When exporting from Illustrator, which file type can include unused symbols?

When exporting from Illustrator, choosing EPS as the file type allows for the inclusion of unused symbols. EPS, or Encapsulated PostScript, is a vector format that can encapsulate a wide range of graphic data, including elements that are not currently used in the artboard, such as unused symbols. This feature is beneficial for maintaining the integrity of complete designs, enabling easier future edits or revisions by retaining all relevant assets in one file.

In contrast, other file formats such as PDF and JPEG do not support the inclusion of unused symbols in the same way. PDFs are more focused on static presentation and may not retain all design elements from the original document, especially those not in use. JPEG is primarily a raster format that does not preserve vector data or symbols, rendering it unsuitable for including unused graphic assets. SVG files typically prioritize web and interactive design elements but may not specifically incorporate unused symbols, targeting only what is actively used in the design.

Thus, EPS stands out for its capability to include any unused symbols, making it advantageous for designers looking to export comprehensive and editable files.
