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, browser-based DNG to DDS conversions tuned for game and 3D texture workflows with clear quality vs size choices

Lossless / Fast Conversion

Convert DNG raw frames to DDS rapidly in-browser with multi-threaded decoding for common camera packs.

Tunable Quality

Choose compression presets for DDS (BCn) to balance visual fidelity and GPU-ready file size.

Game & Engine Ready

Output DDS variants suitable for DirectX/OpenGL pipelines and common engines like Unity and Unreal.

Client-side Processing

Files are processed in your browser memory; no server uploads required for conversion tasks.

Color Handling

We decode DNG imagery and map color to standard RGB; verify ICC embedding as results may vary.

Advanced Encoding Options

Select target DDS format (BC1-BC7, uncompressed) and choose whether to include mipmaps where applicable.

Tips and Best Practices

Optimize your conversion workflow with technical recommendations.

Prepare Raw DNG Sources

Apply camera-specific white balance in raw editor to lock color before converting to DDS
Denoise or apply sensor-level corrections to DNG to avoid compressing noise into BCn blocks
Export an intermediate TIFF if you need baked-in ICC profiles before DDS encoding
Flatten any HDR merges in source DNG stacks to a single radiometric image for predictable DDS output
Confirm exposure and highlight handling so compression won’t exaggerate clipped regions

Choose DDS Encoding Strategically

Select BC1 for opaque textures to minimize filesize when alpha is unnecessary
Use BC3 or BC7 for alpha-containing assets to retain transparency fidelity from derived masks
Prefer BC7 for game UI or high-detail RGB where block artifacts are unacceptable
When precision matters, export uncompressed RGBA32 DDS despite larger file sizes
Generate mipmaps in the converter to keep runtime sampling consistent across LODs

Validate Engine Compatibility

Test a converted DDS sample in your target engine to confirm import re-encoding behavior
Match DDS format selection to the GPU family expected in deployment to avoid runtime fallbacks
Verify that the engine honors DDS embedded mipmaps versus auto-generating its own
Check that alpha semantics (straight vs premultiplied) align between conversion output and engine import
Confirm that high-precision DDS formats are supported by target hardware before choosing them

Metadata, Privacy and Workflow

Export EXIF/XMP sidecars when provenance must accompany DDS because DDS may not preserve metadata
Process sensitive DNGs locally and remove temp files since compression artifacts are irreversible after export
Group conversions into 20–50 file batches to balance memory and throughput in-browser
Keep a verified master copy of original DNGs for future reprocessing with different engine targets
Label output DDS files with codec and mipmap flags to avoid ambiguity in asset pipelines

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.
