300×300 — avatars, badges and small thumbnails

300×300 is the avatar standard for forums, Slack profiles, comment systems and Indian competitive-exam portals. Tiny pixel count means file size stays under almost every cap.

Why 300 by 300 is still everywhere

You need a small square image at exactly 300 by 300 pixels.

300 by 300 is a square that has survived every redesign of the web because it is the smallest size that still reads clearly as a face or a product at typical screen densities. Forum avatars, directory portraits, marketplace thumbnails and app store icons all cluster around it. Because it is square, any rectangular source has to be reconciled with the frame: fitting the whole picture keeps every edge visible, which matters when the image is a document or a logo rather than a face.

When people use this tool

Avatars and profile photos

Community platforms and internal directories display members at roughly this size.

Marketplace thumbnails

Product grids use small squares so a long listing page stays fast.

App and launcher icons

Several icon specifications sit at or near 300 pixels square.

Step-by-step

1 Upload the image. Any common image format is accepted and read locally.
2 The square is applied. Your picture is fitted inside a 300 by 300 canvas so nothing is cut off.
3 Check the subject size. For a portrait, the face should fill a comfortable share of the square rather than sitting tiny in the middle.
4 Download. The file is exactly 300 pixels wide and 300 pixels tall.

Practical tips

• Crop to a square first if you want the subject to fill the frame edge to edge.
• Faces read better when the head occupies most of the height of the square.
• At this size, fine text becomes unreadable; simplify logos before scaling down.
• Avoid enlarging an image that is already smaller than 300 pixels.
