Crop any photo into a circle

A circular crop takes a rectangular photo and masks it into a clean round shape, keeping only the area inside the circle and making everything outside it transparent. It is the fastest way to create a round profile picture, a community avatar, a team headshot, or a circular sticker without opening a heavyweight photo editor. Because the result is saved as a PNG with a transparent background, the round image drops neatly onto any color, gradient, or photo behind it with no visible square edges.

Circular avatars are everywhere. Slack, Discord, Microsoft Teams, WhatsApp, Google accounts, Gmail, YouTube channels, and countless forums and apps display your profile photo inside a circle. If you upload a square image, those platforms crop the corners for you — but the edges of your subject can end up clipped in ways you did not intend. Cropping the circle yourself first lets you control exactly what stays in frame, so your face or logo is centered and nothing important is lost to an automatic mask.

Pixohub crops the circle entirely inside your browser using the HTML Canvas API. Your image is drawn onto a canvas, a circular clipping path is applied, and the area outside the circle is erased to transparency before the result is encoded as a PNG. Nothing is uploaded to a server, so the process is instant, completely private, and works even on a slow connection or fully offline once the page has loaded.

Why the output is a transparent PNG

The corners of a circular crop have to be transparent, otherwise you would see an ugly square box of background color around the circle wherever you placed it. PNG is the right format for this because it supports a full alpha channel, meaning each pixel can be fully opaque, fully transparent, or anywhere in between. JPG, by contrast, cannot store transparency at all and would fill the corners with a solid color, so Pixohub always exports circle crops as PNG.

The transparent corners make the round image genuinely reusable. You can layer it over a colored header, place it inside a card component, drop it onto a banner, or combine several avatars into a group graphic, and the background always shows through cleanly. For crisp results, start from a photo that is at least as large as the size you plan to display — a source image of 512x512 pixels or more keeps the edge of the circle smooth and avoids a jagged, pixelated rim when the avatar is shown large.

A practical workflow is to frame your subject slightly smaller than the full circle so there is a little breathing room around the head or logo, since some platforms add their own border or shrink the image inside a ring. Once you are happy with the framing, export the PNG and upload it wherever you need a round picture. Because the file is a standard transparent PNG, it works in profile settings, design tools like Figma and Canva, presentation slides, and web pages alike.

Frequently asked questions

Does the circle crop have a transparent background?

Yes. The area outside the circle is fully transparent, and the result is saved as a PNG so those transparent corners are preserved. You can place the round image over any color or photo without a visible square box.

Why is the file a PNG and not a JPG?

JPG cannot store transparency, so it would fill the corners of the circle with a solid color. PNG supports a transparent alpha channel, which is exactly what a circular crop needs, so Pixohub always exports circle crops as PNG.

Are my photos uploaded to a server?

No. The crop is performed locally in your browser using the Canvas API. Your image never leaves your device, which makes it safe for personal photos and private headshots.

What size should my photo be for a good avatar?

Start from an image that is at least 512x512 pixels for a sharp result. Larger source photos keep the edge of the circle smooth; very small images can look jagged around the rim when displayed large.

Can I use this for Slack, Discord or Gmail profile pictures?

Yes. Those platforms all display avatars in a circle. Cropping the circle yourself first lets you control the framing so nothing important gets clipped by their automatic mask.

Is it really free with no watermark?

Yes. Every tool on Pixohub is completely free with no account, no watermark, and no limit on the number of images you crop.

Does it work on my phone?

Yes. Pixohub is fully responsive and runs in any modern mobile browser, including Safari on iOS and Chrome on Android.
