Convert PNG Images to WebP
This tool is built for a single purpose: converting PNG images into WebP format.
If you want smaller, faster-loading images without giving up transparency, this focused converter removes unnecessary options and delivers optimized WebP files in seconds.
Drop your PNGs, convert, and download everything at once.
Why Convert PNG to WebP?
PNG is a reliable, lossless format, but it often produces large files — especially for photos or detailed graphics.
WebP offers a modern alternative with:
- Much smaller file sizes compared to PNG
- Support for transparency, like PNG
- Wide browser support across modern devices
- Faster page loads for websites and web apps
For many web use cases, WebP is the best balance between size and quality.
Common Use Cases
-
Website Performance Optimization Replace heavy PNG assets with lightweight WebP images.
-
UI & Interface Graphics Keep transparency while reducing download size.
-
Static Sites & Frameworks Prepare optimized assets for Astro, Next.js, Nuxt, and similar stacks.
-
Batch Asset Modernization Update older PNG libraries to a modern web-friendly format.
-
Mobile & Performance-Sensitive Projects Reduce bandwidth usage without sacrificing clarity.

Important Notes
- Transparency is preserved. Transparent PNGs remain transparent in WebP.
- File size is usually much smaller than PNG, especially for complex images.
- Lossless vs lossy. WebP encoding is optimized for visual quality; existing PNG detail is preserved as well as possible.
- Metadata is removed. EXIF and ancillary metadata are typically stripped during conversion.
How This Tool Works
Everything runs entirely in your browser:
- PNG images are decoded and re-encoded as WebP using modern browser APIs.
- Conversion runs inside Web Workers to keep the interface responsive.
- Multiple images are processed in parallel for fast batch conversion.
- Final WebP files are bundled locally into a ZIP for easy download.
