Resize Image to 300×250
300×250 is the “medium rectangle” — the most widely supported display-ad size on the web. It fits in sidebars, between paragraphs and in mobile feeds, so almost every ad network accepts 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 300×250?
300×250 is a landscape image of 75,000 pixels (0.07 megapixels) in a 1.2:1 shape, mostly used for the IAB medium-rectangle display ad.
1.2:1 landscape shape
The 1.2:1 proportion decides how your photo is framed: plan the subject around that shape before you crop.
The exact size needed
300×250 is the exact size for the IAB medium-rectangle display ad, so your image is shown as-is instead of being re-scaled or cropped by the platform.
Prints 1×0.83 in at 300 DPI
That is 2.5×2.1 cm at photo quality, or 2×1.7 in at 150 DPI for posters viewed from a distance.
About 12 KB–23 KB as JPG
A typical photo at 300×250 saves to roughly 12 KB–23 KB at good JPG quality; WebP is usually 25–35% smaller.
Sharp results
A 12 MP phone photo has 163× more pixels than 300×250, so resizing down keeps it sharp.
Framing control
Filling 300×250 from a 4:3 phone photo trims about 10% of it. Drag the preview to choose what stays, or tick “Keep aspect ratio” to keep it all.

Making a 300×250 creative that works
Why it is everywhere. The 300×250 unit fits in content columns on desktop and within the width of a phone screen, so publishers use it in nearly every layout. If you only make one static ad size, this is usually the one.
Layout. A clear image, a short headline, your logo and a button-styled call to action. At 300 pixels wide, headline text below about 18 pixels becomes hard to read on a phone.
Design at 2×. Build at 600×500 and resize down here for crisper text and edges. Some networks also accept 600×500 for high-DPI screens.
File size limits. Static display ads are commonly capped around 150 KB. After resizing, check the file and use the compressor if needed.
Border. A 1-pixel border helps the ad separate from white page backgrounds, and some networks require it.
Same creative, other slots. The square 250×250 is the nearest standard size. For social ads, see 1200×628 and 1080×1080.

Frequently asked questions
Is 300×250 still a standard ad size?
Yes. The medium rectangle remains one of the most widely available display-ad sizes on desktop and mobile, and nearly every ad network supports it. Check each network's file-size limit, commonly around 150 KB.
What aspect ratio is 300×250?
300×250 has a 1.2:1 aspect ratio. Images with a different shape have to be cropped or padded to fit it.
How big will a 300×250 image print?
At 300 DPI (photo quality) 300×250 prints at 1×0.83 inches (2.5×2.1 cm). At 150 DPI it covers 2×1.67 inches, fine for posters seen from further away.
How large is a 300×250 file?
A photo at 300×250 is usually 12 KB–23 KB as a JPG, and about 8 KB–16 KB as WebP. If you need it smaller, run it through the compressor afterwards.
Will my photo lose quality at 300×250?
No — a normal phone photo is much larger, so it is scaled down and stays sharp.
Can I resize to 300×250 without cropping?
Yes. Tick “Keep aspect ratio”: the whole picture is kept, but one side may come out shorter than 300×250. Without it, the image fills 300×250 exactly and the edges that do not fit the 1.2:1 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.
