Drop your image in below, compress, and attach the lighter version.

Will the photo still look good after compressing?+
Yes. At a sensible quality level the difference is invisible on screen, but the file is a fraction of the size.
Which image formats are supported?+
JPG, PNG, and WEBP. You can also convert between them if a different format compresses better for your image.
Can I compress several images at once?+
Yes. Add multiple files and download them together as a zip.
