3-Heights™ TIFF Toolbox - process and convert your TIFF files

The 3-Heights™ TIFF Toolbox API enables to process and convert TIFF files. Examples of such processing functions are the merging and splitting of multi-page files, the conversion of other raster image formats such as JPEG into TIFF and the conversion of TIFF files into PDF/A.

The optional OCR add-in makes output files searchable in full textmode.PDF/A has been acknowledged world-wide as the ISO standard for long-term archiving since 2005. The TIFF to PDF/A converter is used to convert images into a standardized format, for instance for electronic archiving or elec-tronic data exchange.

The 3-Heights™ TIFF Toolbox API is characterized by a robust design, high throughput, ability to process large files and accurate image reproduction.

Notice: The 3-Heights™ TIFF Toolbox is not an own product but part of our 3-Heights™ Image to PDF Converter.

Areas of use - TIFF processing

TIFF archive migration

TIFF was specifically developed for storing image data, and is mostly used when dealing with scanned documents. This also includes numerous proprietary TIFF extensions that were developed for specific application areas such as geodata or text recognition.

With the TIFF Toolbox, existing TIFF archives can be efficiently migrated into long-term PDF/A-compliant archives without losing any information. The conversion to the PDF/A format allows you to achieve standardized archiving in a unified format that offers a high compression rate, text recognition, embedded metadata and digital signing.

The PDF formats store structured objects and are therefore more compact than the TIFF raster format. This saves storage space and enables more efficient data exchange (FTP, email attachments, downloads).

Scanning workflow; paper and facsimile capture

The electronic archiving of paper documents and faxes, as well as electronically produced files from specialist applications, often generates TIFF and JPEG files. 

The loss-free conversion of TIFF files into the long-term archiving format PDF/A creates a unified format. Alongside this standardization, you also gain a wide range of options and additional features for further processing in the documentation process.
