Shrink PNG files by up to 80 %- convert to WebP free, browser-based, no upload.
Open WebP ConverterWebP replaces PNG with dramatically smaller files at the same visual quality. For websites and web apps, serving WebP instead of PNG means faster page loads, lower bandwidth costs, and better Core Web Vitals scores. All major browsers have supported WebP since 2020, making the switch risk-free for most projects.
WebP lossless mode produces files 26 % smaller than PNG on average. WebP lossy mode at quality 80 produces files that look identical to PNG but are up to 80 % smaller. SammaPix lets you choose the quality level.
| Format | File Size | Quality | Compatibility | Use Case |
|---|---|---|---|---|
| PNG | Large | Lossless | Universal | Logos, graphics, screenshots, editing source |
| WebP | Smallest | High (lossy or lossless) | All modern browsers | Web images, performance optimization |
| JPG | Small–Medium | High (lossy) | Universal | Photos, email, social media |
| AVIF | Smallest | Excellent | Modern browsers only | Next-gen web images |

Does converting PNG to WebP lose quality?
It depends on your settings. WebP supports both lossy and lossless modes. In lossless mode the output is pixel-perfect but only 26 % smaller. In lossy mode at quality 80–90 the visual difference from the original PNG is negligible while file size drops 60–80 %.
Is WebP supported in all browsers?
WebP is supported in Chrome, Firefox, Safari (since 2020), Edge, and all major mobile browsers. If you need to support Internet Explorer 11 (which is now end-of-life), use JPG instead.
Should I convert my PNG logo to WebP?
If your logo contains transparency (alpha channel), WebP handles transparency just like PNG- so yes, converting is safe. Just use WebP lossless mode to preserve crisp edges.
Can Next.js and WordPress serve WebP automatically?
Next.js Image component converts and serves WebP automatically. WordPress with a plugin like Imagify or ShortPixel can do the same. Converting your originals to WebP first gives you maximum control.
