Tips for resizing ad designs
- Start big. Use your largest version, ideally 2000 px or more, so smaller sizes stay sharp.
- Very wide and very tall sizes need their own layout. A square design squeezed into 728×90 or 160×600 rarely works. Use these files as a starting point, and ask your designer to adjust text and logo placement for those shapes.
- Choose “Fit” for logos and text-heavy designs so nothing is cut off, and pick a background colour that matches your design.
- JPG for photos, PNG for flat graphics with text. The 150 KB option lowers JPG quality only as much as needed.
Questions
Is my image uploaded?
No. Resizing happens inside your browser, so your design never leaves your device.
Why does a size look blurry?
Your original is smaller than that size, so it had to be enlarged. We mark these with a warning. Use a bigger original.
Why is a PNG banner over 150 KB?
PNG files can’t be compressed like JPGs. Switch to JPG for display banners, or simplify the design.
