Overview
When creating a Marketplace add-on, you can add an icon to serve as a visual identifier for your users. The icon appears in many places (e.g., the Marketplace website and users' dashboards), so it is important that your icon is easy to view in any size and follows certain rules. In this guide, we will walk through guidelines and best practices for uploading a great add-on icon.
Here is an example of an icon in context:
File Specifications
| Spec | Detail |
|---|---|
| File type | .png |
| Background | Transparent |
| Size | 24x24px Avoid going too much higher than 24x24px. In some cases the icon will be resized down to 16x16px which will make the icon unrecognizable if it's too large |
| Aspect ratio | 1:1 (square) |
| Resolution | 72 dpi |
| Corners | No round corners |
Colors
Foreground
We prefer dark colors with good contrast to be seen against a light background.
Background
A transparent background is the only accepted background.
Grid
Your icon should be designed to fill 10/12ths (20px for a 24px icon) of a vertical or horizontal space. Make sure to leave a margin of at least 1/12th (2px for a 24px icon) margin around your icon that is free of any visual elements.

DOs & DON'Ts
Contrast
| DON'T use low contrast foreground colors | DO use nice contrast colors. Transparent background is a plus! |
|---|---|
 |  |
Margins
| DON'T export the icon without any margins | DO give your icon some room to breath |
|---|---|
 |  |
Visual effects
| DON'T use drop shadows, bevel, emboss, or any other similar visual effects because those don't downscale well | DO use outline icons with proper line width. They look sharper while downscaling |
|---|---|
 |  |
Copy
| DON'T use excessive amounts of text in your icon. This makes it hard to identify and read at smaller sizes | DO use a mark that will visually represent your add-on |
|---|---|
 |  |
Ownership
| DON'T use a logo and a name you don't own | DO use a original mark and name |
|---|---|
