About the Image Cropper
This tool cuts out a rectangular part of an image. You choose the left and top offset in pixels, set the crop width and height, then download the cropped result as a PNG. It is useful for trimming screenshots, removing empty borders, making avatars, focusing on one product in a photo or preparing an image for a fixed layout.
How to use it
- Load a PNG, JPEG or WebP image.
- Enter the crop rectangle in pixels, or use the center square shortcut.
- Click crop and review the preview.
- Download the cropped PNG.
The crop rectangle is clamped to the original image, so values outside the edges are pulled back into range. Cropping itself does not invent pixels or rescale the image; it only keeps the selected area. Saving as PNG preserves transparency when the browser decoded it. All processing happens with the Canvas API in your browser, so your image is never uploaded.
Frequently asked questions
Can I crop an image to a square?
Yes. Use the center square button for the largest centered square, or enter the same width and height manually for a custom square crop.
Does cropping reduce image quality?
The crop operation only keeps selected pixels, so it does not blur or stretch the image. The downloaded PNG is re-encoded by the browser.
What happens if the crop rectangle goes outside the image?
The tool clamps the rectangle to the image bounds so the output always contains valid pixels from the original.
Is my image uploaded when I crop it?
No. The image is decoded, cropped and saved locally in your browser, so the file never leaves your device.
