When you need to embed an image in a text-formatted file, such as an HTML or CSS file, inserting binary image data directly may result in incorrectly formatted files. To solve this problem, you can convert the image to Base64-encoded format and embed it as a data URI in a text file. This approach allows you to include the image data as a text string without destroying the file structure. It's worth noting that tools that convert images to Base64 typically support image files up to 50 MB in size. If you need to do the opposite, i.e. convert the Base64 encoding back to an image, you can look for a corresponding Base64 to image conversion tool.
