For users in the USA, UK, and other English-speaking markets, the tool supports a simple workflow: upload one or more PNG images, choose a quality level, optionally resize the images, and download the resulting WebP files. The conversion runs in the browser and does not require a separate image conversion API.

Why Convert PNG to WebP?

PNG is useful when lossless image quality and transparency are important, while WebP supports both lossy and lossless compression and can also store transparency. Converting a PNG to WebP may reduce the file size for a website, blog, online store, documentation page, or other web project, although the final size depends on the image and selected quality.

The quality control lets you choose a practical balance between visual detail and file size. Keeping the original dimensions is available when you only want a format change, while the resize options can reduce dimensions for thumbnails, content images, or other web assets.

  • Transparency support: WebP can retain alpha transparency when the browser's encoder supports it.
  • Preview before conversion: review selected PNG files before processing.

How to Convert PNG to WebP

  1. Select one or more PNG files, or drag them into the upload area.
  2. Review the image previews and choose your preferred WebP quality.
  3. Keep the original dimensions or select a resize option.
  4. Click Convert to WebP and download the generated WebP files.

PNG to WebP for Websites and Web Performance

WebP is commonly used for website images because it supports modern compression and can reduce image file size compared with many PNG images. Smaller image files can be useful for pages where image weight matters, but the best quality setting depends on the source image and the visual result you need.

When Should You Keep PNG?

Keep PNG when you need a lossless source, pixel-accurate graphics, or workflows that specifically require PNG. When your project accepts WebP, converting PNG images to WebP can be a practical way to prepare web-ready assets.
