4:1 landscape shape
The banner 4:1 proportion decides how your photo is framed: plan the subject around that shape before you crop.
Where it is used
512×128 suits headers, banners and web-ad slots. Using the exact size avoids a website scaling or cropping your image on its own.
Prints 1.71×0.43 in at 300 DPI
That is 4.3×1.1 cm at photo quality, or 3.4×0.9 in at 150 DPI for posters viewed from a distance.
About 10 KB–20 KB as JPG
Expect around 10 KB–20 KB for a JPG photo at this size. Simple graphics are smaller, PNG photos several times larger.
Sharp results
A 12 MP phone photo has 186× more pixels than 512×128, so resizing down keeps it sharp.
Framing control
Filling 512×128 from a 4:3 phone photo trims about 67% of it. Drag the preview to choose what stays, or tick “Keep aspect ratio” to keep it all.

Working with a 4:1 strip
4:1 is very wide. Almost nothing is photographed in that shape, so 512×128 is usually made for a purpose: a health bar, a title plate, a row of four 128×128 icons, or a wordmark.
Sprite rows. Four 128×128 frames in a row fit exactly. If you are resizing an existing strip, keep the frame count in mind — scaling a 1024×256 strip to 512×128 halves each frame cleanly, but odd scale factors blur the frame boundaries.
Logos and title plates. Wordmarks often suit 4:1. Pad the logo on a transparent canvas of that ratio rather than stretching it. PNG keeps the transparency.
Cropping photos to 4:1. If you do want a photo in this shape — say, a narrow skyline strip — crop with the cropper first so you choose the band that stays. Otherwise the resizer will squash the image vertically.
Why power of two. Engines mipmap and wrap power-of-two textures most reliably. For plain web use it does not matter; for games, stick with it.

Frequently asked questions
How do I put four icons into one 512×128 image?
Make each icon 128×128 (see the 128×128 page), then place them side by side on a 512×128 canvas in any editor. Resizing a finished strip here works too, as long as the original frames were equal widths.
What aspect ratio is 512×128?
512×128 has a banner 4:1 aspect ratio. Images with a different shape have to be cropped or padded to fit it.
How big will a 512×128 image print?
At 300 DPI (photo quality) 512×128 prints at 1.71×0.43 inches (4.3×1.1 cm). At 150 DPI it covers 3.41×0.85 inches, fine for posters seen from further away.
How large is a 512×128 file?
A photo at 512×128 is usually 10 KB–20 KB as a JPG, and about 7 KB–14 KB as WebP. If you need it smaller, run it through the compressor afterwards.
Will my photo lose quality at 512×128?
No — a normal phone photo is much larger, so it is scaled down and stays sharp.
Can I resize to 512×128 without cropping?
Yes. Tick “Keep aspect ratio”: the whole picture is kept, but one side may come out shorter than 512×128. Without it, the image fills 512×128 exactly and the edges that do not fit the 4:1 shape are trimmed.
Are my images uploaded?
No. Resizing happens entirely in your browser. Nothing is transmitted or stored, and you can disconnect from the internet after the page loads and it still works.
