Capture add-padding-to-PNG and PNG-safe-area intent with a browser-first utility that sits between trim, favicon prep, and sticker exports
Cleanor Labs
These sections explain the job in plain language and set expectations for what the tool should do well.
To add padding, upload one PNG and choose how much safe area you want around it. The generator keeps the artwork at its original size and expands the canvas, then centers the subject so it has even breathing room on every side.
You can keep the original aspect ratio or snap the output to a square canvas, and you can make the padding transparent by default or fill it with white, black, or a custom solid color. The export is a clean PNG ready for icons, stickers, or marketplace assets.
All canvas expansion and export happen locally in your browser, so the PNG stays on your device and nothing is uploaded to a server.
A resize tool changes the image dimensions by scaling the content, so the subject itself gets bigger or smaller. Padding is different because the artwork stays exactly the same size and only the canvas around it changes.
That makes padding the right choice when an app icon, sticker, or marketplace cutout already looks correct but needs more breathing room inside the file. Square mode is especially useful for icon and app-asset prep, where the canvas needs to be balanced even if the subject is not naturally square.
