Resize Image to 400×150
400×150 is a compact 8:3 banner — wide enough for a logo with a tagline, small enough to sit in a sidebar, card or header slot. Plugin listings, directories and themes often ask for it. Everything runs in your browser — nothing is uploaded. Need a smaller file instead? Compress or convert.
Drag the preview to choose which part of the image is kept. The same framing is used for every image in the batch.
Why choose 400×150?
At 400×150 pixels, an image holds 0.06 megapixels in a 2.67:1 ratio. It is a common choice for headers, banners and web-ad slots.
2.67:1 landscape shape
The 2.67:1 proportion decides how your photo is framed: plan the subject around that shape before you crop.
Where it is used
400×150 suits headers, banners and web-ad slots. Using the exact size avoids a website scaling or cropping your image on its own.
Prints 1.33×0.5 in at 300 DPI
That is 3.4×1.3 cm at photo quality, or 2.7×1 in at 150 DPI for posters viewed from a distance.
About 9 KB–19 KB as JPG
A typical photo at 400×150 saves to roughly 9 KB–19 KB at good JPG quality; WebP is usually 25–35% smaller.
Sharp results
A 12 MP phone photo has 203× more pixels than 400×150, so resizing down keeps it sharp.
Framing control
Filling 400×150 from a 4:3 phone photo trims about 50% of it. Drag the preview to choose what stays, or tick “Keep aspect ratio” to keep it all.

Designing for a 400×150 slot
A logo plus a line. 8:3 gives room for a horizontal logo and a short tagline, or a symbol beside a name. Anything more crowded becomes unreadable at 150 pixels tall.
Resize the whole design, not the logo. If you place a square logo in this slot by typing 400 and 150, it will be squashed flat. Put the logo on a 400×150 canvas with padding in your editor, or crop your source image to 8:3 with the cropper, then resize here.
Directories and listings. Business directories, app listings and sponsor walls often use fixed-size banner slots. Matching the size exactly avoids the site cropping your logo off-centre.
Text size. Keep lettering at least 18–20 pixels tall so it survives phones and compression.
Format. PNG for logos and flat graphics, especially if the slot has a coloured background you want to show through. JPG if the banner is a photo.

Frequently asked questions
What aspect ratio is 400×150?
400×150 has a 2.67:1 aspect ratio. Images with a different shape have to be cropped or padded to fit it.
How big will a 400×150 image print?
At 300 DPI (photo quality) 400×150 prints at 1.33×0.5 inches (3.4×1.3 cm). At 150 DPI it covers 2.67×1 inches, fine for posters seen from further away.
How large is a 400×150 file?
A photo at 400×150 is usually 9 KB–19 KB as a JPG, and about 7 KB–13 KB as WebP. If you need it smaller, run it through the compressor afterwards.
Will my photo lose quality at 400×150?
No — a normal phone photo is much larger, so it is scaled down and stays sharp.
Can I resize to 400×150 without cropping?
Yes. Tick “Keep aspect ratio”: the whole picture is kept, but one side may come out shorter than 400×150. Without it, the image fills 400×150 exactly and the edges that do not fit the 2.67:1 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.
