Correct text in a scanned PDF, and prove nothing else moved

CECO PDF corrects wrong text in your own PDFs, then checks its own work. Nothing else on the page changes in the file you download.

What it does

• Corrects a word on a scanned page, not only on a page that carries selectable text.
• Checks every correction against the page before the file can be downloaded, and says what it found.
• Refuses a correction that fails its checks, and shows the measurement that refused it.
• Keeps a record of every change inside the corrected file: the page, the region, what it said before and what it says now.
• Finds a phrase across a whole document and walks through the places it occurs, asking about each one.
• Shows before and after at magnification, unsmoothed, so a one-pixel mark survives to be seen.
