Non-square photos
If the original photo is not square, forcing it into a square shape would stretch it. Turn off “Lock aspect ratio” only if you really want that. Otherwise use “Crop to fill”, which trims the edges so the center of the photo fills the square, or “Fit inside”, which keeps the whole image and adds a white or transparent border.
Resize image to 300x300 and under 100 KB
Some forms and websites ask for a 300x300 JPG that is also below a file size such as 100 KB. Add your photo, keep the size at 300 × 300, switch compression to “Max file size” and type 100. Press “Apply”: the tool picks the highest JPG quality that stays under the limit and shows the final size in KB before you download.
A 300×300 photo saved as JPG is usually far smaller than the original, so most limits are easy to reach without visible quality loss. PNG files are larger; choose JPG when you have a KB limit.
300x300 pixels in inches and aspect ratio
300 × 300 pixels is a 1:1 (square) aspect ratio. Its size in inches depends on the DPI: at 300 DPI (print) it is 1 × 1 inches, and at 96 DPI (a typical screen) it is about 3.13 × 3.13 inches. Websites and apps only look at the pixel size, so 300x300 px is what matters online.
