Upload your .png file by dragging it into the upload area or clicking to browse.
Choose your output settings. The default settings work great for most files.
Click Convert and download your .webp file when it's ready.
PNG's lossless quality and transparency support make it essential for web graphics, but file sizes can be substantial. WebP delivers the same capabilities with dramatically smaller files—typically 30-50% reduction while preserving transparency and visual quality.
Our PNG to WebP converter creates optimized images that maintain PNG's features while loading significantly faster. For websites serving PNG graphics, logos, and UI elements, this conversion is one of the most impactful optimizations available.
File size reduction is dramatic. WebP's superior compression achieves 30-50% smaller files than PNG at equivalent quality. For a website loading 20 PNG images, that's substantial bandwidth savings and faster page loads.
Transparency preserves completely. Unlike JPG conversion which loses transparency, WebP supports full alpha channel. Logos, icons, and graphics with transparent backgrounds convert perfectly.
Web performance metrics improve. Google's PageSpeed Insights specifically recommends WebP. Converting PNG assets to WebP directly improves Core Web Vitals scores and search rankings.
WebP supports both lossy and lossless compression. For PNG conversion, we default to lossless WebP—preserving exact quality while achieving significant size reduction. Lossy mode is available for even smaller files with imperceptible quality loss.
Transparency (alpha channel) transfers directly. Animated PNGs (APNG) convert to animated WebP where supported. Color profiles and metadata preserve through conversion.
Lossless WebP is truly lossless—pixel-identical to the PNG source. File sizes are still 20-30% smaller due to WebP's superior compression algorithm. Lossy mode achieves greater reduction with some quality tradeoff.
