First released in 1998, the Djvu file format is an alternative open file format for scanned document storage. It is specifically targeted at documents that possess text, vector graphic drawings, photos, and colored images. The format's main selling point is its high quality authoring with minimum storage space making it popular in the distribution of magazines, comics, and ebooks. This fact places it in direct competition with the pdf format by Adobe Systems. The text layer in the Djvu file format supports optical character recognition which allows for text selection, copying, and pasting from .djvu files to other text processing applications. Free browser plugins are available for most major internet browsers which allows hosted .Djvu files to be opened directly through compatible browsers.
The TIFF format was developed by the company Aldus in 1986, which was later acquired by Adobe systems who now own the rights on the format specification. TIFF, which refers to the Tagged Image File Format, is a raster graphics file format popularly used in desktop publishing and print. Its initial development goal was to create an alternative and cross platform format that would replace the numerous proprietary formats used by scanners developed in the 80's. Later revisions, after Adobe took over the development of the format, saw the TIFF format become extensible to adapt with growing and changing needs of the graphics industry. TIFF supports high color depth and is well suited to OCR applications, scanning, image editing and authoring as well as word processing. The format uses the filename extension .tiff for files stored in the format.
FreeFileConvert uses tuned encoding for DJVU to TIFF conversions, preserving clarity while trimming file size. Finished audio streams instantly across phones, tablets, desktops, and modern browsers without extra tweaks.
Upload DJVU files from desktop, tablet, or cloud storage, queue multiple jobs, and let the converter finish autonomously. Return whenever convenient to download synchronized TIFF results on any device you rely on.
Process up to 5 files sized 1000 MB per batch without splitting queues manually. Mixed-format uploads convert together, producing consistent TIFF audio with dependable progress tracking.
The file format has a three pass compression technique in which single scanned images are divided into three separate images and compressed individually. The images are separated into background, foreground, and mask images. The Djvu file format then makes use of IW44, a wavelet based compression algorithm, to compress background and foreground images while the mask image is compressed using JB2 encoding.
The original version of the TIFF format had no support for compression but by the 5th release of the format, LZW compression (a lossless compression algorithm) was supported. However, the format can also be used to store data in a lossless format without compression. This cannot be done though if the TIFF file is acting as an archive for JPEG data which is inherently lossy. TIFF supports monochrome, grayscale, palette color, and full true color.
