Technical note

Before you convert KRO to PDF

PDF is a page format, so each KRO image is placed on a page rather than converted into something else. Two settings decide how the result looks: the DPI, which fixes how large the image sits on the page, and whether a batch becomes one file per image or a single merged document. reaConverter can do either.

PDF is certainly a universal format, but sometimes you need JPEG files instead. For conversion, I use reaConverter - a lightning-fast program. No online editor can match its speed. Install it once, and you're set. Just open, convert, and done!

I was skeptical about converting PDFs to editable formats, but reaConverter's PDF to Word conversion is surprisingly accurate. It preserves tables and formatting. For a one‑time job, I used the online version, but I'll definitely buy the desktop app for future work.
