Who uses this tool

Web developers

Unoptimized images are the most common cause of slow page loads. Compress images before uploading to your CMS or CDN to hit Core Web Vitals targets and improve SEO scores.

E-commerce sellers

Product listings with heavy images load slowly on mobile, increasing cart abandonment. Compress product photos to keep pages fast while maintaining sharp visual quality.

Email marketers

Most email clients limit embedded image sizes. Compress images before inserting them into campaigns to avoid clipped emails and improve deliverability.

Content creators

Thumbnails, blog graphics, and social media images need to load instantly. Compress images once and reuse them across platforms without re-optimizing each time.

Frequently asked questions

Does compression reduce visible quality?

At quality settings of 80–90, compression is visually lossless for most images. The default setting balances file size and quality automatically. You can adjust the quality slider to find the right balance for your specific use case.

What file formats are supported?

JPG, PNG, and WebP files up to 10 MB are supported. The output format matches the input format.

How much can it reduce file size?

Typical reductions are 50–80% for JPG and PNG files without visible quality loss. WebP compression is more efficient than JPG at equivalent visual quality, so converting to WebP before compressing gives the best results.

Is it free to use?

Yes. Image compression is completely free with no sign-up required. No credits, no watermarks, no limits.

How is this different from just lowering JPEG quality in Photoshop?

Our compressor analyses each image individually and finds the optimal quality level that minimises file size while preserving perceived sharpness. It also strips unnecessary metadata and applies format-specific optimisations that a simple quality slider in Photoshop does not.
