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 CR2 files to PNG lets anyone view and use your photos with standard image viewers and web browsers.

Preparing photos for further editing

Convert CR2 to PNG as a lossless intermediate format before editing in Photoshop, GIMP, or other tools. PNG prevents quality loss from repeated saves during your editing workflow.

Product photography with future transparency needs

E-commerce photographers can convert CR2 product shots to PNG, then remove backgrounds for clean product images on white or transparent backgrounds.

Technical and scientific imaging

When pixel accuracy matters (microscopy, astronomy, forensic photography), PNG preserves exact pixel values from your CR2 conversion without compression artifacts.

Who Uses This Conversion

Frequently Asked Questions

Does converting CR2 to PNG lose quality?

Some quality reduction is inherent when converting from RAW to any standard format. RAW files contain 12-14 bits of color data per channel, while PNG uses 8 bits. However, dcraw applies professional white balance and color processing to produce high-quality output. The result looks excellent for sharing, printing, and web use.

What about white balance and exposure adjustments?

dcraw automatically applies the camera's recorded white balance settings. Unlike Lightroom or Capture One, you can't manually adjust exposure or color temperature before conversion. If you need creative control over RAW processing, use dedicated RAW software first.

Can I batch convert multiple CR2 files?

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

Is the conversion secure?

Your CR2 file is uploaded via encrypted TLS, processed on our servers using dcraw, and automatically deleted immediately after conversion. We never store, view, or analyze your photos.

What's the maximum file size?

The web converter accepts files up to 25MB (free tier; 500MB on Pro), which covers most CR2 files. High-resolution cameras may produce larger RAW files — the authenticated API supports up to 500MB.

Why choose PNG over JPG for CR2 conversion?

PNG uses lossless compression, preserving every pixel from the RAW processing. Choose PNG when you plan to edit the image further (no re-compression degradation), need transparency support, or when the image contains text/sharp edges. Choose JPG when file size matters.

How large will the PNG be?

PNG files from RAW conversions are typically 10-30MB depending on image resolution and content complexity. That's larger than JPG (2-8MB) but smaller than uncompressed formats. The lossless quality makes it worth the extra size for editing workflows.

Can I edit the PNG and maintain quality?

Yes. PNG's lossless compression means you can open, edit, and re-save the file repeatedly without any quality degradation. This makes it ideal as an intermediate format in editing workflows.
