Why compress images at all?

Large image files slow down websites, eat up storage, and make email attachments fail. Compressing an image the right way reduces file size dramatically without any visible drop in quality. A 5 MB photo can shrink to 500 KB and still look sharp on any screen.

Our free image compressor uses modern browser APIs to shrink your files locally. Nothing gets uploaded to a server, so your photos stay private and the compression is instant.

Frequently Asked Questions

Does compressing an image lose quality?

With the right settings, no visible quality loss. At 70-80% quality, most people cannot tell the difference between the original and the compressed version, but the file can be 3-5x smaller.

Is this image compressor really free?

Yes. No sign-up, no trial, no watermarks, no file limits. Compress as many images as you want.

Are my images uploaded to a server?

No. All compression happens in your browser using client-side JavaScript. Your images never leave your device, which also makes the process much faster.

What file formats are supported?

JPG, PNG, and WebP. You can also convert between formats while compressing - for example, turning a large PNG into a much smaller WebP.

What's the best way to compress images without losing quality?

The best way is to use a quality setting between 70-85%. Below 70% you start seeing artifacts around edges and text. Above 85% the file size savings drop off. For photos, 80% is the sweet spot. For graphics with text or sharp edges, use PNG or WebP instead of JPG.

Can I losslessly compress images?

Yes. Losslessly compressing images means reducing file size with zero quality loss. PNG and WebP both support lossless compression. JPG is always lossy. If you need the exact original pixels preserved, stick with PNG or WebP lossless mode.

How do I compress images for web without losing quality?

For web images, convert to WebP at 80% quality. WebP gives you 25-35% smaller files than JPG at the same visual quality. Most modern browsers support it, so your page loads faster without any visible loss. Our tool does this in one click.
