How to use it
- Choose or drop a picture.
- Use Zoom and the two position sliders until the circle shows what you want.
- Pick an output size and press Download circle PNG.
How it works
The circle shows a square window of your photo. At zoom 1 the window is the largest square that fits, that is as wide as the shorter side. Zoom divides that side: at zoom 2 the window is half as wide. The position sliders move the window within the photo. The window is drawn into a square canvas, everything outside a circle is clipped away and the canvas is saved as PNG.
Example
An 800 × 600 photo at zoom 1 gives a 600 × 600 window, starting 100 px from the left when the left–right slider is at 50. At zoom 2 the window is 300 × 300; with both sliders at 0 it shows the top-left corner of the photo.
Tips
- Most services crop avatars to a circle themselves, so keep the subject away from the edge of the circle.
- Use at least 512 px for a profile picture that stays sharp on large screens.
