First, it’s crucial to ensure that your images are of good quality initially.

Bitmap images, such as JPG/JPEG and PNG files, possess a fixed number of pixels, so they may become blurry or pixelated when scaled.

Vector images, in contrast, maintain quality even when scaled. You can zoom in and out, and they keep looking fine. An example of this is the Scalable Vector Graphic (SVG) format. LaTeX does not natively support it. However, SVG images can be converted to Portable Document Format (PDF) and PostScript (PS), which are also vector formats, though they can contain bitmap images.

SVG images can also be converted to TiKZ images. We will speak about TikZ in Chapter 6, Creating Graphics. In any case, opting for vector formats over bitmap formats is advisable.

Today, the pdfLaTeX compiler is the most widely used. It allows the direct inclusion of PDF images. Furthermore, it supports the mentioned bitmap formats, JPG/JPEG and PNG...
