# Image specifications

> Recommended sizes, formats, and safe-zone guidance for every image you can upload to your event.

<Info>
  The platform uses a single image for both mobile and desktop. The image is
  cropped depending on the viewer's screen size — keep key content (text, logos,
  faces) centered and well clear of the edges.
</Info>

Before uploading images for your event, share these specifications with whoever is producing the assets. Getting the dimensions and safe zones right avoids cropping surprises and display issues across devices.

## File requirements

These limits apply to all images on the platform, unless a specific section below notes otherwise.

| Setting          | Value                           |
| ---------------- | ------------------------------- |
| Max file size    | 3 MB (2 MB for Campaign Emails) |
| Accepted formats | JPEG, PNG, WebP, GIF            |

## Event hero image

The hero image appears at the top of your event's public page and in booking confirmation emails.

| Setting          | Value          |
| ---------------- | -------------- |
| Recommended size | 1500 × 1000 px |
| Aspect ratio     | 3:2            |

The image is cropped differently across screen sizes. Keep your key subjects and any text centered — anything near the edges may be cut off on some devices.

## Event logo

The event logo appears on your event page alongside the event name.

| Setting          | Value        |
| ---------------- | ------------ |
| Recommended size | 250 × 250 px |
| Aspect ratio     | 1:1 (square) |

## Organizer logo

Your organization's logo is configured during account setup and appears on event pages and throughout the registration flow.

| Setting          | Value        |
| ---------------- | ------------ |
| Recommended size | 200 × 200 px |
| Aspect ratio     | 1:1 (square) |

The platform validates the aspect ratio on upload. Images that are significantly off-square may appear letterboxed.

## Bundle image

The bundle image appears on upsell cards shown to participants during checkout.

| Setting                    | Value                 |
| -------------------------- | --------------------- |
| Recommended size           | 1400 × 785 px         |
| Safe zone (always visible) | Central 1400 × 415 px |

One image is used across mobile and desktop. Content outside the central 1400 × 415 px area may be cropped on smaller screens. Keep all text, logos, and key visuals within that central strip.

## Add-on product image

Add-on (merch) product photos appear as thumbnails on the Add-ons step in checkout, and in a larger view when a participant opens a product for more detail.

| Setting          | Value                  |
| ---------------- | ---------------------- |
| Recommended size | 500 × 500 px (minimum) |
| Aspect ratio     | Square (1:1)           |

The thumbnail list crops to a wider box, while the full-size product view crops to a square — keep your subject and any text centered with margin on all sides so nothing important is cut off in either view. The platform automatically compresses and optimizes the image for web display, so you don't need to resize or convert the file yourself before uploading.

## Campaign emails

Images used in the **Advanced Email Builder** for marketing campaigns have their own size guidance and a lower file-size limit.

<Warning>
  Around 70% of emails are opened on mobile. Stack images vertically rather than
  side by side, and avoid placing important text inside images — use live text
  wherever possible so it stays readable at any size.
</Warning>

| Element                | Recommended width               | Notes                                                                                            |
| ---------------------- | ------------------------------- | ------------------------------------------------------------------------------------------------ |
| Header image           | 600 px wide                     | Keep height proportional — a banner 150–250 px tall works well for most headers.                 |
| Footer image           | 600–680 px wide, 50–100 px tall | Enough space for a logo and legal info without dominating the email.                             |
| General content images | 600 px wide                     | For multi-column layouts, divide accordingly — for example, 300 px per column in a 2-col layout. |
| Max file size          | 2 MB                            | Larger files increase load time and may affect deliverability.                                   |
| Accepted formats       | JPEG, PNG, GIF                  |                                                                                                  |

## Tips for getting images right

* **Keep text and logos away from the edges.** Images crop differently on different screen sizes — anything important should sit well inside the center.
* **Use PNG for graphics that contain text or logos** (sharper edges at any size). Use JPEG for photographs.
* **Compress before uploading.** Export at 72 dpi for web use and compress the file to stay under the size limit.
* **Check the aspect ratio before uploading.** An off-ratio image will trigger a warning in the dashboard and may appear letterboxed.
* **In emails, prefer live text over text in images.** Baked-in text can be too small to read on mobile and is not picked up by screen readers or spam filters.
