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, photographer-focused CRW to RAS conversion with control over raster output and reliable local processing.

Fast CRW Decoding

Efficient CRW raw decode pipeline minimizes wait time for high-resolution Canon RAW photo conversion.

High-Fidelity Raster Output

Produce RAS bitmaps that preserve rendered tonal range and per-pixel luminance after demosaicing.

Client-Side Processing

Files are decoded and written in-browser memory, keeping source CRW files on the user device for privacy.

Editor-Friendly Results

RAS outputs are simple uncompressed raster bitmaps that import cleanly into editors and printing pipelines.

Adjustable Render Options

Choose basic rendering such as output resolution and color profile conversion before writing RAS files.

Predictable File Sizes

RAS typically expands CRW compressed data into larger bitmaps; our estimates help plan storage needs.

Tips and Best Practices

Optimize your conversion workflow with technical recommendations.

Prepare CRW for Rasterization

Inspect CRW white balance and set a neutral WB to avoid baked-in color shifts during demosaicing
Apply lens correction flags in decode settings so RAS output aligns with corrected geometry
If CRW contains multiple exposures, export each file separately to avoid unintended frame merges
Use the highest native resolution when planning large prints to retain detail after CRW demosaic
Convert CRW to a linear or chosen working profile before export to preserve highlight rolloff

Control RAS Output Size

Select 8-bit or 16-bit RAS depending on gradation needs; 16-bit increases file size significantly
Downscale CRW resolution prior to conversion to reduce RAS disk footprint for web previews
Package RAS outputs in ZIP archives for batch transfers and storage efficiency
Avoid saving unnecessary multiple RAS copies; keep one master 16-bit render per CRW source
Monitor resulting RAS file size in a test export to set batch storage requirements

Verify Post-Conversion Fidelity

Open RAS in your target editor to confirm color and contrast match the CRW render intent
Compare shadow and highlight detail at 100% to detect clipping introduced during render
Check that any applied ICC conversion appears consistent across proofing devices
Validate that embedded metadata fields required by your workflow are present in sample RAS files
Confirm alpha channel presence if you supplied a mask; ensure mask alignment before batch run

Workflow Stability & Privacy

Process CRW batches in groups of 20-50 to avoid excessive browser memory pressure
Close other memory-intensive applications to keep in-browser decoding stable during conversion
Keep original CRW files archived as a raw master in case RAS renders require re-export
Use local, offline tools for final soft-proofing when handling sensitive client images
Download converted RAS immediately and clear any temporary session data after completion

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.
