PNG to WebP converter – compress without losing transparency

PNG is a lossless format that produces relatively large files — ideal for editing but heavy for web delivery. WebP typically produces files 50–70% smaller than PNG at comparable visual quality, making it one of the most effective image optimizations for websites.

WebP supports both lossy and lossless compression modes, alpha transparency, and millions of colors. It is supported by all modern browsers: Chrome, Firefox, Safari 14+, and Edge. Lossy WebP at quality 80 is visually indistinguishable from lossless PNG for most images.

If transparency is important, WebP preserves it from the original PNG. Google PageSpeed Insights recommends serving images in next-gen formats like WebP for better Core Web Vitals scores.

All processing happens locally in your browser — nothing is sent to any server. No registration, no limits, no watermarks.

Businesses, developers, and creators worldwide rely on image format compatibility. Whether you are preparing product images for Amazon, eBay, Etsy, Shopify, optimizing graphics for WordPress, Wix, Squarespace, or converting photos for government portals worldwide, having the right format matters.

Modern web standards increasingly favor efficient formats. Google PageSpeed Insights and Core Web Vitals metrics reward pages that use optimized images. Converting PNG to WebP can directly improve your Largest Contentful Paint (LCP) score, which impacts both search rankings and user experience.

For email marketing campaigns and social media, WebP provides excellent compression while maintaining visual quality. Whether you are a freelancer, small business owner, or enterprise user, this converter handles your image conversion needs reliably and securely.

• Start with quality 85 – this is typically the sweet spot for WebP compression, offering significant file size reduction with minimal visible quality loss.
• Batch convert for efficiency – if you have many PNG files, use the batch conversion feature to process them all at once. This saves considerable time compared to one-by-one conversion.
• Compare before downloading – use the live preview to compare the original PNG with the WebP result. Adjust quality settings until you find the right balance for your specific use case.
• Keep your originals – always save a copy of your original PNG files. Lossy compression is irreversible, so having the originals allows you to re-convert with different settings later.

The quality slider lets you set a value from 60% to 95%. Higher values mean better image quality but larger file sizes.

• 80% (default) – a good balance for most use cases. The visual difference compared to lossless PNG is virtually imperceptible while file size drops by 50–70%.
• 85–90% – for product photography and portfolios where quality is the priority.
• 60–70% – when minimizing file size is the priority, e.g. thumbnails in category grids.

At 80% quality, WebP produces results that are visually indistinguishable from lossless PNG for most photographic content. For pixel-perfect accuracy, use WebP lossless mode if available.

PNG is lossless and produces relatively large files. WebP provides substantial savings:
