Max file size: 10MB per file | Supports multiple files
Lower quality means smaller files. 90 is a good default for most images; choose Lossless for screenshots, logos and text that must stay pixel-perfect. The setting applies when you convert.
Easily convert your .png files to .webp format using our fast, browser-based PNG to WebP converter. WebP was created by Google specifically for the web: at the same visual quality, a WebP image is typically 25–35% smaller than the PNG it replaces — which means faster page loads, better Core Web Vitals scores and less bandwidth used on every visit.
This tool gives you control that most converters hide: pick a quality level for the smallest possible files, or switch on Lossless when every pixel matters. No data is uploaded — all processing happens locally in your browser for complete privacy and speed.
No registration, no watermarks — just reliable image conversion that works when you need it. Try our PNG to WebP converter today and make your pages lighter in seconds!
PNG is a superb format — lossless, sharp, and transparent — but it is heavy. A single full-screen PNG screenshot or product image can weigh several megabytes, and every extra kilobyte slows your page and hurts your search rankings. WebP was designed to fix exactly that: Google's own comparison study found lossless WebP images are 26% smaller than PNGs on average, while lossy WebP keeps transparency that JPEG cannot offer at all. This converter turns your .png files into web-ready .webp files in seconds, and it can batch-convert a whole set in one go.
All processing happens locally in your browser, so no data is uploaded and your images never leave your computer — a real benefit when the files are screenshots, designs or anything sensitive. Whether you are a developer optimising a site, a blogger lightening a post, or a shop owner speeding up product pages, the tool is free with no registration.
Yes. WebP supports full alpha-channel transparency just like PNG, in both its lossy and lossless modes — transparent logos and cut-outs convert cleanly.
Typically 25–35% smaller at high quality settings, and around 26% smaller in lossless mode. Screenshots and graphics with flat colours often shrink much more.
90 is a strong default — visually identical for almost all images. Use 95–100 or Lossless for text-heavy screenshots and logos; drop to 75–85 for decorative images where small size matters most.
No. Everything runs in your browser for complete privacy and speed.
