Technical note

How CZI and PDF differ in practice

PDF is a page format, so each CZI 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.

Our law firm deals with hundreds of scanned documents daily. reaConverter's OCR feature turns them into searchable PDFs, and the batch conversion saves us days of manual work. The output is flawless – even with old, low-quality scans. This is the best investment we've made for our document management.

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.
