Follow the steps below with the free Circle Crop Image tool — it runs entirely in your browser, needs no upload, account or watermark, and finishes in about a minute.
Step by step
A circle is just an inscribed square — getting the 1:1 framing right decides everything.
The circle tool keeps full alpha outside the disc, so backgrounds stay transparent.
Only PNG carries the transparency; a JPEG export fills the corners white.
400×400 for avatars, 1024+ for print or slides.
Pro tips & common mistakes
- Faces: centre the circle slightly above the geometric middle — foreheads read better than chins.
- Logos with text need extra margin inside the disc or the curve clips letters.
- Drop the circle onto a coloured background in any editor for an instant profile banner.
