Add transparent padding to an image

Grow the canvas around a logo without touching the artwork, so a circular crop has room to work. Nothing is uploaded — the image is decoded, padded and saved inside this page.

Add an image and the padded result appears here,
with the crop circle drawn over it.
Why a circle needs so much room. A square cropped to its inscribed circle loses every corner — the largest square that fits inside a circle is about 71% of its width. Padding measured from the image's diagonal is the amount that guarantees nothing is cut, which is what the button above works out.
How it works

How to add transparent padding to an image

  1. 01Add your image

    Drop in a logo or picture. Transparent edges can be trimmed first, so the centring is right.

  2. 02Choose the padding

    Set pixels for every side, or press Pad to survive a circle and the amount is worked out for you, with the crop drawn over the preview.

  3. 03Save it

    As PNG or WebP. Both keep the transparency.

Questions

Questions about Image Padding

How much padding does a circular crop need?

About 21% on each side of a square image. A circle cut from a square loses the corners, so the padding is measured from the image’s diagonal, which guarantees nothing is cut.

Why is my Discord server icon cut off?

Discord, like most apps, shows server icons and profile pictures as circles, which crops the corners off a square logo. Pad it to survive the circle and the whole logo stays visible.

Does padding change the logo itself?

No. The canvas grows around it; the artwork is never resized or redrawn.

Is my logo uploaded?

No. This page is served with a security policy that forbids it from making any network request, so the browser itself refuses to send your image anywhere. You can watch your browser's network tab stay empty, or switch your connection off and carry on.
