The 336×280 format at a glance
The Large Rectangle at 336×280 pixels is a bit bigger than the Medium Rectangle, so it stands out more. It is served a lot within text content and gets good visibility.
What it's good for
- Eye-catching in-content ads with more image space
- Product or offer ads with a clear subject
- An alternative to 300×250 for more presence
Common mistakes
- Placing key messages too small and too close to the edge
- Upscaling an image made for 300×250 until it gets blurry
- A busy design without a clear focal point
How it works
- 1 Drag your image into the box or choose it: JPG, PNG, WebP and other common formats.
- 2 Move and resize the frame until the crop fits. The aspect ratio 6:5 is fixed, and “Auto-center” finds the subject on its own.
- 3 Choose the file format (JPG, PNG or WebP) and the quality if needed.
- 4 Download the image at exactly 336×280 pixels, ready to upload.
Frequently asked questions
What size is the Large Rectangle ad banner?
The recommended size is 336×280 pixels with an aspect ratio of 6:5. Your image is downloaded at exactly this size.
Will my image be distorted?
No. The aspect ratio is fixed, you only choose the crop. If your subject doesn't fit the format at all, “Fit” places the whole image inside and fills the edges with a blurred version of the image.
Do location and camera data stay in the image?
No. When saving, metadata such as EXIF, GPS location and camera info is removed automatically. That protects you when you share images publicly.
Are my images uploaded?
No. With this tool, your image never leaves your device.
Is the tool free?
