What to expect from an ideal product

  1. LensUp compresses PDF files directly in your browser, no upload, no server, no waiting for a confirmation email that never comes.
  2. Your compressed PDF stays on your device the entire time, which matters when the file contains contracts, medical records, or anything you would not email to a stranger.
  3. No account, no trial, no paywall. Open the page, drop your PDF, compress it, done.
  4. LensUp works on any modern browser, so you can shrink a PDF on a work laptop, a personal Mac, or a Chromebook without installing anything.
  5. If you need to compress a scanned document that is already too large to send by email, LensUp handles that too, since it also covers scan to PDF and merge in the same free toolset.
