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 DNG for Rasterization

Apply camera-specific white balance or export a linearized DNG to control starting tone before conversion to BMP
If your DNG contains multiple embedded previews, select the full raw render to avoid low-resolution BMP outputs
Use lossless DNG copies when testing conversion to prevent altering original raw data during iterative exports
Strip or catalog proprietary tags separately because some DNG maker notes may not map into BMP metadata
Convert tethered shoot DNGs in short batches to spot-check demosaic results and avoid wide-scale rework

Manage BMP Output & Storage

Expect BMP files to be larger than DNG; provision storage and consider compressing BMP outputs into ZIP archives
When archival fidelity is needed, retain original DNG files alongside BMP masters to preserve camera metadata
If target editors require specific bit depth, export a proof BMP and test import before batch processing
Label BMP files with color space and render settings since embedded ICC may be inconsistent across viewers
Use external file checksums to track large BMP batches during transfer to CMS or print partners

Verify Visual Fidelity

Compare source DNG raw histograms to BMP histograms to detect clipping from downsampling to 8-bit channels
Zoom to 100% to check demosaic artifacts and edge ringing introduced during DNG to BMP conversion
Confirm white balance and shadow detail in the BMP versus your RAW editor, adjusting export tone if necessary
Inspect regions with high dynamic range from DNG to ensure highlights were mapped without banding in BMP
Test BMP imports into target CMS or desktop editors to verify color shifts and require ICC embedding if needed

Web Publishing Workflow Constraints

Avoid publishing BMP directly to web pages due to large size; convert BMP to optimized JPEG or WebP for delivery
If CMS requires bitmap uploads, consider downsampling BMP resolution to match display dimensions before upload
Use BMP as an intermediate for precise pixel edits, then export derivative web-friendly formats with proper compression
Run sample uploads to the target CDN to measure bandwidth impact of BMPs and adjust batch export settings
Purge temporary BMPs after producing final compressed assets to minimize storage and caching overhead

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.
