About this tool

WhatsApp supports documents up to 100 MB, but large PDFs consume significant mobile data and take longer to transmit over cellular connections. Shrinking your PDF to 1 MB or 2 MB makes sharing fast and light for recipients. Our browser tool processes the file on your smartphone without server uploads.

WhatsApp PDF size limit 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: shrinking files on mobile saves cellular data.
  • 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.
