How to resize an image to 728x90
- Choose or drop your images above.

- Download the resized files individually or as a ZIP.
About 728x90 pixels
A 728x90 image is landscape, with an aspect ratio of about 8.09 to 1, and holds 65,520 pixels in total. At 300 DPI it would print at about 2.4 x 0.3 inches (6.2 x 0.8 cm). As a JPEG it usually lands between 7.2KB and 14KB, depending on the picture and the quality you choose.
Where 728x90 is used
The standard leaderboard banner size from the IAB, placed at the top of many web pages.
- Put the important part in the centre. Apps crop banners differently on phones and desktops.
- Avoid small text near the edges, where profile pictures and buttons can cover it.
- Keep the file light. A banner of a few hundred KB loads fast and is rarely rejected.
Crop to fill or fit inside?
Crop to fill always gives exactly 728x90 by trimming the edges that do not match the shape. Fit inside keeps the whole picture and scales it so neither side exceeds 728x90, which can leave one side shorter. For a typical 4:3 phone photo, crop to fill removes about 84% of the picture. A 3:2 camera photo loses about 81%, a 16:9 screenshot about 78%, and a square image about 88%.
Quality and format
Check the result before you upload
Open the finished file and check three things: the picture measures 728x90, the subject is not cut off, and the file is small enough for where you upload it. If a platform sets a size limit, run the result through the online compression tool or choose a limit such as 200KB.
A tip for this size
Banner ads have file size limits, so compress the finished image. Need another size? Try 1584x396, 820x312, 1500x500, the general image resizer, or browse every size preset.
Frequently asked questions
Why is my image not exactly 728x90?
You are probably using Fit inside, which never crops. Switch to Crop to fill for exact dimensions.
How big will a 728x90 file be?
As a JPEG, usually between 7.2KB and 14KB. Photos with lots of fine detail come out larger, and simple graphics smaller. Lower the quality for a smaller file.
Is 728x90 the right size for leaderboard banner ads?
It is a widely used size for leaderboard banner ads, but platforms and agencies change their rules. Check the current guidelines before you upload.
Will detail survive at 728x90?
At small sizes fine detail disappears. Crop in close on the main subject and use a simple, high-contrast picture for the best result.
