300 x 300 Resizer
300 x 300 pixels is a compact utility square for thumbnails, gallery tiles, chat avatars, and preview images. At this size files are tiny and pages stay fast — the trade-off is that it only looks sharp at small display sizes, so it works as a derivative of a larger master, not as the master itself.

Small Square, Big Utility
Thumbnails, chat avatars, comment-section profile photos, and dense gallery grids all display near or below 150 pixels — a 300 x 300 export covers them with double-density sharpness.For pages that render long lists of images, small squares like this are the difference between a fast page and a slow one.
Crop Tight, Keep It Legible
At small display sizes, wide shots turn into unreadable specks. Crop close to the subject before resizing down to 300 x 300.Avoid small text inside the image — anything below the main subject scale disappears at thumbnail size.
A Derivative, Not a Master
Export 300 x 300 from a larger original and keep that original; you can always regenerate the small square, but you cannot enlarge it later without softness.If the same image might ever be shown large, produce both sizes up front and let each placement load the one it needs.
