Choosing the right image outline
A thin contrasting outline helps an object remain visible on mixed backgrounds. A thicker white or brand-colored outline creates the familiar sticker effect used in thumbnails, social graphics, product callouts, and messaging assets.
Object tracing depends on transparency. If the source has an opaque background, use the full image frame mode or remove the background before adding the outline.
Frequently asked questions
How do I add an outline around a transparent PNG?
Upload the PNG, choose Trace transparent object, then set the outline width and color.
Can I outline a JPG image?
Yes. Use the full image frame mode because JPG files do not support transparent object edges.
Can I choose a custom outline color?
Yes. Use the color picker to select any outline color.
Does the output preserve transparency?
PNG output preserves transparency outside the outlined object.
