About this tool

After the app has loaded, merge with the network off. Pages are copied in this process. Two files you already saved are enough for the test. No project account holds the packet.

Merge PDF offline 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: the privacy claim is that no upload request exists for the file.
  • 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.
