Compress images without losing your privacy
This tool compresses JPG and PNG images entirely in your browser using the HTML canvas — your files are never uploaded to a server. Drag the quality slider to trade a little visual fidelity for a much smaller file, then download the result instantly.
Why compress images?
Smaller images load faster, improve your website’s SEO and Core Web Vitals, and make email attachments and uploads quicker. For most photos a quality of 70–80% cuts the file size dramatically with little visible difference.
