I can confidently say that rearranging pages in a PDF for translations is totally doable, but it requires some technical know-how. Tools like Adobe Acrobat Pro or free alternatives like PDFescape allow you to extract, reorder, and insert pages with relative ease.
However, manga poses unique challenges—double-page spreads, right-to-left reading order, and preserving original artwork quality. I’d recommend using dedicated software like 'ComicTagger' or 'Krita' for cleaner edits, especially if you’re dealing with scanlations. Always keep backups of the original file, as PDFs can get corrupted during heavy editing. For bilingual releases, consider creating separate layers or side-by-side comparisons instead of altering the original layout, which fans often appreciate for authenticity.
