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, precise CR2 to DDS conversion tuned for game and engine workflows with clear quality vs size tradeoffs

Fast Desktop-grade Decoding

High-speed CR2 raw decoding with optimized browser CPU threads for quick DDS outputs

Control Quality vs Size

Adjust compression parameters to balance CR2 detail preservation against DDS texture size

Batch Texture Export

Convert multiple CR2 photos to DDS series with consistent settings and naming

Game Engine Ready

Produce DDS formats suitable for DirectX pipelines, including common block-compressed variants

Alpha & Mip Options

Configure alpha channel handling and generate mipmaps for DDS textures when appropriate

Client-side Processing

Files are transformed in-browser so source CR2 files do not need to be uploaded to external servers

Tips and Best Practices

Optimize your conversion workflow with technical recommendations.

Prepare CR2 for Textures

Perform white balance and lens corrections in RAW to avoid baked artifacts in DDS
Demosaic at the intended output resolution to reduce resizing artifacts during DDS compression
Export linear vs sRGB depending on whether the DDS target is for lighting or display workflows
Strip or export EXIF separately because DDS cannot reliably carry MakerNotes or camera tags
Convert color space with a verified profile before DDS encoding to prevent engine color shifts

Choose DDS Encoding Wisely

Select BC7 for high-fidelity RGB when preserving CR2 detail matters over file size
Use BC5 for normal maps derived from CR2-processed normals to keep two-channel precision
Pick DXT1/BC1 for opaque textures where smallest size is critical, but expect quality loss
Choose uncompressed or R16G16B16A16 if downstream editing requires high-bit reconstruction
Enable or disable mipmap generation depending on runtime filtering and memory budgets

Verify in Target Tools

Open DDS in your engine editor to confirm channel ordering matches CR2-derived raster
Inspect alpha or mask channels at 100% to check for quantization from compression
Compare histograms between CR2 preview and final DDS to detect color shifts
Test mipmaps on representative LODs to ensure no visible banding or aliasing
Reimport DDS into image editors supporting DDS to confirm expected bit-depth preservation

Workflow Stability

Process large CR2 batches in groups of 20–50 to avoid browser memory pressure and crashes
Export DDS to a temporary directory and run automated engine import checks before deployment
Keep original CR2 files archived for any reprocessing that requires different demosaic parameters
When using alpha masks, export mask PNGs alongside DDS to guarantee source fidelity
Close heavy GPU or memory apps while converting to maximize consistent conversion times

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.
