Resize an image to 150x150 pixels

Where 150x150 shows up

It is a 1:1 square, so width and height match. WordPress creates a 150x150 thumbnail for every upload, classic forums use it for avatars, and plenty of dashboards reserve a 150 pixel box for a profile picture.

Because the box is small, the safe move is a tight crop. A headshot or a single object reads clearly at 150 pixels, while a wide scene loses everything once it shrinks this far. The resize tool is preset to 150 by 150 if you want to confirm the numbers.

Crop square before you shrink

Most photos are taller or wider than they are square, so something gets cut when you force 1:1. Keep the subject centered so the crop takes from the edges, not the face.

If the subject sits off to one side, recompose first so it lands in the middle of the 150x150 frame. A quick preview check saves a re-export when the thumbnail turns out to be mostly background.

It is already a tiny file

A 150x150 JPEG is usually well under 30 KB, so size is rarely the problem at this dimension. If a form still complains, compress it to an exact KB target to clear the cap.

Everything runs on your own machine. The image is processed in the browser and never uploaded, so private photos stay private.
