Convert PNG to WebP online

Turn heavy PNG files into lightweight WebP images while keeping transparency. WebP typically produces far smaller files than PNG, making your pages load faster. Drop your PNGs below to convert them privately in your browser.

Output is set to WebP. Drag in your PNG files to convert them.

How it works

  1. Drag your PNG files into the upload area.
  2. CompressEasy converts each PNG to WebP automatically.
  3. Download the smaller WebP files individually or as a batch.

Why convert PNG to WebP

PNG is lossless and often large. WebP supports both lossy and lossless modes plus transparency, so you usually get dramatically smaller files that still look identical, which is ideal for the web.

Transparency is preserved

WebP keeps the alpha channel, so transparent logos, icons, and graphics convert cleanly without a background being added.

Batch convert in seconds

Drop a whole folder of PNGs and convert them all at once, then download the WebP results together. Everything stays on your device.
