Why convert PNG to WebP?
Speed. PNG files are often the heaviest thing on a page, especially screenshots, hero graphics and product images exported straight from a design tool. WebP usually stores the same image in a much smaller file, so pages load faster, which helps visitors on mobile and the page speed checks that tools like Lighthouse and PageSpeed Insights run. Every current browser shows WebP, and WordPress, Shopify, Webflow and most other platforms accept it as an upload.
Does WebP keep transparency like PNG?
Yes. That’s the big advantage over JPG. Logos, icons and product cutouts keep their clear background after conversion, so you can swap a PNG for a WebP without redesigning anything.
Will converting PNG to WebP lose quality?
The tool saves WebP at about 92% quality, which is lossy but close enough that most images look the same on screen. Photos and gradients convert especially well. Very fine pixel art or tiny text can show slight softening, so check those at full size before you replace the originals.
Keep your PNG masters. WebP is for publishing; the PNG is what you go back to when you need to edit.
When should I stay with PNG?
- When a tool or client only accepts PNG.
- For source files you’ll keep editing.
- For older software and some email clients, which may not show WebP.
How do I use WebP images on my website?
Convert here, then upload the WebP files in place of the PNGs in your CMS or theme. Want them lighter still, or narrower for mobile? Compress Image adds a quality slider and a max width.
Is it safe?
Yes. The conversion runs entirely in your browser tab and your files never leave your device.
