Sticker Maker — free online tool
You found a nice cut-out image with a see-through background, but it still doesn't look like a real sticker. What's missing is that white border around the edge that every printed sticker has. We added a free tool that gives you exactly that — Sticker Maker — right in your browser.
What it does
You upload a PNG that already has a transparent background, then pick the color of the outline and how thick you want it. The tool draws that border around your image so it looks like a proper sticker, and lets you download the finished picture.
Nothing leaves your device
The whole thing runs inside your browser. Your image is never uploaded to a server and nothing is saved anywhere. When you close the tab, it's gone — your picture stays on your own computer the entire time.
How to use it
- Open Sticker Maker and upload your PNG with a transparent background.
- Choose the outline color and how thick the border should be.
- Download your sticker-ready image.
It's free with no limit. There are more small tools on the Apps page.
