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?

Convert Canon CRW raw photos to PNG for archiving, editing, and web compatibility with a fast browser-based tool.

Fast Local Conversion

Convert CRW files to PNG directly in your browser without uploads, minimizing round trips and latency.

Preserve Raw Detail

Render CRW sensor data into high-resolution PNG outputs that retain full raster detail and visible dynamic range.

Wide Compatibility

PNG outputs open in editors, CMS platforms, and browsers reliably for archiving or publishing workflows.

Client-Side Processing

Processing occurs in-browser memory buffers to limit data exposure; nothing is uploaded unless you choose.

Adjustable Render Options

Set output dimensions and basic color options to control PNG pixel size and apparent sharpness.

Archival-Friendly Output

PNG produces lossless raster files suitable for archival preservation and editing pipelines.

Tips and Best Practices

Optimize your conversion workflow with technical recommendations.

Prepare CRW for Conversion

Shoot RAW with a neutral picture style to reduce in-camera tonal curves baked into CRW renders
Embed a custom white balance in the CRW only if you want that WB baked into the PNG pixels
Use lossless compressed CRW variants to reduce transfer time without altering sensor detail
Avoid in-camera HDR stacks stored as proprietary compound CRW; those will be flattened into a single PNG
Rename CRW files to a consistent schema so batch processing preserves intended ordering and metadata mapping

Configure PNG Output

Select 16-bit PNG when preserving tonal gradients matters; expect larger files than 8-bit outputs
If archival fidelity is priority, keep both original CRW and exported PNG copies for reprocessing
Enable PNG compression level only to reduce size; compression is lossless and does not alter pixels
Avoid automatic downscaling if you plan to crop or retouch later; export at native resolution
When embedding ICC, verify the written profile in an inspector to ensure color-managed workflows remain intact

Verify Post-Conversion

Open the PNG in a color-managed viewer to confirm white balance and highlight rolloff match expectations
Inspect EXIF or tEXt chunks after export to check which CRW metadata tags survived the conversion
Compare histograms of CRW render and PNG to detect unwanted clipping from tone mapping
Zoom to 100% to evaluate demosaic artifacts or aliasing introduced during RAW decoding
Test PNG in target browsers and CMS to confirm upload limits and rendering gamma

Workflow and Privacy

Process sensitive CRW files locally in the browser to avoid cloud transfers that could expose content
Split large shoot batches into groups of 20–50 CRW files to avoid memory spikes during decoding
Close other heavy applications to free CPU and RAM for smoother demosaic and PNG encoding
Download converted PNGs promptly and securely archive or encrypt if storing sensitive imagery
Keep originals until post-production and archiving workflows are validated across your toolchain

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.
