Why crop to a transparent circle?
Almost every modern platform shows your avatar inside a circle — social profiles, Discord, Slack, forums, messaging apps and comment sections. But the photo you upload is a rectangle, so the platform crops it on the fly, and the result is often off-center or awkwardly cut. Pre-cropping your image into a circle yourself guarantees it looks right everywhere, because you decide exactly what stays inside the frame.
This tool takes the largest centered square of your picture, scales it to your chosen size, and then erases everything outside a perfect circle. The corners become fully transparent rather than white or black, which is why the export has to be a PNG. A transparent PNG sits cleanly on any background — a dark sidebar, a colourful banner, a website header or a printed page — with no ugly box around your face or logo.
What size should you export?
For a profile picture, 512 × 512 px is the sweet spot: it stays crisp on high-resolution screens without being a huge file. Choose 256 px for tiny icons and favicons, or keep the original square if you need the maximum possible detail for print or large display. Because the crop is always a centered square, the circle never stretches or distorts your image.
Is it private and safe?
Yes. Toolyard does all the cropping inside your browser using your own device. Your images are never uploaded to any server, so nothing can be stored, seen or leaked — which matters when the picture is your own face. You can even keep working offline once the page has loaded, and there are no watermarks, sign-ups or limits.
Frequently asked questions
Why does it export a transparent PNG?
A circle is round but image files are rectangular, so the corners outside the circle must be see-through. Only PNG can store that transparency — JPG would fill the corners with a solid colour. The transparent PNG drops cleanly onto any background.
Does it work for any image?
Yes. The tool automatically takes the largest centered square of your picture and cuts a circle from it, so tall, wide or square photos all work. Center your subject before cropping for the best result.
What output size should I use?
512 pixels is a safe choice for most avatars — Discord, Slack, forums and social profiles all look sharp at that size. Pick 256 for smaller icons, or keep the original square for maximum detail.
Are my images private?
Completely. The cropping runs inside your browser on your own device, so your images are never uploaded to any server. Nothing is stored, seen or shared.
Can I crop several images at once?
Yes. Drop as many images as you like, crop them all in one go, then use Download all to save every circular PNG at once.
