"The fastest converter I've used."

I get briefs in PDF every week. This is the only converter that keeps my table headers in the right column. Saves me 20 minutes of reformatting per file.

"Saved me a stack of contracts."

I had 30 vendor PDFs to update with our new VAT. Converted them all in 10 minutes, did a find-and-replace, re-exported. Used to take 3 hours.

"Even kept the fonts."

I converted a portfolio PDF. The fonts, the column layout, even the page numbers came through. I just opened it in Pages on my iPad and edited.
