Drop your EPUB here
Anywhere on this page works
Make EPUB files smaller without changing their format. Drop one on the card above, choose how much smaller it should get, and download the lighter EPUB straight away.
There is nothing to install and no account to create, and the upload is deleted once your download finishes.
Drop the file in, or pull it from Drive, Dropbox, OneDrive or a URL.
Pick a quality target. The settings panel under the card gives you finer control if you want it.
Download the smaller EPUB straight away. Nothing is watermarked and no account is needed.
