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 CRW to DDS conversion tailored for game textures and web-ready assets.

Optimized for Speed

Convert Canon RAW (CRW) files into DDS quickly using in-browser processing without uploads.

Pixel-First Quality

Maintain native CRW image detail when rasterizing RAW sensor data into high-quality DDS textures.

Game & Engine Ready

Output DDS variants suitable for engines that expect S3TC/BCn compressed texture formats.

Client-Side Privacy

All decoding and encoding happens in your browser memory; files are not uploaded to our servers.

Adjustable Encodes

Choose compression profiles and mipmap generation to balance quality and runtime size for DDS.

Batch Texture Packs

Process sets of CRW photos into DDS texture sheets or individual compressed DDS files in bulk.

Tips and Best Practices

Optimize your conversion workflow with technical recommendations.

Prepare CRW for Texture Use

Demosaic and apply desired white balance to CRW before encoding to preserve intended tonality
Crop CRW to power-of-two dimensions if your target engine requires mipmapped DDS textures
Apply sharpening and noise reduction on CRW sensor data to minimize compression artifacts in DDS BCn blocks
Export multiple exposure merges from CRW externally if you need high dynamic range before DDS conversion
Convert CRW color space to the working space used by your engine to avoid unexpected shifts in DDS

Choose DDS Encoding Wisely

Use BC7 for high-fidelity RGB when CRW detail matters and engine supports it to minimize block artifacts
Select DXT1 for opaque textures from CRW to maximize size savings when alpha is not needed
Pick DXT5/BC3 when CRW-derived alpha channels are supplied or generated to keep smooth transparency
Generate mipmaps from the decoded CRW raster to prevent shimmering and improve GPU sampling of DDS
Prefer uncompressed RGBA DDS if you need lossless transfer of CRW-derived 16-bit channels for editing

Integrate with Engines and Tools

Test converted DDS in your target engine (Unity/Unreal) as CRW tonal mapping may differ after compression
Use engine import presets that expect DDS compression type you selected to avoid runtime transcoding
Automate filename conventions so CRW source metadata like exposure or ISO maps to DDS asset metadata
Check GPU memory budgets because CRW to DDS conversion can change size dramatically depending on BCn codec
Validate normal maps and linear-space conversions from CRW-derived images to avoid lighting artifacts

Verify Output and Pipeline Safety

Confirm that EXIF-critical fields were exported to sidecar files since DDS may discard camera metadata
Run visual QA on converted DDS for banding or blockiness introduced by BCn compression choices
Avoid overwriting CRW masters; keep originals for reprocessing if DDS compression needs adjusting
Monitor browser memory during large CRW batches because local decoding is memory intensive
Use checksums on DDS outputs to ensure batch integrity when integrating into web publishing 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.
