Compression mode

Keep originals already under target

Images and ZIP are processed entirely on your device. Nothing is uploaded. JPEG output flattens transparent pixels to white.

How batch compression works

Select JPG, PNG or WebP images, choose 20 KB, 50 KB, 100 KB or 200 KB, and press Compress all images. Review the size of each output, download files individually or prepare a ZIP archive.

Fast or High Quality?

Fast uses your browser's JPEG encoder. High Quality uses MozJPEG and can retain more detail at small file sizes, but takes longer. JPEG output flattens transparency to white. Images already under the target can be preserved unchanged.

Privacy and limits

Processing happens entirely in your browser. For device performance, each batch is limited to 12 images, up to 25 MB each and 100 MB total. Very small targets may require smaller image dimensions.
