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.

Whether you are building a web page, preparing photos for email, or trimming a large image library, file size matters. The Image Optimizer compresses JPG, PNG, WebP and AVIF files so they load faster and use less bandwidth — all inside your browser, with no server round-trip.

Because every byte of processing happens client-side, your pictures never leave your device. That privacy makes it safe to work with confidential product shots, internal documents, screenshots and personal photos you would rather not upload to a third party.

How to Optimize an Image

  1. Drop one or more images into the upload area, or click to browse files from your device.
  2. Choose the target format and a quality level. A quality setting in the 75 to 85 range compresses most photos strongly without visible losses.
  3. Click Optimize, then download individual files or a single ZIP archive containing all of your processed images.

Practical Use Cases

Optimize product images before uploading them to a shop, shrink email attachments that would otherwise bounce due to size limits, archive large photo collections into smaller copies, and improve your Core Web Vitals by serving lighter images — better load time, budget, and user experience all at once.

Image optimizer — common questions

Which formats does the optimizer support?

It handles JPG, PNG, WebP and AVIF. You set a target format and quality, and the tool compresses the selected files accordingly, all in-browser.

Are my images uploaded to a server?

No. The entire optimization runs client-side in your browser, so your pictures never leave your device. That is why the tool is safe for private and confidential materials.

What quality setting should I pick?

For photos, a quality level around 75 to 85 gives a strong size reduction against minimal visual difference. You can compare the output to the original size and tune the value if needed.
