Frequently Asked Questions

Yes. Chrome, Firefox, Edge and Safari 14 and later all display WEBP, covering above 95% of live traffic. For a gallery of 45 MP EOS R5 frames the saving is worth having on mobile connections.

Typically 25–35% smaller at matching visual quality. A Canon frame that produces a 3 MB JPG at quality 85 usually lands near 2 MB as WEBP, with no visible difference at normal viewing sizes.

Lossy. Lossless WEBP on photographic detail produces files several times larger with nothing visible to show for it. Lossless mode belongs to screenshots, diagrams and images containing text, not to EOS sensor output.

Yes by default. Camera body, lens, aperture, shutter speed, ISO and GPS coordinates carry across from the CR3. Use the strip option to remove all metadata, or strip GPS alone to publish the technical record without the location.
