Image · Browser only
Compress images, privately.
Reduce JPG, PNG, and WebP file sizes with Canvas APIs in your browser. Choose a quality level, compare the result, and download each optimized image.
Your images never leave your device.
Your images never leave your device. Compression runs only in this browser tab.
How it works
Add, compress, download.
Drop or select multiple images, choose a compression level, then review the original and compressed previews before downloading one image or all completed images.
Privacy
Your images never leave your device. There is no upload endpoint, account, cloud storage, or server processing.
Formats
JPG files are optimized as JPG. PNG and WebP files are optimized as WebP, which can preserve transparency while using the browser's lossy compression controls.
Limits
Add up to 20 images, 25 MB each and 150 MB total, to keep memory use practical in a browser tab.
