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 3FR Inputs

Convert RAW white balance in 3FR before export to avoid color shifts in HDR
Demosaic 3FR in-camera or in RAW editor to compare demosaic variants before batch HDR conversion
Remove or normalize hot pixels and sensor noise in 3FR to reduce amplification in HDR shadows
Check 3FR exposure and apply highlight recovery to preserve sensor headroom during HDR tone mapping
Export a small 3FR sample to validate colorimetric response prior to large batch processing

Choose HDR Export Settings

Select HDR container that supports required bit depth to retain converted 3FR dynamic range
Use lossless or high-quality compression when target requires later editing of HDR outputs
Embed ICC profile if target viewer or CMS respects color management for accurate web rendering
Prefer 16-bit-capable formats when preserving 3FR sensor detail for post-processing
Test both perceptual and relative colorimetric mappings to find web-appropriate tone mapping

Verify Visual Results

Compare histogram between 3FR source and HDR export to check dynamic range retention
Inspect highlights at 100% to ensure no banding introduced by tone mapping
Check shadow noise amplification from 3FR during aggressive HDR expansion
Preview HDR outputs in target web viewers to confirm appearance on typical client displays
Validate key EXIF fields after conversion if downstream systems rely on capture metadata

Workflow Reliability

Process 3FR batches in groups of 20-50 to balance memory and throughput in browser
Keep original 3FR archives untouched so you can reprocess with different HDR parameters
Close other heavy applications to prevent browser memory pressure during large conversions
Use consistent preset parameters for site-wide visual consistency across converted HDR assets
Immediately verify a few exported files before uploading large HDR sets to your CMS

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.
