Best practices

  • Use a quality between 70% and 80% for most web images.
  • Start with a high-resolution original for the best results.
  • Compress photos before uploading them to your website.
  • Lower the quality further for thumbnails and previews.
  • Keep an original copy in case you need full quality later.
  • Check the new KB size to confirm it meets your limits.

Frequently asked questions

Is this JPEG optimizer free to use?

Yes. Our tool is completely free with no hidden charges, watermarks, or registration requirements of any kind.

How does the compression work?

The JPEG Optimizer uses your browser's local processing power to redraw and re-encode the image at a more efficient bit rate based on your quality selection.

Will my images be saved on your server?

No. We use client-side technology, so your photos stay on your computer. Your privacy is always our top priority.

Can I convert JPEG to JPG here?

This tool optimizes existing files. For specific extension changes, use a dedicated JPEG to JPG converter to ensure standard web compatibility.

Does this tool support WebP?

Yes. You can optimize individual WebP files here, or use a bulk WebP conversion tool for handling large batches of images at once.

What is the best quality setting for the web?

For most websites, a quality setting between 70% and 80% gives the best balance between small file size and high visual quality.

Can I use this on my mobile phone?

Absolutely. Our optimizer is fully responsive and works smoothly on Android, iPhone, and tablet browsers.

Does compression remove EXIF data?

Yes. Our tool strips unnecessary metadata, like camera settings and GPS location, to further reduce the file size.

Is there a limit on file size?

Since processing happens in your browser, the limit depends on your device's memory. We recommend files under 20MB for the smoothest experience.

Why is my optimized file larger than the original?

This is rare. If an image is already highly compressed, re-saving it at a high-quality setting may increase the size. Choose a quality level lower than the original for best results.
