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 12×18?
12×18 is a portrait image of 216 pixels (0 megapixels) in a portrait 2:3, mostly used for ID photos, small thumbnails and form uploads.
2:3 portrait shape
Every 12×18 image has a portrait 2:3 ratio, so anything you design for it keeps the same proportions on every screen.
Where it is used
12×18 suits ID photos, small thumbnails and form uploads. Using the exact size avoids a website scaling or cropping your image on its own.
Prints 0.04×0.06 in at 300 DPI
That is 0.1×0.2 cm at photo quality, or 0.1×0.1 in at 150 DPI for posters viewed from a distance.
About 0 KB–0 KB as JPG
A typical photo at 12×18 saves to roughly 0 KB–0 KB at good JPG quality; WebP is usually 25–35% smaller.
Sharp results
A 12 MP phone photo has 56,448× more pixels than 12×18, so resizing down keeps it sharp.
Framing control
Filling 12×18 from a 3:4 phone photo trims about 11% of it. Drag the preview to choose what stays, or tick “Keep aspect ratio” to keep it all.

Working at 12×18 pixels
Design it, don't shrink it. A photo squeezed into 216 pixels turns into a coloured smudge. At this size every single pixel is a decision, so the best results come from artwork drawn for it — a character sprite, a map marker or a counter icon with two or three flat colours.
Save as PNG. JPG blurs hard pixel edges and adds noise around them. PNG keeps each pixel exactly the colour you set, and supports a transparent background for sprites.
Scale up by whole numbers to preview. Shown at 4× it becomes 48×72; at 8×, 96×144. Whole-number steps keep the pixels square and crisp.
12×18 inch posters are a different job: the same 2:3 shape, but at 300 DPI they need 3600×5400 pixels. Double both sides and you get the 24×36 poster. For small printed portraits, see 1.18×1.57 inch.

Frequently asked questions
How many pixels do I need to print a 12×18 inch poster?
About 3600×5400 pixels at 300 DPI. At 150 DPI, which still looks fine from a few feet away, 1800×2700 is enough.
What aspect ratio is 12×18?
12×18 has a portrait 2:3 aspect ratio. Any size with the same ratio — for example 24×36, 16×16 — can be scaled to it without cropping.
How big will a 12×18 image print?
At 300 DPI (photo quality) 12×18 prints at 0.04×0.06 inches (0.1×0.2 cm). At 150 DPI it covers 0.08×0.12 inches, fine for posters seen from further away.
How large is a 12×18 file?
A photo at 12×18 is usually 0 KB–0 KB as a JPG, and about 0 KB–0 KB as WebP. If you need it smaller, run it through the compressor afterwards.
Will my photo lose quality at 12×18?
No — a normal phone photo is much larger, so it is scaled down and stays sharp.
Can I resize to 12×18 without cropping?
Yes. Tick “Keep aspect ratio”: the whole picture is kept, but one side may come out shorter than 12×18. Without it, the image fills 12×18 exactly and the edges that do not fit the 2:3 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.
