Image Compressor

Large images slow down websites, eat through storage, and frustrate users on mobile connections. Image compression solves this by reducing file size while preserving visual quality — and the best part is that modern browsers can do it natively using the Canvas API, with no server uploads required.

This compressor works entirely on your device. Drop in one or many images, dial in your preferred quality level or target file size, and download the results individually or as a batch zip. The side-by-side preview lets you visually confirm that the compressed version still looks sharp before you commit. JPEG and WebP respond especially well to quality-based compression, while PNG compression is lossless through re-encoding.
