About the Online Image Compressor
Image compression is one of the most frequent needs in online work and e-commerce: oversized JPG, PNG and WebP files slow down page loading and hamper upload efficiency. This tool dramatically reduces file size with smart encoding and quality balancing while keeping the visual result almost indistinguishable from the original, with batch processing and one-click download.
No software installation is needed — upload images and compress them online. All files are transferred and stored through protected channels, and results can be downloaded immediately. Ideal for e-commerce product images, blog images and email attachments where size matters.
How much smaller can a compressed image be?

Image Compressor FAQ
Is this image compressor free?
Yes, completely free. All site tools share a daily quota of 20 uses, and each use (including re-compressing) counts once; uploads and downloads are not counted.
Which image formats can be compressed?
JPG, PNG and WebP. For GIF animations, use the dedicated GIF compressor.
Is there any risk of data leakage?
The image is uploaded so the server can compress it and offer a download. It is used only for that task, not sold, and not used to train models. See the privacy policy.
