When to Convert

Common scenarios where this conversion is useful

Sharing Adobe/universal photos without RAW software

Not everyone has Lightroom or Capture One. Converting your DNG files to AVIF lets anyone view and use your photos with standard image viewers and web browsers.

Photography portfolio websites

Convert DNG photos to AVIF for your portfolio site. Smaller file sizes mean faster page loads, which improves both user experience and SEO rankings.

Online gallery optimization

Photo galleries with dozens of high-resolution images benefit dramatically from AVIF compression. Visitors see your photos faster, especially on mobile connections.

Blog and content marketing

Photography blogs and tutorials need high-quality images that load quickly. AVIF delivers both, keeping readers engaged without bandwidth penalties.

Frequently Asked Questions

Does converting DNG to AVIF 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 AVIF 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 DNG 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 DNG 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 DNG files. High-resolution cameras may produce larger RAW files — the authenticated API supports up to 500MB.

Is AVIF better than WebP for DNG photos?

AVIF produces files roughly 20-30% smaller than WebP at the same quality, and 50% smaller than JPG. For photo content, AVIF excels at preserving fine detail and smooth gradients. The tradeoff is slower encoding and slightly less browser support than WebP.

Why does AVIF conversion take longer?

AVIF uses AV1-based encoding which is computationally intensive. The extra processing time (10-20 seconds vs 5-10 for JPG) produces significantly smaller files with superior quality. This is a one-time cost that benefits every viewer of the image.

Which browsers support AVIF?

Chrome 85+, Firefox 93+, Safari 16.4+, and Edge support AVIF. This covers the vast majority of web users. For older browsers, serve a JPG or WebP fallback using the HTML <picture> element.
