The bitmap image file format or bmp file for short, is a raster graphics image file. It uses a dot matrix data structure to represent pixelated points of color and to store digital image information. The format optionally supports compression and has wide cross platform support on all the major computer operating systems. Because bmp files are raster graphics files, image resolution is constrained meaning images in this format will not scale without loss in quality. This is in contrast to vector graphics images that can scale to arbitrary resolutions.
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 BMP to GIF conversions, preserving clarity while trimming file size. Finished audio streams instantly across phones, tablets, desktops, and modern browsers without extra tweaks.
Upload BMP 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.
Because bmp files can be uncompressed, it is capable of supporting larger file sizes and thus higher resolution and higher quality images. This capability makes bmp files inappropriate for digital distribution via webpages or through bandwidth limited networks. Pixels in a bitmap support deferent color depths from 1 bit of either black or white, to grayscale which is 8 bits, to finally 24 bit RGB giving a possible 16777216 possible colors. Color depth can go as high as 32 bits however this is rarely encountered or needed in practice.
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.
