About this tool
Crop one square source into circle-safe profile pictures at each platform's recommended upload size, entirely in your browser.
Brand Social Avatar Kit Generator crops one square master image into profile pictures at each platform's recommended upload size and shows the circle-safe area before you export. Because every major network masks a square avatar to a circle, only the centred square of 70.71% of the width — the largest square that fits inside an inscribed circle — is guaranteed to survive; the preview draws that boundary so a wordmark never loses its edges. Cropping and PNG export happen entirely in the browser, so the image is never uploaded.

The 70.71% safe square is drawn from the geometry of an inscribed circle, not guessed.
Cropping and PNG encoding use the canvas API in your own browser.
Flags any platform whose target size is larger than the crop you actually have.
Export a square image at least 400 × 400 px for X and LinkedIn, 320 × 320 for Instagram and Facebook, and 800 × 800 for YouTube. Keeping a 1600 × 1600 master covers every current target at 2× so the same file survives the next round of platform changes.
The corners. A circle inscribed in a square touches all four edges, so the largest square that stays fully visible has a side of 1/√2 — about 70.71% — of the image width, leaving a 14.64% margin on each edge. Anything in that margin can be clipped.
Give it a solid background. Platforms composite avatars over light and dark chrome, and a transparent PNG can leave a dark mark invisible in dark mode. Export one solid version for social and keep the transparent original as the master.
Usually because the source was smaller than the display size and got upscaled, or because the platform re-compressed a JPEG. Upload a PNG at or above the recommended size — this tool flags any platform where your crop is smaller than the target.
