About CBZ output
Comic reader apps such as CDisplayEx, YACReader, Panels and Chunky prefer CBZ to PDF. A CBZ is a ZIP of page images, plus a small information file with the title and page count.
When a page is just one scanned JPEG, the original image is copied as it is. Other pages are drawn as high-quality JPEGs.
Tip: Need ordinary images? PDF to JPG and PDF to PNG make smaller files.
Your files stay on your device
Most online PDF sites upload your documents to their servers. Aleynray Ai does the work inside your browser instead, on your own computer or phone.
Nothing is sent anywhere, so contracts, bank statements, IDs and medical forms stay private, and there is no waiting for uploads.
