Enable the plugin and it converts your images the first time a page is visited. Your originals stay on the server untouched.

What it does for your site

✅ Lighter pages with no manual work: JPG, JPEG, PNG and GIF images are converted automatically as pages are visited.
✅ Every browser gets an image it can show: supporting browsers get AVIF, then WebP, then the original as a fallback.
✅ A whole site done in one go: Bulk Generate Images converts entire folders from the Image Management tab.
✅ Your originals are safe: converted copies live in a separate folder, and Delete Converted Images removes only those copies.
✅ You stay in control: exclusion settings skip the images or pages you choose.
✅ Nothing else breaks: PDF, JSON and feed output is skipped automatically, so PDF generators keep working.
✅ Works behind a CDN: purge the CDN cache after the first conversions and you're set.

FAQ

• Does it affect PDF generators like Phoca PDF, or JSON and feed output? No. Non-HTML output is skipped automatically, so you don't need to exclude PDF URLs.
• Do I have to click Generate Images? No. Visiting pages converts images over time. Generate converts a folder in one go.
• Will my original images be deleted? No. Only the WebP/AVIF copies are ever removed.
• My host doesn't support AVIF. Can I still use it? Yes. Choose WebP only. AVIF depends on your host's image library.
