The Problem

PageSpeed Insights keeps telling you to serve images in next-gen formats. WebP delivers 25-35% smaller files than JPEG or PNG. But converting your existing image library is tedious.

Most tools process server-side (a privacy concern), watermark the output, or limit batch size behind a paywall.


Introducing WebP Cruncher

WebP Cruncher converts your entire image library to WebP in a single batch, using the Canvas API directly in your browser. No file size limits, no watermarks, no uploads — drag in your images and download a ZIP.

WebP Cruncher is completely free, requires no account or installation, and runs entirely in your browser. Your data never leaves your machine.


Key Features

  • Batch convert any number of images to WebP
  • Quality slider (0-100) with live file size preview
  • Supports PNG, JPEG, GIF (first frame), and BMP input
  • Downloads all converted images as a ZIP
  • 100% browser-based — no server uploads
  • No file size limits, no watermarks, completely free

Who Is It For?

Web developers, SEO professionals, site owners, and anyone improving page load speed.
