About PDF to CBZ
CBZ is the standard format for digital comics and is simply a ZIP archive of page images in reading order. Comic readers on phones, tablets and e-readers open it natively and handle page turns, double page spreads and reading direction properly, which generic PDF viewers do not.
Converting a PDF to CBZ renders each page to an image and packs them in order. It is the right move for scanned comics, manga, graphic novels and art books that arrived as PDFs but are being read on a device with a proper comic reader.
You control page resolution and image format. JPG keeps the archive small, which matters on a device holding a large library. PNG is lossless and better for line art and screentones, where JPG artefacts are visible against flat areas.
Rendering happens locally, so a large scanned volume is not uploaded anywhere. Conversion time scales with page count and resolution, and a couple of hundred pages at reading resolution is comfortable on an ordinary machine.

Frequently asked questions
Why convert a PDF to CBZ at all?
Comic readers handle CBZ better than PDF: proper page turns, spread detection, right to left reading for manga, and much faster navigation in long volumes.
What resolution should I use?
Around one hundred and fifty DPI is comfortable on a tablet. Three hundred is worth it only for detailed art or large screens, and roughly quadruples the archive size.
JPG or PNG inside the archive?
JPG for scanned or painted artwork. PNG for line art, screentones and flat colour, where JPG compression shows as haze around the lines.
Will the text be searchable?
No. CBZ holds images, so there is no text layer by design. If searching matters, keep the PDF and run OCR PDF on it instead.
