How to what a browser pdf tool can and cannot do

  1. 1. Start from the tool page for the job, not from a slogan.
  2. 2. Read the one-line limit if the action is disabled.
  3. 3. Use a local desktop program for encryption, OCR, and true redaction.

A browser can merge, split, reorder, rotate, crop, stamp numbers, watermark, compress images, build a PDF from pictures, render pages to JPEG, and pull a text layer into a simple document. It can do those without a server. It cannot, in this version, encrypt, decrypt, truly redact, OCR a scan, rebuild a spreadsheet, reconstruct slides, fill AcroForm fields, or apply a certificate. Those screens say so. A tool that shows a finished download for a job it cannot check is worse than a tool that refuses. Use a named desktop program on your computer for the refused jobs, still without uploading, if you need them today.

What a browser PDF tool can and cannot do 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.
