TIFF not suited for long-term preservation
e-archiving and universal accessibility

The Enterprise Content Management (ECM) industry
has been standardized on TIFF-encoded images
for over 25 years.

Billions of page images,
most of them scanned from paper,
populate hundreds of thousands of
document management system
installations worldwide.

Images that are unaccessible when
the ECM vendor is not there any longer.

TIFF is proprietary (Adobe owns it).
Pages in TIFF are just pixels.
Images cannot substitute for documents.

Government regulations will require that text,
semantics and navigation, annotations, form-fields,
digital signatures, and so on, be available to all users.

TIFF images can't be made accessible
to users with disabilities,
but PDF documents can
(see the ISO Standard PDF/UA).

In the future the ECM/EDRM industry
will be forced to abandon TIFF, and
accessibility is one of the key reasons why.

TIFF images are a non-starter in terms of accessibility.
