Why carry rolls of oversize paper and piles of binders when you can view everything on your iPad or iPhone? Large Viewer features include:

• Instant open
• Effortless scrolling
• Crisp detail even when zooming
• True color rendering
• Access and share via Mail, iTunes and Dropbox
• Accelerated PDF viewer

Large Viewer can read almost every image file format imaginable: AVS, BMP, CUR, DIB, FITS, GIF, ICON, JNG, JP2, JPEC, JPEG, JPEG2000, JPG, MAT, MIFF, MTV, MVG, PBM, PCX, PGM, PICT, PIX, PNG, PNG8, PNG24, PNG32, PNM, PPM, RLE, SGI, TGA, TIFF, TIF, TIM, VIFF, WBMP, WPG, SBM, XPM. ISO AO, USA Arch E, Large E or the standard D1 format files plus Apple quick look support for Office 97+, PAGES, RTF, iWorks, TXT, and CSV.


View large pages such as Engineering, Architectural or CAD drawings, in ISO A0 (841 × 1,189 mm/33.1 × 46.8 in), the USA Arch E (762 × 1,067 mm/30 × 42 in) and the Large E size (915 × 1,220 mm/36 × 48 in). Plus the more standard size of D1 (24x36 in).



Another big advantage is cost. For large building projects, blueprint charges can easily run from $15,000 to $20,000. Large Viewer can replace hundreds of pages of construction blueprints that can be routinely updated and shared with the push of a button.

What’s more, Large Viewer is the only app that can read Flexible Image Transport System (FITS) files, which are used to store, transmit, and manipulate scientific data and other images. FITS is endorsed by NASA and the International Astronomical Union.

Here’s what satisfied users around the world are saying about Large Viewer:

"Finally! This is the viewer that handles any size image I throw at it. Even ones with many dozens of megapixels! I have been looking for something like this. Others I have tried are extremely slow at scrolling or zooming, or can't handle the large images I want to view. But Large Viewer is screaming fast and can handle ever size image I have tried."



"Large Viewer is the best large image viewer I have seen, by far. And now with the new iPad with retina display it's even more useful! Simply stunning! If you want to view pretty much any resolution image and really show off what the retina display can do, you've got to get this app! Butter smooth scrolling, and just refuses to crash even when throwing 80-megapixel Phase One IQ180 images at it!”



"I am a professional civil engineer. I now have all my drawings loaded to my iPad when I go for inspections. It works well for large files and it is FAST."



"Incredible. Test passed with a TIFF file from 11.000 x 5700, weight 190 MB. Fantastic. It has a button to zoom to 100%, and it’s easy to go beyond the resolution of the file. Thanks and congratulations for the work. App absolutely recommended.”
