DownloadHow to Compress an Image
Choose an image, select the output format and quality, then select Compress Image.
Quality, format, and file size
Lower JPEG or WebP quality usually reduces size by discarding more image detail. PNG is better for sharp graphics and transparency but may be larger for photographs; WebP often gives a useful balance for web delivery.
What re-encoding can change
Compression keeps the selected pixel dimensions but re-encodes the image. Fine texture can soften, color values can shift slightly, and metadata such as camera details may not be carried into the downloaded result. Compare at the intended display size before publishing.
Frequently Asked Questions
Where does image compression run?
No. Image compression runs with Canvas in your browser. Your file is not sent to or stored on a server.
Can I compress PNG images?
Yes. PNG images can be re-encoded as JPEG or WebP to reduce file size. Choose WebP to preserve transparency.
