How it works

PNG to WebP in 4 steps

  4. Download the WebP.

When to use it

WebP is the only mainstream format that gives you PNG-style transparency at JPG-style file sizes. Convert your PNGs locally - transparency is preserved and nothing is uploaded.

  • Serve logos and UI graphics with transparency at a fraction of PNG size.
  • Speed up landing pages that use large transparent hero images.
  • Convert sticker and asset packs in one batch with Pro.

Format & quality notes

  • Transparency survives the conversion - WebP supports full alpha channels.
  • Graphics with flat colors and text compress extremely well; expect 60-80% size reductions.
  • Photographic PNGs shrink the most, since PNG is a poor fit for photos to begin with.
