Image Compressor
Shrink JPG, PNG, and WebP images to a fraction of their size — free, with live before/after sizes and zero uploads.
Large image files slow down websites, eat mobile data, and bounce off email attachment limits. Our free image compressor reduces the file size of your JPG, PNG, and WebP images dramatically while keeping them looking sharp. Just drop in your images, move the quality slider to the level you like, and download the smaller files — it is that simple.
You get full control over the trade-off between size and quality. The quality slider runs from 35 to 95 percent, and every result shows its original and compressed size side by side with the exact percentage saved, so you can see precisely what you are getting. You can also downscale oversized photos at the same time with the max-width option — handy for camera shots that are far bigger than any screen needs — and choose JPEG or WebP as your output format for the smallest possible files.
Batch compression saves even more time: process up to 12 images in one go, each with its own download button. And because compression runs entirely in your browser, your photos are never uploaded to a server, never stored, and never seen by anyone else. No signup, no watermarks, no hidden limits.

Frequently asked questions
Will compression reduce quality?
Some quality is traded for size — that is how compression works — but at the default 78% the difference is barely visible for photos and screenshots. If you need pristine detail, raise the slider toward 90%; if you need the tiniest file, lower it toward 50%.
Should I convert PNG to JPG?
Often, yes. PNG files are much larger than JPGs for photos and screenshots. If your PNG has no transparency you need to keep, compressing it to JPEG output can shrink it by 70–90% with barely noticeable change.
How many images can I compress at once?
Up to 12 images per batch. Each compressed image gets its own preview, size comparison, and download button. You can run as many batches as you like.
Are my images private?
Yes. Compression runs 100% in your browser — your images are never uploaded, stored, or seen by anyone else.
