Q - question

Which raster format to choose for transferring images?

A - answer If you need to send an output of a CAD application, rendering, photo, map or another picture over e-mail, or to otherwise transfer it electronically, and you cannot use a vector format, it is important which of the many raster formats you choose. You can significantly influence the file size and quality of the image. Each file format has its advantages, disadvantages and recommended usage.

FormatAdvantagesDisadvantages
BMPAlmost none, maybe: general availability on the Windows platformsvery inappropriate format, do not use; format is not compressed - resulting file is unnecessarily large
GIFEfficient, compressed lossless format, suitable for transferring screen captures, CAD data, maps, schematics, logos, etc.; transparency option8-bit color depth, limited palette of 256 colors - do not use for renderings and photos
JPGVery efficient, well compressed lossy truecolor format, well suited for transferring photographs and pictures where a loss of some pixels is not importantlossy compression, makes artefacts in the picture, blurs edges - do not use for CAD data
PNGCombines the advantages of GIF and JPG, compressed truecolor format, well suited for transferring accurate images, including CAD data, features alpha-channel (transparency)not so efficient format in terms of the file size
TIFCompressible format for professional use - maps, scanned drawings, suitable for CAD and GIS data (monochrome and color)too many variants and sub-types, not all of them fully supported; not so widespread

All of these formats can be exported and imported from/to AutoCAD, most of them are supported also in Revit and Inventor.
