How to Crop a Photo Into a Perfect Circle

Apps mask avatars into circles themselves, so why crop one? Because when you control the circle — centring it on a face exactly — the app mask cannot chop off a chin or an ear. A transparent PNG circle also drops straight into slides and collages.

The short version

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

1
Centre-crop to a square first

A circle is just an inscribed square — getting the 1:1 framing right decides everything.

2
Apply the circle crop

The circle tool keeps full alpha outside the disc, so backgrounds stay transparent.

3
Export PNG

Only PNG carries the transparency; a JPEG export fills the corners white.

4
Resize for the job

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.

Frequently asked questions

Why are my circle-cropped corners white?
You exported JPEG. Use PNG to keep the outside-disc area transparent.
Will this beat the automatic app mask?
Yes, because you choose what stays inside — apps always use the geometric centre.
Can I circle-crop a product photo?
Absolutely — square-crop around the product first, then apply the circle.
