Quality Note

WEBP’s compression excels with photographic content from DNG files.

Frequently Asked Questions

Yes, particularly for the web. WEBP at quality 85 is usually 25–35% smaller than a comparable JPG, which matters when publishing galleries of Pixel or iPhone ProRAW captures. Every current browser has supported it since 2020.

Support varies by platform, so check before committing. X, Facebook and Pinterest accept WEBP uploads, while some scheduling tools and email clients still expect JPG. WEBP is ideal for your own site; keep JPG for platforms you do not control.

Substantially. A 20 MB Apple ProRAW DNG typically becomes a 1–2 MB WEBP at quality 85. Most of that reduction is the RAW file surrendering its unprocessed sensor latitude once the image is rendered to 8-bit, not compression alone.

Lossy for photographs. Lossless WEBP on photographic detail produces files several times larger with no visible benefit — it is designed for screenshots, diagrams and images with text.
