upload packaged HDR outputs to trusted services

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.
