About the Image Optimizer

The Image Optimizer compresses JPG, PNG, WebP and AVIF files directly in your browser. All processing happens client-side: files are never uploaded to a server, which makes the tool safe for private images, screenshots and product photos.

How to use it

  1. Drop one or more images into the upload area, or click to browse files from your device.
  2. Choose a target format and quality level. Most photos compress well at quality 75-85.
  3. Click Optimize, then download individual files or a ZIP archive containing every processed image.

When to use it

Use the optimizer before uploading images to a website, sending photos by email, or archiving large image libraries. Smaller files mean faster page loads, lower bandwidth costs and better Core Web Vitals scores.

Privacy

Because optimization runs entirely in your browser, no file ever leaves your device. You can safely process confidential product photos, internal documents and personal pictures.
