What this tool does
Crops, resizes, or rounds the corners of an image directly in your browser. Drag to select a crop area, enter exact pixel dimensions with optional aspect-ratio locking, or round the corners with an adjustable radius, then download the result as a PNG.
How It Works
Crop copies only the pixels inside your dragged selection into a new, smaller canvas, discarding everything outside it. Resize draws the current image onto a canvas of your chosen width and height, letting the browser's built-in image scaling handle the pixel resampling, with aspect-ratio lock computing the matching height (or width) whenever you change the other value. Round Corners tests every pixel's position against a rounded-rectangle shape (the four corner regions are quarter-circles of your chosen radius, everything else is a straight edge) and makes any pixel that falls outside that shape fully transparent.
Problems it solves
- Cutting out an unwanted border, background, or distracting element from a photo.
- Resizing an image to fit exact dimensions required by a website, form, or platform.
- Creating a rounded-corner avatar, icon, or card image for a UI design.
Frequently asked questions
›Can I crop, then resize, then round the corners of the same image?
Yes. Each mode works on the current state of the image, so cropping first and then switching to Resize will resize the cropped result, not the original. Round Corners is the one exception, it's always a live preview of the final look and isn't "baked in" until you download, so it makes the most sense as your last step.
›Why do I need to click "Apply Crop" or "Apply Resize" instead of seeing the result instantly?
Cropping and resizing change the image's actual pixel dimensions, not just how it looks, so committing them as a deliberate step avoids accidentally shrinking or cutting your image while you're still deciding on a selection or size. Round Corners doesn't change the dimensions, only which pixels are visible, so it can safely update live as you drag the slider.
›What happens if I turn off "Lock aspect ratio" in Resize?
The width and height fields become independent, letting you stretch or squash the image to any dimensions you enter, useful if you specifically need a non-proportional size, but it will distort the image if the new ratio doesn't match the original.
›Why does Round Corners download as a PNG?
Rounding the corners works by making the pixels outside the rounded shape fully transparent. JPEG doesn't support transparency, so the result is always saved as a PNG, which does, keeping the rounded corners see-through instead of showing a solid color behind them.
›Is my photo uploaded anywhere?
No. Cropping, resizing, and corner rounding all happen locally in your browser using the HTML canvas API. Nothing is sent to a server.
