About JPG to WebP

WebP is a modern web image format developed specifically to replace aging JPEG and PNG formats. According to Google's data, WebP lossy images are 25% to 34% smaller than comparable JPEG images at equivalent structural similarity (SSIM) visual quality.

Upgrading your website's photo assets from traditional JPG to WebP is one of the highest-impact optimizations you can perform to lower Largest Contentful Paint (LCP) times, reduce mobile data usage, and satisfy Google PageSpeed Insights criteria.

Our in-browser converter allows you to batch-convert full libraries of photos without sending confidential imagery or client photos over the network. Everything processes locally inside your browser memory.

Common Use Cases

Website Speed OptimizationReplace legacy JPG banner and product imagery with WebP to dramatically decrease initial page weight.
Blog & Editorial PublishingConvert high-resolution article imagery to WebP before uploading to WordPress, Webflow, or Shopify.
Mobile App GraphicsBundle lightweight WebP assets inside iOS and Android applications to keep installation size down.
Email Marketing AssetsSpeed up newsletter render times by converting header and hero visuals to WebP for modern email clients.
Notes & Format Guidelines
  • Very old web browsers (e.g., Internet Explorer 11) do not support WebP, though 97%+ of modern global browsers do.
  • Re-encoding an already heavily degraded JPEG to WebP cannot recover original details.
  • Batch processing is recommended for up to 20 files per run.
