How it works

  1. 1Select a PNG file.
  2. 2Adjust WebP quality and width if needed.
  3. 3Download the converted WebP image.

Privacy and limits

  • Transparency is preserved when the browser supports it.
  • Animated PNG files export as a still frame.
  • Very large PNGs may take longer.

Why convert PNG to WebP

WebP can preserve transparency while reducing bytes compared with many PNG screenshots and graphics.

This page is focused on PNG input so the workflow stays clear for assets that start as screenshots, icons or transparent graphics.

Common use cases

  • Shrinking transparent web graphics
  • Optimizing documentation screenshots
  • Creating smaller social preview assets from PNG designs

Format notes

  • Transparency support depends on browser WebP export.
  • Flat illustrations often compress well as WebP.
  • Keep PNG if exact pixel output is required.

Original test sample

  • Try WebP quality 84 on a screenshot and compare text edges at 100% zoom.
  • For transparent graphics, verify the background remains transparent after download.

Frequently asked questions

Are my images uploaded?

No. ImgShrink processes selected images in your browser and does not upload them to a server.

Will conversion keep animation, metadata or transparency?

Browser canvas export usually creates a still image and does not preserve metadata. Transparency is kept only by formats and browsers that support it.

Why is an output format unavailable or different?

The browser controls image decoding and export support. Some browsers may not export AVIF or may flatten unsupported transparency.

Source and compatibility notes

This tool works in the browser, so output support depends on what your browser can read and export.
