Frequently Asked Questions
Is WebP supported everywhere?
Yes for modern browsers and most CMS platforms in 2026. Keep JPG when you need maximum legacy compatibility (print labs, some email clients).
Does WebP support transparency?
Yes. PNG sources with alpha are preserved when the browser encodes WebP with transparency.
What quality should I use?
75–85% is ideal for websites. Use 90%+ for hero photography where sharpness matters most.
