Lite PDF tools turns animations off and points you at Compress, Merge, Images to PDF, ID photo resize, and Safe to share. It turns itself on when the browser reports save-data, a 2G or 3G connection, or about two gigabytes of memory, and you can open this page directly. The initial script for the whole app is already small. Lite does not fetch a model. Thumbnails stay on the ordinary path. A better connection later does not change the privacy rule: files are still processed here. Use Settings to leave lite mode. The page is the same origin as the rest of the site.

Lite PDF tools stays on this device. The download is the copy you keep, and Weesize does not store a second one. Close the tab when you are finished and the bytes are gone.

• No upload: lite mode only changes what this page loads and animates, not where the file goes.
• Speed: the file does not travel to a server and back, so the wait is only the work itself.
• Quality: the original is kept when the new file would be worse or is not actually smaller.
