What is png to webp converter free?
PNG files are lossless and large - great for quality but slow for web. WebP delivers the same transparency support as PNG but with dramatically smaller file sizes, typically 25-80% smaller. Vakru converts PNG to WebP entirely in your browser with no upload. Free, no signup, no watermark.
How it works
Cut PNG file size by 50%+ while keeping transparency intact using WebP - the modern web image format with the best compression.
Upload your PNG
Drop one or several PNG files into the converter. We work entirely inside your browser.

💡 Pro Tips
WebP is the best format for transparent web images
It's smaller than PNG and supports transparency - making it ideal for logos, icons, and UI assets on websites.
Use 80% quality for photos, 90%+ for UI assets
Photos look great at 80% WebP quality. Sharp icons and UI elements benefit from slightly higher settings to preserve crisp edges.
Bulk convert entire icon libraries
Drop in 50 PNGs and get all WebPs back as a ZIP - perfect for migrating design assets or icon sets.
All modern browsers support WebP
Chrome, Firefox, Safari 14+, and Edge all support WebP. It's safe to use as your primary web format.
