Fast Image Viewer


View TIFF, JPEG, PNG, FAXes and more. Includes advanced features like slideshow, show on map, rotate, crop, resize, save-as, set-as-wallpaper, share, export to PDF and more.

FIV is the only image viewer for Android that can easily open huge images such as GIS and Well Log scans. FIV includes unique technology for working with bitonal images that not only allows it to work with huge images, but accelerates the decompression and viewing. It also includes advanced "scale-to-gray" technology which is so fast that it doesn't delay the repainting when the scale is changed.

Documentation available here: FIV Help

FIV supports the following file types:

TIFF - single or multiple pages (uncompressed, Packbits, LZW, JPEG (type 6 & 7), Modified Huffman, G31D, G32D, G4, Flate (ZIP), stripped, tiled, planar, chunky, all bit depths)
BMP (Windows, OS/2, RLE)
DICOM (uncompressed, RLE, JPEG lossless, animated)
CALS type 1
JEDMICS C4 (US Military images)
GIF (animates in viewer and file browser)
FLI/FLC (animates in viewer and file browser)
PNG (all bit depths and options)
JPEG (baseline, progressive, lossless)
Targa (uncompressed, RLE)
FAX Files: QuickLinks, Microsoft (AWD), WinFAX, BitFAX
PDF - Note: PDF support is limited to scanned images such as FAXes, not text or vector graphics. This is useful because FIV can view these images faster than any other viewers.

Fast Image Viewer is built using our own imaging technology. The code is written in portable C and is OS and CPU independent. The documentation is available here: PIL.DOC
