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, controlled BMP-to-HDR conversions that focus on preserving dynamic range and color fidelity for high-end imaging workflows.

Bulk BMP Handling

Efficiently ingest many uncompressed BMP files without local pre-compression or rewrapping delays.

HDR Tone Expansion

Map 8-bit BMP data into HDR containers with controlled tone mapping to improve highlight reproduction.

Consistent Batch Results

Apply identical conversion parameters across batches so brightness, white point and exposure are uniform.

Wide HDR Output Support

Produce HDR images in common formats that modern editors and renderers recognize for grading or compositing.

Adjustable Tone Mapping

Choose mappings and exposure offsets to reduce banding and preserve perceived detail in highlights.

Client-Side Processing

Files are processed in browser memory buffers; no persistent server storage is used by default.

Tips and Best Practices

Optimize your conversion workflow with technical recommendations.

Prepare BMP Source

Confirm BMP color space (often sRGB) and linearize it before HDR mapping to avoid gamma errors
Remove pre-applied compression wrappers or paletted BMP variants to ensure full RGB expansion
If BMP includes alpha, separate premultiplied alpha to avoid haloing during tone expansion
Crop and resize BMP to final pixel dimensions to minimize unnecessary HDR file growth
Export from original editor as 24/32-bit BMP to retain channels prior to float conversion

Choose Target Encoding

Select OpenEXR for multi-channel float and grading workflows requiring high precision
Use Radiance HDR (RGBE) for smaller HDR files when 32-bit float per channel is not necessary
Prefer 16-bit float for draft iterations to reduce filesize while preserving processing headroom
Avoid packed 8-bit encodings when you need accurate highlight reconstruction after tone mapping
Store auxiliary channels separately if you require nonstandard channels for compositing

Verify in Post-Tools

Open converted HDR in DaVinci Resolve or Nuke to confirm float buffer behavior and exposure
Check that the converted image reads as scene-linear if your color pipeline requires it
Inspect converted highlights for banding; apply dithering if quantization artifacts appear
Compare histograms before and after conversion to detect clipping introduced by mapping
Validate alpha channel integrity in compositing software if transparency was expected

Workflow & Storage

Batch convert in groups of 20-50 BMPs to balance memory use and throughput in-browser
Store originals separately and tag with EXIF or XMP for provenance tracking after conversion
Compress HDR archives for transfer but avoid recompressing float buffers that degrade precision
Ensure target edit suites support your chosen HDR container before large-scale conversion
Clean temporary browser storage after large exports to free system memory and disk cache

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.
