Simple geometry
The centered circle uses the full square canvas, producing a predictable diameter and output dimension.

Why this square to circle image workflow is different
Every control changes the downloaded image. There are no decorative preview buttons, hidden signup gates, or server upload steps.
Transparent corners
PNG and WebP remove the four square corners outside the round boundary.
Fill or preserve
Choose whether the source should occupy the whole circle or remain completely visible.
Optional circular border
Add a precise ring after converting the square image, without another editing step.
Real output patterns
Circle crop examples and safe-area previews
These language-neutral examples show the kinds of spacing, transparency, and border choices the tool produces.
Square to circle
Remove the visible corners while keeping the center unchanged.
Transparent output
Choose PNG or WebP for reusable transparent corners.
Optional border
Finish the conversion with a scalable circular ring.
How to Convert a Square Image Into a Circle
A square-to-circle conversion keeps the square canvas but makes the four outer corners transparent or fills them with a background color. The visible diameter matches the square output size. Upload the source, confirm the center, and export in a format that supports the intended background.
No permanent change is made to the original file. The browser creates a new circle image when you download.
Fill Circle vs Fit Full Square Image
Fill circle is the common choice for photos because the subject occupies the complete round frame. Fit full image is useful for a square logo or artwork with important corner details, but extra background space is needed to keep those corners inside a circle.
The live preview makes this tradeoff visible. There is no single mode that can both fill a circle and preserve every corner of a square source.
Transparent Square-to-Circle Output
Choose PNG or WebP when the new circle needs transparent outer corners. The checkerboard shows those pixels. Choose JPG only when a fixed square background is acceptable, because JPG cannot represent alpha transparency.
For logos and icons, PNG provides a reliable master. For photographic web assets, WebP can reduce file size while keeping transparent corners.
Use a Square-to-Circle Image in Profiles and Layouts
Round outputs fit profile pictures, team directories, testimonial cards, author bios, app icons, labels, and badges. Check the destination mask and leave enough safe spacing around faces or text.
If the source is rectangular rather than square, the same tool still works. Fill mode covers the circle, while Fit mode preserves the full rectangle with additional background space.

Convert a Square to Circle Image Online FAQ
Direct answers cover formats, privacy, quality, mobile use, and the failure cases that cause most repeat edits.
How do I convert a square image into a circle?
Upload the square file, keep it centered or adjust the position, choose PNG or WebP, and download the circular result.
Does converting square to circle cut off the corners?
Fill mode removes the visible square corners outside the circle. Fit mode can preserve the full square inside the circle by adding background space.
Can a square-to-circle image stay transparent?
Yes. PNG and WebP keep the outer corners transparent. JPG replaces those corners with the selected background color.
Can I add a border after converting the image?
Yes. Increase Border width and choose a solid or gradient ring before downloading.
Will the output still be a square file?
Yes. Raster images use a square canvas, while transparency or background color makes the visible subject circular.
Can I convert a rectangular image too?
Yes. The cropper can fill the circle with a rectangle or fit the complete source inside it. The square page focuses on the most predictable input shape.
Is the square to circle image converter free?
Yes. The square to circle image converter is free, requires no signup, and creates the download locally in your browser.
Can the square to circle image keep its original size?
Yes. Choose Original crop or enter a custom dimension. The square to circle image is redrawn from the source rather than captured from the preview.
