Source files are the editable versions of your work and the most important to save. They let you make changes, updates, or reuse designs in the future.
Different designers choose their primary tool based on their specialty. UI/UX designers have largely moved to Figma for its collaborative features and powerful prototyping tools. Brand designers often split between Figma and Illustrator—Figma for its quick iteration and presentation capabilities, Illustrator for its precise vector control and print reliability. Digital illustrators typically make Photoshop their home base for its robust brushes and layer effects, while vector illustrators prefer Illustrator’s precision and scalability. Print designers and publishers rely on InDesign for its superior typography and multi-page handling. While not a tool favored in most design studios, PowerPoint remains common in settings where presentations are the priority.
