Why Serve WebP Instead of JPG?
JPG has served the web faithfully since 1992 — but compression science moved on. WebP applies three decades of improvements (spatial prediction, better entropy coding, smarter color handling) to deliver the same visual quality at 25–35% smaller sizes. Multiply that across every photo on a page and the difference is felt: faster loads, better Core Web Vitals, lower bandwidth bills, happier mobile users.
The Quality Sweet Spot
Quality percentages aren't comparable across formats — WebP at 80% looks like JPG at 90%. Our recommended default (80%) is what most CDNs and image services use for their automatic WebP variants. Go to 90% for portfolio/photography sites, 55–70% for thumbnails and dense galleries.
Deployment Cheat Sheet
- WordPress: upload WebP directly (supported since 5.8) — or convert your media library and re-insert.
- Static sites: swap file references, or use the
<picture>fallback pattern for legacy browsers. - Marketplaces & socials: check acceptance first — some upload forms still demand JPG; keep originals for those.
Complete the Pipeline
Convert your PNG graphics too with PNG to WebP. Received WebPs you can't open elsewhere? WebP to PNG reverses course. And when a platform insists on JPG under a size cap, the JPG compressor with target-size mode is your friend.
