About this image compressor
Large images slow down websites and bounce off email attachment limits. This compressor shrinks JPEG, PNG and WebP file sizes with an adjustable quality slider and shows exactly how many kilobytes each file saves before you download.
How to use
- Add your images and preview the originals.
- Drag the quality slider to balance size and sharpness.
- Click Compress and compare each before/after pair, then download.
Common use cases
- Compress JPEG and WebP photos before attaching them to an email with a size cap.
- Shrink hero images so a landing page can hit Core Web Vitals LCP targets.
- Reduce a folder of product photos to send to a marketplace or print shop.
Every file is processed locally in your browser. Nothing is uploaded, logged or stored, and there is no account to create.
