How to Make a PNG Sticker (Border, Shadow & Glow Effects)

• Transparent background. The foundation. Without transparency, the sticker has a box around it that looks wrong on any background that isn't white.
• White or colored border. The outline that separates the subject from the background. White works universally; colored borders work well for brand stickers.
• Enough padding. Space between the image edge and the border. Prevents the border from clipping into fine details.
• Shadow for depth. A subtle drop shadow makes the sticker feel three-dimensional and pop off the background.

If your image has a background, remove it first. Use PNGmaker's background remover at /remove-background — the AI detects the subject and removes everything else in seconds. Download the result as a transparent PNG before opening the Sticker Maker. If your PNG already has a transparent background, you can skip this step.

Border width is set as a percentage of the image width, so it scales correctly regardless of image size. The preview updates live as you adjust the slider.

• 4–8% is the sweet spot for most stickers. Visible on both light and dark backgrounds without looking chunky.
• 2–3% for subtle, minimal borders on clean illustrations.
• 10%+ for bold, cartoon-style stickers with a thick comic-book outline.

White is the universal choice — it stays visible on any background, dark or light, and it is the standard for Telegram and WhatsApp stickers. Use a colored border when the sticker is part of a branded set (match your brand's primary color) or when you want a specific aesthetic like a black outline for comic-style art.

• Drop shadow. Appears behind and below the sticker shape. Adds realistic depth — looks like the sticker is slightly lifted off the background. Most stickers benefit from a subtle drop shadow.
• Inner shadow. Appears inside the sticker shape, adding dimension within the subject. Gives a slightly embossed or inset look. Less common, but effective for certain illustration styles.

The glow effect adds a soft colored halo around the sticker — similar to a drop shadow but using a saturated color instead of a dark tone. Works best for neon, cyberpunk, and vibrant illustration styles. Combine a cyan or magenta glow with a dark background for an electric, eye-catching look.

Padding adds space between the image content and the border. This is important when the subject has detailed edges — hair, fur, thin outlines — that would otherwise get clipped by the border. A padding of 2–4% of the image width is usually enough. If you notice the border touching the subject's edges in the preview, increase padding until there is visible breathing room.

The result is always a PNG with transparency. The border, shadow, and glow are all composited onto a transparent canvas — so the sticker looks natural on any background.

• Telegram: resize to 512×512px after creating the sticker (use PNG Resizer).
• WhatsApp: upload the transparent PNG directly — WhatsApp handles sizing.
• Canva, Figma, iMessage: all accept transparent PNGs natively.
