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-accurate conversion from Canon RAW (CRW) to portable bitmap (PBM) for photographic and design workflows

Direct RAW Decoding

Decode CRW sensor data quickly to produce a raster PBM bitmap suitable for monochrome proofs and processing.

Preserve Luminance Detail

Maintain tonal and luminance detail during conversion to a 1-bit PBM derivative for accurate black-and-white previews.

Efficient Batch Processing

Process multiple CRW files in one session with consistent dithering and threshold settings for uniform PBM outputs.

Cross-Platform Outputs

Generate PBM files readable by image tools, printers, and printing pipelines that accept Netpbm formats.

Tunable Thresholds

Adjust binary threshold and dithering to control how CRW grayscale values map to PBM black or white pixels.

Client-Side Conversion Option

Convert in-browser when available so CRW data need not leave the device, reducing transfer of raw sensor files.

Tips and Best Practices

Optimize your conversion workflow with technical recommendations.

Prepare CRW for Binarization

Apply exposure compensation to CRW highlights so detail is retained when mapped to grayscale
Set white balance on the decoded CRW to avoid luminance shifts before thresholding
Convert CRW demosaic to 16-bit grayscale first to preserve tonal gradients before downsampling
Crop CRW to final composition to avoid wasting PBM resolution on nonessential areas
Use camera shadow recovery on CRW to prevent noise turning into black pixels in PBM

Configure PBM Encoding

Select binary PBM (P4) for compact storage when compatible with target tools
Choose ordered or error-diffusion dithering for CRW images with fine texture to preserve detail
Match output DPI in PBM to your engraving or print device; PBM stores raw pixels without DPI tags
Export a ZIP package if you need to include the original CRW alongside the PBM for archival
Prefer square pixel resampling when scaling CRW to avoid aspect distortion in PBM bitmaps

Validate Output Across Tools

Open PBM in ImageMagick or Netpbm to confirm black/white mapping matches preview
Compare a rendered PBM against CRW's 100% zoom to check edge preservation
Test PBM on the target RIP or printer to ensure halftone translation is acceptable
Verify that any sidecar metadata exported from CRW is correctly associated with the PBM file
Inspect for banding introduced by aggressive thresholding and adjust dithering accordingly

Workflow Reliability & Privacy

Process sensitive CRW files client-side when available to avoid sending raw sensor data over networks
Group files into batches of 20–50 CRW images to optimize memory and avoid browser timeouts
Keep original CRW archives until PBM outputs are validated for print or engraving
Use checksums or timestamps on CRW originals and PBM outputs to track conversion integrity
Download and store PBM results promptly; the converter does not embed provenance inside PBM

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.
