Why convert PNG to WebP?

WebP delivers comparable visual quality to PNG at a much smaller file size, and it still supports alpha transparency. Converting PNG to WebP speeds up your site, improves Core Web Vitals, and reduces bandwidth — perfect for blogs, ecommerce, and landing pages.

Best use cases

  • Logos, UI assets, and screenshots that need transparency
  • Product images and hero graphics on speed-focused sites
  • Mobile-first experiences where data usage matters
  • CDN pipelines serving next-gen formats automatically

When to keep PNG

  • Legacy apps, editors, or CMS themes that don’t handle WebP
  • Print workflows or toolchains that specifically require PNG
  • Pixel-perfect assets where lossless PNG is mandated

How to convert PNG to WebP (step by step)

  1. Drag & drop your PNG files into the upload area.
  2. Click Convert & Download ZIP to get WebP output.
  3. Unzip and use the optimized images on your site or app.
Tip: Resize first with the Image Resizer or fine-tune size with the Image Compressor for even smaller files.

PNG vs WebP: what changes?
