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 .gif filename extension refers to the GIF graphical file format created by CompuServe in 1987. The format is from the class of raster graphics which uses a dot matrix type data structure of orthogonally placed pixels, each with their own color information. The file format has a rich history of usage in storing sprite data for video games especially those released in the early 90's. The GIF format has also been used in low-resolution animation clips distributed over the internet, and in design of sharp-edged art that utilize a palette of a few colors up to a max of 256 colors. The GIF file format has its advantage in its compression technique, which limits file size but does not compromise image quality. The file format natively opens on many of the popular web browsers.
FreeFileConvert uses tuned encoding for DJVU to GIF 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 GIF 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 GIF 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 GIF format is formally specified in the GIF89a Specification released in 1989 and maintained by the World Wide Web consortium. The format uses the Lempel-Ziv-Welch data compression algorithm to create a single lossless file of multiple images known as frames. The GIF file format has a structure of blocks composed of control, graphics rendering, and special purpose blocks. The blocks begin with the header block, followed by the logical screen descriptor block, the graphic control block with the actual image and or text, and finally the gif trailer marking the end of the file.
