How Image Compressor Works
This tool runs entirely client-side: your image is never uploaded to a server. It loads your image into an HTML5 canvas element, then re-exports it using the browser's native canvas compression at a quality level you control with a slider.
For JPEG and WebP output, lowering the quality setting increases the amount of lossy compression applied, which reduces file size at the cost of some fine detail — the tool shows you the resulting file size in real time so you can find the right balance.
Because compression happens through the browser's built-in canvas.toBlob export function rather than a specialized image codec, results are broadly comparable to saving a "web quality" JPEG from any standard image editor.
