What’s the Big Deal About WebP Anyway?
Before diving into the how-to, let’s quickly cover why you should care about WebP:

Advanced Tips for PNG to WebP Conversion
Want to get even more from your PNG to WebP conversion? Here are some pro tips:
Tip #1: Organize Before Uploading
Group your PNG files by type before converting:
- Keep similar image types together (e.g., product photos, icons, backgrounds)
- Convert logos and graphics with transparency separately from photos
- Consider creating a naming system that works for your website structure
Tip #2: Verify Browser Compatibility
While all modern browsers support WebP, some older browsers might not. SuperWebP doesn’t add fallbacks automatically, so consider:
- Adding .png fallbacks for critical images
- Using the <picture> element for proper fallbacks
- Testing your site in multiple browsers after implementation
Tip #3: Check Your CMS Compatibility
If you’re using WordPress, Shopify, or another CMS:
- Verify WebP is supported in your theme
- Consider plugins that help manage WebP implementation
- Check that your media library correctly displays WebP
Tip #4: Optimize Images Before Converting
For absolutely optimal results:
- Resize images to their display dimensions before uploading
- Remove unnecessary metadata from original PNGs
- Then convert to WebP with SuperWebP
This multi-step approach ensures the smallest possible file sizes.
