Why use a PNG to WebP converter online
PNG files are significantly larger than WebP files. Converting PNG to WebP reduces file size by 50% to 80% while maintaining identical visual quality. This makes your website load dramatically faster — which directly improves your Google search rankings, Core Web Vitals scores, and user experience for visitors across the UK, USA, Europe, and worldwide.
Google officially recommends WebP as the preferred image format for websites. If you are running a WordPress site, Shopify store, or any web project in the UK or Europe and still using PNG images, converting to WebP is one of the most impactful improvements you can make for both speed and SEO.
What happens when you convert here
Unlike tools like TinyPNG or iLoveIMG that upload your images to their servers, Firaa converts your PNG to WebP entirely inside your browser. Your image never leaves your device — no upload, no server, complete privacy.
The tool uses your browser’s canvas engine to encode the PNG in WebP format at high quality. The result is a significantly smaller WebP file that looks identical to the original PNG on any modern browser including Chrome, Firefox, Safari, and Edge.
How much smaller does WebP make your PNG files
The file size reduction from PNG to WebP is typically more dramatic than JPG to WebP because PNG files start out much larger. These are typical results:
Website logos and graphics — A PNG logo at 200KB typically converts to WebP at 40KB to 80KB — a 60% to 80% reduction. For a website with 20 graphic elements this adds up to massive bandwidth savings and dramatically faster page loads for UK and European visitors.
Product images for UK and European ecommerce — Shopify and WooCommerce stores serving customers across the UK, Germany, France, and the Netherlands see significant conversion rate improvements when pages load faster. Converting product PNGs to WebP is one of the fastest ways to improve ecommerce page speed.
Blog post images and infographics — PNG infographics and diagrams often saved at 1MB to 3MB convert to WebP at 200KB to 600KB. This alone can reduce your page load time by 2 to 3 seconds for readers on mobile connections across Europe.
WordPress featured images — Converting all WordPress featured images from PNG to WebP before uploading is one of the most effective ways to improve your Google PageSpeed score from amber to green — essential for ranking well in competitive UK and European search markets.

PNG to WebP conversion for WordPress websites
WordPress has supported WebP uploads natively since version 5.8. For new images, convert your PNG to WebP here before uploading to your WordPress media library — this gives you full control and zero plugin overhead.
For existing PNG images already uploaded to your WordPress site, plugins like Imagify, ShortPixel, or Smush can batch convert them to WebP automatically. These are particularly popular with UK and European WordPress developers who need to meet Google’s Core Web Vitals requirements for search ranking.
After converting your images to WebP, also enable browser caching and use a CDN with servers in the UK and Europe for the fastest possible load times for your European visitors.
Does every browser support WebP
Yes. WebP is supported by all major browsers used across the UK, Europe, USA, and worldwide — including Chrome, Firefox, Safari 14+, Edge, and Opera. Over 97% of all internet users globally are on a WebP-compatible browser. There is no reason to avoid WebP for any modern website targeting UK or European audiences.
Frequently asked questions about PNG to WebP conversion
Will converting PNG to WebP affect image transparency?
WebP supports transparency just like PNG. If your PNG has a transparent background, the converted WebP file will also have a transparent background preserved perfectly. This makes PNG to WebP conversion ideal for logos, icons, and UI elements that need transparency — you get all the benefits of WebP with no loss of transparency support.
How much will converting PNG to WebP improve my Google PageSpeed score?
Google PageSpeed Insights specifically flags PNG images as opportunities to serve in next-gen formats like WebP. Converting your PNGs to WebP typically removes this warning entirely and can improve your PageSpeed score by 15 to 40 points depending on how many PNG images your page has. This is particularly impactful for UK and European websites competing for search rankings in Google’s mobile-first index.
Can I use WebP images on my Shopify store?
Yes. Shopify fully supports WebP image uploads. Converting your product PNG images to WebP before uploading to Shopify significantly improves your store’s page load speed — which directly impacts conversion rates and Google Shopping rankings for UK and European customers.
Is my image safe — does Firaa upload it to servers?
No. Your PNG is converted entirely inside your browser using JavaScript. Nothing is uploaded to any server at any point. Your images stay completely private on your device.
What is the difference between PNG to WebP and JPG to WebP conversion?
PNG to WebP typically produces more dramatic file size reductions than JPG to WebP because PNG files start out much larger due to their lossless compression. Both conversions produce excellent results. Use our JPG to WebP Converter for photographs and our PNG to WebP converter for graphics, logos, and images with transparency.
How is Firaa different from other PNG to WebP converters?
Most online converters including TinyPNG upload your images to their servers. Firaa converts entirely in your browser — completely private, faster with no upload time, and free with no account required.
