FAQ

Which format should I use in a paper?

Use SVG when the journal or document workflow accepts vector images. Otherwise choose a single- or double-column preset and export a high-resolution PNG.

Does the academic preset guarantee journal compliance?

No. It provides monochrome styling and practical dimensions, but you must still check the target journal's figure requirements.

When should I choose vector SVG over high-resolution PNG export?

Vector SVG offers infinite scalability and small file sizes for web docs, while high-DPI PNG guarantees universal compatibility in Word and slide decks.
