                                FILE FORMATS

                      A file format is the way digital files are stored and organised so that a computer can read and
                      display them correctly. Each format has a specific structure that determines how data is saved,
                      compressed and used. Choosing the right file format is essential for maintaining the quality and
                      usability of your illustrations. Some of the common vector and raster file formats are as follows:

                      TYPES OF RASTER FILE FORMATS
                      Raster images are used for photographs, digital paintings and web graphics. The most common
                      raster file formats include:

                         ∑ JPEG (Joint Photographic Experts Group): A widely used format for photographs and web
                        images. It supports high compression but loses quality when saved multiple times.

                         ∑ GIF (Graphics Interchange Format): Supports animations and transparency but has limited
                        colour depth, making it less suitable for high-quality images.

                         ∑ PNG (Portable Network Graphics): Supports transparency and lossless compression, making
                        it ideal for web images and designs requiring a clear background.

                      TYPES OF VECTOR FILE FORMATS

                      Vector file formats store image data in mathematical equations, ensuring they remain crisp and
                      clear at any size. Common vector file formats include:

                         ∑ EPS (Encapsulated PostScript): A standard format for vector illustrations that supports high-
                        quality printing and scalability.
                         ∑ AI (Adobe Illustrator): A proprietary format used by Adobe Illustrator, allowing for advanced

                        editing and layering.
                         ∑ PDF (Portable Document Format): Though commonly used for documents, PDFs can also store
                        vector illustrations, making them useful for sharing and printing high-quality graphics.
