This application is a helper app for our iPhone/iPad LargeViewer application which allows you to view 100 mega-pixel TIFF/JPEG/JPEG2000 images, or PDF pages from normal page sizes to over 30x36 inches. It gives you super fast PDF, JPEG, or TIFF file viewing on your iOS device, and enables you to read PDF files that are normally unreadable by most popular PDF readers. Our IOS apps give you instant scrolling for page sizes measured by meters or by the yard, unlike any other reader in the App Store.

This application allows you to take a PDF, JPEG, JPEG2000, or TIFF file or a FOLDER of files and subfolders, and process it for our iOS products.

This is app is especially helpful when dealing with 8,000 page PDF text books, or TIFF based Well Logs that are 11.5 inches by 85 feet, or Panoramic photos that span 250 mega-pixels.

Now supports downscaling for scanned 2400 dpi TIFF documents to make smaller 300 dpi images, 32 bit color, and choices for the compression factor.

That said we also make viewing and scrolling your normal PDF based book extraordinarily fast.

What’s New

Version 6.9

Reduce memory needs in order to work better on machines with only 4GB of Ram.
