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.
A .cgm extension is used by CAD (Computer Aided Design) software for its computer graphics metafile format. The .cgm file extension format enables interchange of graphical data for the computer representation of 2D graphics that are independent of a specific device, platform, system or application. The CGM file format is a universally accepted format for text, raster graphics and 2D vector graphics. The CGM format files are widely used by aviation, engineering and other applications related to the technical field.
FreeFileConvert uses tuned encoding for BMP to CGM 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 CGM 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 CGM 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.
A .cgm extension file format is compatible with any operating system. These are vector graphics format files that can support three encoding methods. One of these methods is the clear text encoding that allows reading and modification of a file using a text editor.
Upload your image file in the BMP format from your device, Dropbox, or Google Drive.
Select CGM as the output format and click Convert. Adjust optional settings if needed.
Download the converted vector file. Each file stays available for up to 5 downloads.
