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, camera-native CRW to OTB conversion focused on preserve visual fidelity and manageable output sizes

Optimized Camera RAW Handling

Decode Canon CRW raws quickly using native demosaic pipelines for accurate base rendering before export to OTB.

Quality-Focused Output

Produce OTB files tuned to minimize artifacts while balancing compression and tonal fidelity for print or archive.

Wide Editing Compatibility

OTB target files are suitable for editors that accept tiled, multi-resolution image stores for non-destructive workflows.

Local Client-Side Processing

Conversions run in the browser memory buffers to reduce cloud transfer exposure and keep source CRW files local.

Configurable Export Parameters

Adjust compression level and color conversion settings to favor smaller files or maximum tonal detail in OTB.

Efficient Batch Workflow

Queue dozens of CRW images for sequential processing with steady per-image performance and ZIP packaging for download.

Tips and Best Practices

Optimize your conversion workflow with technical recommendations.

Prepare CRW Source Details

Verify CRW exposure and white balance adjustments because these are baked into the demosaiced OTB output
Export or note camera serial and LensInfo if MakerNotes are required externally since MakerNotes may not be preserved
Use native camera profiles or RAW development presets before converting to avoid double color transforms
Crop and remove hot pixels in the RAW stage so OTB tiles store only finalized pixel data
If you need linear sensor data, export a DNG alternative first because OTB will contain rendered pixel data after demosaic

Choose OTB Encoding Strategy

Select lower compression for archival OTB to retain subtle tonal gradations from CRW demosaic
Enable tile pyramid output for large CRW images to reduce viewport load in tiled viewers
Include ICC embedding when available to keep color intent between CRW camera matrices and OTB consumer apps
Avoid maximum compression if you plan heavy local edits; artifacts become more visible during retouching
Use 16-bit export option only when post-processing requires greater headroom, but confirm viewer support

Verify Visual Fidelity Post-Conversion

Open OTB in your target editor and compare histograms to the CRW-derived preview to spot clipping
Check shadow detail and highlight roll-off because tone-mapping during conversion can alter perceived exposure
Inspect seams at tile boundaries at full zoom to ensure compression artifacts are not introduced
Compare color channels against the camera preview to detect mismatched color matrix mapping
Confirm embedded EXIF exposure tags match rendered pixel values for audit and catalog workflows

Workflow Safety and Performance

Process CRW batches in groups of 20-50 to balance browser heap usage and maintain responsiveness
Keep original CRW files in secure archives until you validate OTB visual and metadata fidelity
Disable unnecessary browser extensions to free memory when converting high-megapixel CRW files
If privacy is critical, remember processing occurs in-browser; do not upload files to unknown networked services
Schedule large conversions on desktops with more RAM and faster SSDs to reduce swap-induced artifacts

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.
