When to Convert

Common scenarios where this conversion is useful

Sharing Canon photos without RAW software

Not everyone has Lightroom or Capture One. Converting your Canon RAW (CRW) files to PNG lets anyone view and use your photos with standard image viewers.

Quick delivery of client proofs

Photographers can quickly convert Canon RAW (CRW) selects to PNG for client review. Fast delivery with professional quality, without the full RAW editing workflow.

Social media and web publishing

Convert Canon RAW (CRW) photos to PNG for immediate publishing. Get your shots online without importing into editing software.

File size reduction for sharing

Canon RAW (CRW) files are 10-80 MB. Converting to PNG dramatically reduces file size, making them practical for email attachments and messaging apps.

Frequently Asked Questions

Does converting Canon RAW (CRW) to PNG lose quality?

RAW files contain 12-bit of color data per channel. Converting to PNG applies professional dcraw processing. Lossless output preserves all processed image data.

What about white balance and exposure?

dcraw automatically applies the camera's recorded white balance settings from your Canon RAW (CRW) file. For creative control over exposure and color temperature, use dedicated RAW software like Lightroom first.

Can I batch convert multiple Canon RAW (CRW) files?

The web interface handles one file at a time. For batch processing, use the authenticated API (/v1/convert) which supports automated workflows.

Is the conversion secure?

Your Canon RAW (CRW) file is uploaded via encrypted TLS, processed using dcraw, and automatically deleted immediately after conversion. We never store or analyze your photos.

What is the maximum file size?

The web converter accepts files up to 25MB (eligible paid browser access: 100MB). Most RAW files from consumer cameras fit within this limit. High-megapixel cameras may produce larger files suited to the API.

What software normally opens Canon RAW (CRW) files?

Canon RAW (CRW) files from older Canon DSLR and PowerShot cameras require specialized software: Canon Digital Photo Professional, Adobe Lightroom, Capture One, or RawTherapee. ChangeThisFile uses dcraw for server-side processing without requiring any software installation.

Why use Canon RAW (CRW) instead of in-camera JPEG?

Canon RAW (CRW) captures full sensor data with 12-bit per channel, preserving maximum detail and dynamic range. Unlike in-camera JPEG, RAW files let you adjust white balance, exposure, and color in post-processing without quality loss.

Will EXIF metadata be preserved?

The conversion focuses on pixel data. EXIF metadata (camera settings, GPS, date) from the original Canon RAW (CRW) file is not carried to the output. Keep the original RAW file if metadata preservation is needed.

How long does Canon RAW (CRW) to PNG conversion take?

RAW processing with dcraw typically takes 5-20 seconds depending on file size and server load. Large 12-bit RAW files require more processing time than standard images.
