WebP Image Optimizer

What It Does

Converts JPG, PNG, GIF, BMP, TIFF, and existing WebP files into fresh WebP exports directly in the browser. You can tune compression quality, optionally downscale large images, and compare the original file size against the optimized output before downloading.

Why WebP

WebP delivers 25–35% smaller files than JPEG at equivalent visual quality and supports lossless, lossy, and transparency in a single format. All major browsers have supported it since 2020.

How It Works

When you add an image, the tool reads the file locally with the browser File API, draws it into an off-screen canvas, then exports a new image/webp file with your selected quality setting. If you provide a max width or height, it resizes the image before encoding so you reduce both pixel dimensions and file weight in a single pass. Nothing is uploaded or processed on a remote server.
