A Guide to Shadow and Border Effects for Cutout Images

A background-removed subject placed directly onto a new background can sometimes look flat or "pasted on" — shadow and border effects are the fastest way to fix that and make the composite feel intentional.

A soft drop shadow, offset slightly down and to one side, mimics how light naturally falls on an object sitting on a surface — even a subtle shadow adds enough depth cues to make the image read as a coherent photo rather than two layers stacked together.

Borders serve a different purpose: a clean outline (white, black, or a brand color) around a cutout is a common style for stickers, badges, and social graphics, and can also help a subject stand out against a busy or similarly-colored background.

PixelloAI's Style panel exposes both effects with adjustable blur, offset, color, and width, so you can dial in anything from a barely-there realistic shadow to a bold, stylized border depending on what the final use case calls for.

When should you add a shadow?

When a cutout needs to feel grounded. A soft, low-opacity shadow under a product tells the eye the object sits on a surface; a hard, dark shadow looks pasted on.

When is a border useful?

To separate a subject from a similar-coloured background, to frame a screenshot, or to create a sticker look. Keep borders thin and consistent across a set.

Frequently asked questions

How strong should a shadow be?

Subtle: low opacity, soft blur, offset in the direction opposite your light source.

Can I add a white outline for stickers?

Yes, a border around a cutout gives the sticker effect.

Do shadows survive PNG export?

Yes if exported as part of the image; for transparent export, keep shadow on its own layer if you need it separate.
