Compress Images Online — Free, No Signup
Big image files are the number one reason pages load slowly. Whether it is a phone photo you want to share, a product shot for your shop, or a banner for your website, oversized files mean slow uploads, wasted storage, and visitors who give up waiting. Our free image compressor shrinks JPG, PNG, WebP, AVIF, GIF and BMP files – often by up to 80 percent – while keeping them looking sharp. No signup, no watermarks, no funny business: just drop your images in and download the smaller versions in seconds.

Frequently asked questions
Will compressing reduce the quality of my images?
You would be hard-pressed to spot the difference. Our compressor uses smart encoding that strips out data your eyes cannot see, so files get dramatically smaller while the image still looks crisp. For everyday photos and web graphics, the result is visually identical to the original.
Which formats can I compress?
All the popular ones: JPG, PNG, WebP, AVIF, GIF and BMP. Upload any of them and download a smaller version in the same format.
Is it really free?
Yes – completely free, with no signup and no watermarks. Compress as many images as you like, whenever you like.
What happens to my files after I upload them?
Your files are encrypted while they are transferred, and they are permanently deleted from our serverZZZMARKEs within 1 hour. We never sell, share, or reuse your images – what you upload stays yours.
