Uploading images is a great way to personalize your campaign and make it more visually interesting for your buyers or donors.
Generally speaking, your image can be of any size. However, if the image doesn't respect the ratio of the frame it has to be uploaded into, it may not be displayed as you intended. To ensure your images look their best and to optimize the user experience for everyone, here are some guidelines to follow when uploading images.
1. Image Ratios
Banners
Zeffy uses square banner images (a 1:1 aspect ratio). This ratio ensures that your images fit nicely on most screens, and look great on mobile. If you don't have a square image, don't worry - it's not a strict requirement. That just means that some content will not fit inside the square frame.
Logos
Logo images should also respect the 1:1 aspect ratio. That means, if your image is 500 pixels wide, it should also be 500 pixels in height.
If you have a portrait or landscape image, we recommend using free tools like Canva to adjust your logo. Oftentimes, the fix is as easy as placing your logo on a white square and then exporting that image to upload it onto Zeffy.
You can use other tools like Canva and ChatGPT to format your images to fit our dimension requirements if needed. Here is a tutorial on how to use these tools to format your images: Watch now
2. Image File Size
Smaller image files load faster and consume less bandwidth, which benefits both you and other users. We recommend keeping your image files below 10 megabytes (MB). This size limit allows for quick and seamless image loading without compromising quality.
3. Image Resolution
While we don't have strict resolution requirements, we suggest keeping your images under 1200 pixels in width. Images wider than this can sometimes cause issues with display. You can always resize your images using various image editing tools or software to ensure they meet this guideline.
4. Cropping your image
Once your image is uploaded, it will automatically be cropped to a square. If you would like to adjust the crop, you can hover over the image and drag to reposition.
5. Supported Image formats
The following file formats are supported for image uploads in Zeffy
- JPEG (or JPG)
- PNG
We recommend using JPEG for photographs and images with lots of colors, and PNG for images with transparency or sharp lines. The choice of format depends on the content and your specific needs.
