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, reliable conversion from Canon CRW raw captures to uncompressed PPM for editing and archival workflows

Direct Raw Decoding

Decode CRW camera RAW sensor data quickly to full-resolution raster suitable for editing in PPM.

Lossless Target Format

PPM stores RGB pixels uncompressed, preserving decoded detail and avoiding further lossy artefacts.

Wide Editor Support

Produce PPM files that open in image editors, scientific tools, and print workflows without proprietary RAW engines.

Client-Side Processing

Conversion runs locally in-browser memory buffers, keeping CRW source files on your device for privacy.

Efficient Batch Workflow

Process multiple CRW frames in sets to create PPM sequences for timelapse or film dailies workflows.

Practical Export Controls

Choose color space and output bit-depth approximations before decoding to ensure downstream compatibility.

Tips and Best Practices

Optimize your conversion workflow with technical recommendations.

Prepare CRW Originals

Check Canon model and CRW variant before decode to select the correct demosaic parameters
Verify exposure bias and shadow clipping flags in CRW metadata to choose appropriate highlight recovery
Extract or export embedded JPEG previews if you need the camera-processed look preserved
Keep sidecar copies of MakerNotes and EXIF because PPM output will not carry proprietary tags
Calibrate white balance from CRW tags and lock it if you require consistent color across a batch

Configure PPM Output

Choose 16-bit PPM when requiring higher channel precision from CRW sensor reads
Select sRGB or AdobeRGB transform during decode to produce predictable RGB values for print
Avoid 8-bit output when large dynamic range is needed; 8-bit may quantize shadow detail
Name PPM files with sequence indices for timelapse workflows derived from CRW bursts
Compress final PPMs into ZIP archives for transfer to editors that expect uncompressed rasters

Integration and Verification

Open converted PPMs in your target editor to verify color transform and bit-depth interpretation
Compare histogram and shadow detail between CRW raw render and PPM to confirm expected tonal mapping
Include an exported ICC profile or README with PPM batches to document applied color space
Automate checksum generation for large CRW-to-PPM batches to validate integrity after transfer
If using scientific analysis, record the demosaic algorithm and parameters used during conversion

Performance and Privacy

Process CRW batches in groups of 20–50 to balance memory usage and throughput in the browser
Keep CRW originals on local storage; conversion occurs in memory to minimize disk writes
Close heavy background apps when converting 24–48 MP CRW files to reduce swapping
Export metadata sidecars immediately after conversion to prevent loss of MakerNotes context
Download or archive converted PPMs promptly and clear temporary buffers to maintain privacy

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.
