PNG vs WebP Comparison

PNG

Lossless compression with transparency support. Best for graphics, logos, screenshots, and images with text. Universal browser support but larger file sizes. Consider using our PNG to ICO converter for creating favicons.

WebP

Modern format with superior compression developed by Google. Supports both lossy and lossless modes plus transparency. Up to 26% smaller than PNG with similar quality. For even better compression, try PNG to AVIF.

Lossy vs Lossless Mode

Lossy

Best for photos and complex images. Achieves 25-35% smaller files than PNG by discarding some data. Quality slider controls compression level. At 80-90%, the difference is virtually invisible to the human eye.

Lossless

Best for graphics, logos, and screenshots. Preserves every single pixel perfectly - no quality loss at all. Files are typically 10-25% smaller than PNG. Ideal when you need pixel-perfect output.

Quality Settings Guide

85-100%

High quality with excellent compression. Best for photos and detailed images. Barely visible difference from original.

70-84%

Good balance between quality and file size. Ideal for most web images, blog posts, and general use.

50-69%

Noticeable compression but still usable. Good for thumbnails, previews, or when file size is critical.

Below 50%

Heavy compression with visible artifacts. Only use when file size is more important than quality. Consider our WebP compressor for more control.

Frequently Asked Questions

WebP offers superior compression compared to PNG, typically reducing file sizes by 25-34% while maintaining similar visual quality. This means faster website loading times, lower bandwidth usage, and better user experience. Unlike JPG, WebP also preserves transparency. For the best results, combine with our Image Resizer to optimize dimensions too.

Yes! Unlike JPG, WebP fully supports transparency (alpha channel). When you convert a PNG with transparent areas to WebP, the transparency is preserved in both lossy and lossless modes. This makes WebP an excellent choice for logos, icons, and graphics that need transparent backgrounds.

Use lossless mode when you need pixel-perfect quality: graphics with text, logos, screenshots, diagrams, or any image where you'll zoom in closely. Lossless WebP is typically 10-25% smaller than PNG while preserving every detail. For photos, lossy mode at 85% is usually the better choice for file size savings.

For most purposes, 80-90% quality offers an excellent balance between file size and visual quality. For photos, 75-85% usually works great. For graphics with solid colors, you can often use 90-100% without much file size increase. Use our WebP Analyzer to check the results.

Yes, each file can be up to 20MB in size, and you can upload up to 10 files at once. This limit helps ensure fast processing. For larger files, consider using the resize option to reduce dimensions first, or try our PNG Compressor before converting.

Files are temporarily stored only during the conversion process and are automatically deleted within 24 hours. Most conversions happen directly in your browser for privacy. We don't keep copies of your images and don't use them for any other purpose.

WebP is now supported by all major browsers including Chrome, Firefox, Safari, Edge, and Opera. As of 2024, over 97% of users have WebP support. For the few remaining users, you can use the HTML picture element to provide PNG fallbacks.
