  4. Compare the original and compressed photo side by side, then press Download.

Frequently asked questions

Is this image compressor free?

Yes. It is completely free with no sign-up and no limit on the number of images.

Are my photos uploaded anywhere?

No. Compression happens on your own device, so your photos stay private and processing is instant.

Why compress an image to 50KB or 100KB?

Many job applications, exam forms, and government portals only accept photos under a set size such as 20KB, 50KB, or 100KB.

Can I change the image format?

Yes. Choose JPG, WebP, or PNG from the Output format menu, for example to turn a heavy PNG into a light JPG.

Can I resize the photo too?

Yes. Resize by percentage, or enter a custom width and height. Keep aspect ratio on so the photo does not look stretched.
