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.

Tips and Best Practices

Optimize your conversion workflow with technical recommendations.

Prepare CRW for Decoding

Validate CRW white balance to avoid baked-in color casts after linear float export
Apply black-level subtraction when CRW contains sensor offsets to ensure correct shadows
Remove in-camera noise reduction to retain raw detail for PFM float processing
Convert proprietary Canon sensor matrices to a working RGB prior to exporting float PFM
Group CRW files by exposure settings so batch demosaic parameters remain consistent

Manage PFM Storage & Export

Expect PFM to expand CRW compressed data into much larger float files; plan disk allocation
Use ZIP packaging for batches of PFM to reduce transfer sizes while keeping floats intact
Export 16-bit float variant only when downstream tools require reduced precision to save space
Keep CRW originals archived to reprocess if color matrix handling needs adjustment
Record conversion parameters in a sidecar to reproduce float decode settings later

Verify Color and Detail

Compare CRW raw histogram to PFM output to confirm highlight retention after float decode
Inspect edges and demosaic artifacts at 100% to ensure no interpolation errors were introduced
Check color rendering in a color-managed editor when CRW contains custom ICC data
Confirm absence of alpha channels since CRW does not supply true transparency
Test PFM exports in your post pipeline before committing to a full batch conversion

Workflow & Privacy Considerations

Process CRW to PFM locally in the browser to avoid third-party exposure of raw capture data
Use batches of 20–50 CRW files to balance memory and maintain steady conversion throughput
Close memory-heavy applications when decoding large CRW files to prevent browser memory pressure
Keep sidecar metadata backed up to avoid accidental loss when PFM lacks embedded EXIF
Download and verify ZIP archives immediately after conversion to reduce retention on device

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.
