PNG to WebP: Slash File Sizes with the Modern Web Format
Key Takeaways
- WebP delivers 26% smaller file sizes than PNG for lossless images while maintaining identical visual quality and transparency support.
- All major browsers now support WebP, making it the optimal format for web performance and Core Web Vitals scores.
- WebP supports both lossy and lossless compression with alpha transparency — combining the best features of PNG and JPG in one format.
PNG files deliver excellent quality but their large file sizes can slow down websites significantly. WebP, developed by Google, provides the same lossless quality and transparency as PNG at dramatically smaller file sizes. Converting PNG to WebP is one of the easiest performance wins for any website, directly improving page load times, bandwidth costs, and search engine rankings.

Performance Gain
When to Convert PNG to WebP
Website Performance Optimization
Replace PNG assets with WebP to reduce page weight by 20-30%, improving Core Web Vitals scores and Google search rankings without sacrificing visual quality.
E-Commerce Product Images
Product images with transparent backgrounds benefit enormously from WebP — maintain crisp cutouts while loading faster on category pages with dozens of images.
Progressive Web Apps
PWAs need to be fast and lightweight. WebP assets reduce the app shell size and improve performance on mobile networks where bandwidth is limited.
CDN and Bandwidth Savings
High-traffic websites serving millions of images monthly can cut storage and bandwidth costs significantly by migrating PNG assets to WebP format.
Tips for PNG to WebP Conversion
Use lossless WebP mode to maintain exact pixel-for-pixel quality with your original PNG — perfect for graphics and icons.
For photographs that were saved as PNG, try lossy WebP at quality 80-90 for even greater file size reductions.
WebP supports animated images too — consider it as a replacement for animated PNG (APNG) assets.
Keep your original PNG files as source assets. WebP is ideal for distribution and web delivery.
All conversion happens entirely in your browser using the Canvas API. No images are uploaded to any server, ensuring your files remain private and secure.
