## What is CAJ to PDF?

A CAJ paper arrives on your phone or iPad, and your computer is nowhere near. 
  "I'll convert it when I'm back at my desk" usually means it never gets        
  converted.                                                            
                                                                                
  This app puts that step in your hands: pick the file, and it takes care of the
   rest.                                                                        
   
  【What it does】                                                              
  · Converts CAJ / KDH / NH files to PDF                    
  · Select several files at once — they convert one by one in the background,   
  with visible progress                                                         
  · Export or share the results, or save them to Files                          
                                                                                
  【Why convert on your phone】                                                 
  · Everything happens on your device — files are never uploaded and never pass 
  through any server, so unpublished manuscripts and confidential material are  
  safe to handle                                            
  · No internet required; it works on a plane, or in a lab with no connection   
  · Universal across iPhone and iPad; the two-column layout gives you more room 
  in iPad landscape                                                             
                                                                                
  · Supports common CAJ files; results depend on the structure and quality of   
  the source file itself                                    
  · For pages that are pure scanned images, the app performs no text recognition
   (OCR) — those pages stay as images                                           
  · Some files with unusual encodings contain no finished page layout, so the
  positions of text and images are inferred by the app and may differ from the  
  original. When it encounters such a file, the app tells you so honestly before
   converting                                                                   
                                                            
  【Pricing】
  · Converts 5 files per day for free
  · Need more? A subscription unlocks unlimited conversions — weekly, monthly,
  or yearly                                                                     
  · Subscriptions are billed through your Apple ID and can be cancelled anytime
  in your App Store account settings                                            
                                                            
  【Before you use it】                                                         
  Please only process files you have lawfully obtained and have the right to
  convert, and use them for lawful purposes such as personal study, research, or
   backup. This app performs only public, reversible format conversion; it does
  not remove protection from any password- or permission-protected file.
