A TIFF image viewer for Windows web browsers
AlternaTIFF is a web browser add-on (ActiveX control or plug-in) that
displays most of the
common types of TIFF (.tif) image files. It works in most
web browsers for Windows XP and higher (Vista, Windows 7, Windows 8 in
desktop mode, etc.).
Current version: 2.0.8 - 2015-05-22
AlternaTIFF is free to use for any purpose; however, you will
be required to register it before it can be used to view images.
You will be told how to register when you install it, or when you first
use it to view an image.
(You do not need to search this web site looking for a way to register.
If you are not asked to register, it means your computer has
already been registered.)
AlternaTIFF is available as either a
Netscape-style plug-in or
an ActiveX control for Internet Explorer.
Please choose from the following three options
(there are two download methods available for the ActiveX control).
If you use Internet Explorer, you should probably
select option 1. Otherwise, select option 3.
1. ActiveX control, auto-install
For Internet Explorer.
32-bit version: <Click here to go to the
installation page> - For 32-bit IE on any version of Windows.
64-bit x64 version: <Click here to go to the
installation page> - For 64-bit IE on 64-bit Windows.
If you're not sure, choose the 32-bit version.
Note: You must be logged in as a user who has (or can acquire) sufficient
privileges to install ActiveX controls on your computer.
2. ActiveX control, in a downloadable ZIP file
For advanced users of Internet Explorer.
32-bit version: alternatiff-ax-w32-2.0.8.zip
64-bit x64 version: alternatiff-ax-w64-2.0.8.zip
This version can be downloaded once and installed on multiple computers,
but it requires an unzip utility, and knowledge of how to
manipulate files and folders. It usually has to be installed from
an administrative command prompt.
3. Standard web browser plug-in
For Firefox, and other browsers that support plug-ins.
NOTICE: Firefox and Chrome have deprecated support for plugins like alternatiff so you may no longer be able to use it.
See Firefox support information for details.
