Image Compressor
Compress PNG, JPG, or WebP images instantly in your browser without losing quality.
About this tool
The Image Compressor reduces the file size of PNG, JPG, and WebP images by adjusting their compression quality. A simple slider lets you dial in the trade-off between file size and visual quality, with a live preview and size comparison so you can make an informed decision before downloading.
Image optimization is one of the highest-impact front-end performance improvements you can make. Images are typically the largest assets on a webpage, and unoptimized images slow down load times, increase bandwidth costs, and hurt SEO scores. Even a 50% reduction in image size often produces no visible quality difference to the human eye.
This tool processes images entirely in your browser using the HTML5 Canvas API. No files are uploaded to any server. The compression is lossy for JPEG and WebP formats (adjustable quality) and lossless for PNG. For production workflows, consider integrating a build-time image optimization step alongside tools like this.
