Benefits

  • Smaller Than PNG: WebP files are typically 25-35% smaller than equivalent PNG files. This difference is especially noticeable for photographs and images with many colors.
  • Retains Transparency: Unlike JPEG, WebP fully supports alpha transparency. Your PNG images with transparent backgrounds remain transparency-enabled after conversion.
  • Lossless Option Available: Choose between lossy and lossless WebP encoding. Lossless mode preserves every pixel from your original PNG while still reducing file size.
  • Client-Side Security: All processing stays on your machine. Sensitive PNG files containing private graphics or data never traverse the internet during conversion.
