How this works in your browser
The image is drawn onto a square canvas and a circular clipping path is applied, so only pixels inside the circle are painted and everything outside is left fully transparent rather than filled with a colour. The output has to be PNG for this to survive, because PNG carries an alpha channel and JPEG does not: saving the same result as JPEG would force those transparent corners to become opaque, almost always white. That is the single detail that decides whether a rounded image drops cleanly onto a coloured background or arrives sitting in a visible box.

Who uses Round Image
Creating an avatar
Produce a circular profile image for a site or document that does not apply its own mask.

How to use Round Image
- 1
Open the Round Image tool
Go to tools.slaytic.com and open the Round Image tool. No sign-up or account required.
- 2
Frame the square selection
Drop your image and reposition it so the part you want sits inside the square, since the circle is inscribed within it.
- 3
Download the PNG
Save the result as PNG, which preserves the transparent area outside the circle.
Frequently asked questions
What format is the output?
PNG, since it needs a transparent background outside the circular area.
Can I adjust which part of the image is inside the circle?
Yes, reposition and crop the image before applying the circular mask.
Will this work for a non-square image?
Yes. You will crop to a square selection first, then the circular mask is applied.
Why does my rounded image show a white box on some sites?
Because that site is not honouring the transparency. The corners really are transparent, but if the image gets converted to JPG somewhere in the upload pipeline, or is placed on a platform that flattens transparency, those corners fill with white. Keep the file as PNG and check the platform supports transparent images.
Do I even need this for a profile picture?
Often not. Most platforms apply their own circular mask to whatever you upload, so a plain square image is fine and gives them the most to work with. Rounding it yourself matters when you need the circle baked in, such as for a slide, a document or a website you control.
Can I get a rounded rectangle rather than a full circle?
The tool applies a circular mask. For softly rounded corners on a rectangular image, apply a CSS border-radius where it is displayed instead, which keeps the underlying image intact.
Is my image uploaded anywhere?
No. The mask is applied on a canvas inside your browser tab.
