What happens to the document size when the photo file size increases?

The relationship between photo file size and document size is an important aspect to understand in digital photography. When the file size of a photo increases, it typically implies that the image has a higher resolution or contains more data, such as detailed information about colors, textures, and visual elements. Consequently, as the image file's size increases, the document containing it—often a digital file that incorporates this photo, like a PDF, Word document, or graphic design project—also grows in size to accommodate the larger image.

The most logical understanding is that both the photo file size and the document size would increase together, as the document must hold all the original image data without loss. Therefore, when a photo's file size increases, the document size necessarily becomes larger as well to encompass that increase. This direct relationship reflects the way digital files are structured and stored, as each component of the document must reflect the entirety of its content, including any embedded or linked images at their full size.
