How to Crop a Photo Into a Circle for a Profile Picture
Round avatars are everywhere — but most apps only display your photo in a circle while the file itself is still a square. When you need a genuinely circular image (for overlays, email signatures, slide decks, or apps that don't auto-mask), you need transparency. Here's how it works.
Why the format matters: PNG, not JPEG
A circle inside a rectangle leaves four corners that must be transparent — and only formats that support an alpha channel can store transparency. PNG can; JPEG cannot. Save a circular crop as a JPEG and the corners turn solid white or black. Always export circular images as PNG, which is exactly what our circle crop tool does.
Frame the face first
A circle crops in from the corners, so anything near the edges of a square gets cut. For a headshot:
- Center the face roughly in the middle of the frame.
- Leave breathing room — don't crop so tight that the top of the head or chin gets clipped by the circle.
- Start square. If your photo is very wide or tall, crop it to a square around the subject first, then circle-crop.
Recommended profile picture sizes
- Most social platforms: 400×400px is a safe, sharp minimum.
- High-DPI / retina displays: 800×800px looks crisper on modern screens.
- Favicons and tiny avatars: the image will be shown small, so keep detail simple.
Because a circle crop is square, just resize the square to your target before or after cropping with the resizer.
Keep it private
Profile photos are personal, and many carry hidden location data from your phone. Our circle crop runs entirely in your browser, so the image is never uploaded — and you can strip EXIF metadata too before posting it anywhere.
