Resize an image to 728×90 pixels
To resize an image to 728×90 px, enter 728 × 90 px and pick crop to fill so the 364:45 (8.09:1) frame is not stretched: a 4:3 phone photo loses 83.5% of its area (a centred 4032×498 crop). The result has 0.0655 megapixels; as a JPEG, a detailed outdoor photo is about 22.8 KB at the panel's default quality 85 (17.1 KB at quality 75).

What 728×90 means in pixels
728×90 is a landscape frame, 8.09 times as wide as it is tall, 65,520 pixels in total (0.0655 megapixels). Its sides reduce to 364:45, an 8.09:1 strip that no camera or screen shape comes close to, so every photo needs a heavy crop to fill it.
A 12 MP phone photo has 186 times as many pixels, so reaching 728×90 is a clean reduction with no invented detail. Shown 1:1 it fills 728×90 CSS px on a standard screen and 364×45 CSS px on a 2× (Retina-class) screen; at 72 DPI the same pixels span 10.1×1.3 inches.
Decoded for editing it occupies 256 KB of memory (4 bytes per pixel); uncompressed 24-bit RGB would be 192 KB, which is why the downloadable JPEG, PNG or WebP is far smaller.
Getting 728×90 from a phone, camera or screenshot
Filling 728×90 from a Full HD screenshot (1920×1080, 16:9) loses the least (78.1%); a vertical phone video frame (1080×1920, 9:16) loses the most (93%). "Fit inside" keeps the whole picture instead and the file comes out at the size in the last column; "Pad with colour" adds bars to reach the full 728×90. From the phone photo PixelFit takes the 4032×498 crop through 2016×249 and 1008×124 before the last step to 728×90, so each pass blends neighbouring pixels instead of skipping them.
| Starting image | Crop to fill keeps | Area lost | Scale | Fit inside gives |
|---|---|---|---|---|
| 12 MP phone photo (4032×3024, 4:3) | 4032×498 (top and bottom cut) | 83.5% | 0.181× (reduced) | 120×90 |
| 24 MP camera photo (6000×4000, 3:2) | 6000×742 (top and bottom cut) | 81.5% | 0.121× (reduced) | 135×90 |
| Full HD screenshot (1920×1080, 16:9) | 1920×237 (top and bottom cut) | 78.1% | 0.379× (reduced) | 160×90 |
| Vertical phone video frame (1080×1920, 9:16) | 1080×134 (top and bottom cut) | 93% | 0.674× (reduced) | 51×90 |

How to resize a picture to 728×90
-
Add the picture
Drop, paste or pick the photo in the PixelFit panel at the top of this page; it is decoded in your browser and never uploaded.
-
Set the size
Enter 728 as the width and 90 as the height in pixels (the panel is already set to 728×90).
-
Choose how it fits
Choose crop to fill to keep the 364:45 (8.09:1) frame without stretching (a phone photo loses 83.5%, top and bottom cut). Fit inside keeps the whole picture as a 120×90 file instead; Pad with colour puts that on a full 728×90 canvas.
-
Pick the format and download
Choose JPG or WebP; without a KB limit PixelFit saves JPG at quality 85, about 22.8 KB for a detailed outdoor photo. Add a KB limit if the upload has one or the file should be smaller, then download the 728x90 file.

Frequently asked questions
How do I resize an image to 728x90?
Open the image in the PixelFit panel on this page, set 728 × 90 px, choose crop to fill so nothing is stretched and download. From a 12 MP phone photo that crops 83.5% (top and bottom cut) and scales the rest by 0.181×.
What aspect ratio is 728x90?
728x90 has an aspect ratio of 364:45 (8.09:1): landscape, width ÷ height = 8.0889. No other common target has exactly this ratio: the frame is 8.09 times as wide as it is tall, and the closest familiar shape is 3:1, 169.6% away, so converting between them means a visible crop.
Is 728x90 good for print?
At 300 DPI 728x90 prints 2.43×0.3 in (6.2×0.8 cm). At 150 DPI it stretches to 4.85×0.6 in.

For a detailed outdoor photo about 17.1 KB at quality 75 (12.9 KB at 60, 27.9 KB at 90, 22.8 KB at the panel's default quality 85); a head-and-shoulders portrait is about 13 KB at quality 75, estimated from measured encodes. A flat graphic is smaller, a noisy low-light photo larger.
How does 728x90 look on a high-density screen?
On a 2× screen 728x90 is sharp when shown at 364×45 CSS px; shown larger, the browser enlarges it. A slot of 728×90 CSS px on a 2× screen needs a 1456×180 file.
