Why compress images at all?
Images are usually the largest files on a page, often half or more of its total weight. Unoptimised images are one of the most common reasons a site feels slow, and a slow site loses visitors before they read anything.
Page speed and the people waiting
Visitors abandon pages that take more than about three seconds, and each extra second raises the bounce rate sharply. Compressing images is the cheapest fix for that, and it takes about a minute.
Search rankings
Google uses page speed as a ranking signal on both desktop and mobile. Largest Contentful Paint, one of the Core Web Vitals, is usually decided by the biggest image on the page. Compressing it is one of the fastest routes to a better local SEO result.
Bandwidth and hosting
Smaller files mean less data sent to every visitor, which matters most on a phone connection and shows up directly in hosting costs on a busy site.
Need something else?
To change format, use the image converter. To change dimensions, use the image resizer. All of them are on the free tools page.
About compressing images
Is this image compressor really free?
Yes, 100% free with no limits. There are no sign-ups, no watermarks, and no hidden fees. Use it as many times as you need.
Are my images uploaded to a server?
No. All compression happens entirely in your browser using the Canvas API. Your images never leave your device, making this tool completely private and secure.
What image formats can I compress?
You can compress JPG, PNG, and WebP images. The output stays in the same format as the original. If you need to change formats, use our free Image Converter tool.
Will compressing my images reduce quality?
The quality slider lets you control the trade-off between file size and image quality. At 80% quality, most images look virtually identical to the original while being significantly smaller in file size.
How much can I reduce my image file size?
Results vary by image, but you can typically reduce file sizes by 40-80%. Large, uncompressed images from cameras or design tools often see the biggest reductions.
Can I compress multiple images at once?
Yes! You can select or drag-and-drop multiple images at once. All images will be compressed with the same quality setting, and you can download them individually or all at once.
Slow site, and not just the images?
Compression fixes one cause. If the whole thing feels sluggish, call and I will tell you what is actually holding it up. Websites are $99 a month.
