If you open your BioRender PDF export directly within your browser, you may notice some grey lines appear around images in your illustration.

Please note that this is only an issue with the Chrome and Adobe PDF viewer. We recommend opening the file from your device’s default PDF viewer, or an alternative such as Safari or Firefox viewer to see your illustration without the grey lines. Printed copies of your illustration will not show the grey lines.
