In many situations, especially with large-scale document leaks such as bank scans, you may encounter a significant number of documents in TIFF format. These multi-page TIFF files are often used for scanned documents due to their high quality and support for multiple images within a single file. However, TIFF files are not widely supported by most software applications, making it challenging to view and process these documents. In contrast, PDF is a universally accepted format that is compatible with a wide range of programs and devices, making it a preferred choice for document management and recognition.
