PNG to WebP Converter

Convert PNG images to WebP right in your browser — free, fast and private.

What is PNG to WebP conversion?

This tool converts PNG images into the WebP format, entirely in your browser with no upload. PNG is a lossless format with transparency support, so quality never degrades when you save. It is ideal for logos, icons, screenshots with text and images with transparent backgrounds, but files tend to be larger. WebP is a modern web format from Google that supports both transparency and higher compression, typically 25–35% smaller than JPG or PNG. It is great for speeding up websites, though a few older programs may not support it.

How to use it

  1. Select or drop in your PNG image.
  2. The tool converts it to WebP locally, instantly.
  3. Click Download to save the WebP file.

When should you convert PNG to WebP?

PNG files are common for graphics and screenshots, but their lossless compression can make photos unnecessarily large.

Convert PNG to WebP when you want faster-loading web pages: WebP is typically 25–35% smaller than PNG while keeping both quality and transparency. It is perfect for website images; if your audience uses older software without WebP support, use JPG or PNG instead.

Frequently Asked Questions

Are my images uploaded?

No. The conversion runs entirely in your browser using the Canvas API. Your images are never sent to a server or stored, so it is safe for private photos.

Does converting PNG to WebP reduce quality?

WebP is a lossy format, so the image is compressed based on the quality setting and may lose a little detail. In practice the difference is usually invisible, and you get a much smaller file.

Is transparency preserved?

Yes. WebP supports transparency, so any transparent background in the original is kept.

Can I convert many images at once?

You can convert images one at a time; everything runs locally, so speed depends on your device. For large batches, a desktop browser works best.
