Google Display Ad Resizer

Google Ads Help lists 20. Boxes: 200 × 200, 240 × 400, 250 × 250, 250 × 360, 300 × 250, 336 × 280, 580 × 400. Tall: 120 × 600, 160 × 600, 300 × 600, 300 × 1050. Wide: 468 × 60, 728 × 90, 930 × 180, 970 × 90, 970 × 250, 980 × 120. Small: 300 × 50, 320 × 50, 320 × 100. Some are regional.

150 KB per image, as GIF, JPG or PNG. The tool counts 1 KB as 1,000 bytes and rounds sizes up, so "150 KB of 150 KB" is never over, even if Google counts 1,024-byte kilobytes. JPG usually gets photos under the limit; PNG is lossless and often larger.

Google lists the sizes without ranking them, and so does this tool. All 20 come from one upload, so untick only the ones your design can't fill, like a 970 × 90 strip cut from a square product photo.

The shapes range from a 1:5 skyscraper to a 10.78:1 strip, so no photo fits all 20. A square photo keeps under half of itself in 12 sizes on Fill and crop. Move the focus, or use Fit inside to keep the whole image and set the background colour under More options.

No. The tool writes still JPG or PNG files and uses the first frame of an animated upload. Google requires animated GIFs to run 30 seconds or shorter, slower than 5 frames per second.

No. Responsive display ads use a 1.91:1 image (1200 × 628 recommended, at least 600 × 314) and a 1:1 image (600 × 600 recommended, at least 300 × 300), and Google builds the ad. This tool makes fixed-size banners you upload as image ads.
