Steam Avatar Size Resizer

Steam keeps your profile picture as a square in three sizes: 184 × 184 px (the full size, used on your profile page), 64 × 64 px (medium, for friends lists and chat) and 32 × 32 px (small lists). This tool turns any picture into a sharp 184 × 184 avatar: crop the part you want with zoom and position, or fit the whole picture on a background colour, and check how it looks at all three sizes on a dark Steam-style background before you upload it.

How to use this tool

1. Choose a picture — a face or logo with a clear outline works best at small sizes.
2. Keep "fill the square", then zoom and move the crop; or show the whole picture on a background.
3. Choose JPG or PNG.
4. Check the preview, then upload the 184 × 184 file in Steam under Edit Profile → Avatar.

Formula

crop side = shorter side × 100 ÷ zoom %; crop start = (longer side − crop side) ÷ 2 × (1 + position ÷ 100)

The square is resized in halving steps before the final 184, 64 and 32 px versions, so details stay smooth instead of jagged. In "show the whole picture" mode the image is scaled to fit inside the square and centred on the background colour. The 184 / 64 / 32 sizes are the full, medium and small avatar images Steam serves, as listed in Valve's Web API documentation.

Example

A 1920 × 1080 screenshot at 100% zoom gives a 1080 × 1080 crop starting at x = (1920 − 1080) ÷ 2 = 420, which is then reduced to 184 × 184. At 200% zoom the crop is 540 × 540 px from x = 690, y = 270 — a tighter close-up around the centre.
