How to crop an image online
- Add your image, drag and drop it onto the box, click to browse, or paste it from your clipboard. It is decoded instantly on your device.
- Pick a shape, leave it on Rectangle for a normal crop, or switch to Circle for a round crop, handy for profile pictures and avatars.
- Choose an aspect ratio, leave it on Free to crop to any shape, or lock the box to 1:1, 4:3, 16:9, 3:2 or 2:3 for profile pictures, thumbnails, banners and prints. Circle crops always use a square selection, so the ratio lock is disabled while Circle is selected.
- Position the crop box, click or drag directly on the preview to move it, or type exact X, Y, Width and Height values for pixel-precise control. The shaded overlay and rule-of-thirds guides show exactly what will be kept.
- Crop and download, click Crop & download to save just the selected region to your device. Circle crops always download as PNG so the area outside the circle stays transparent.
Pick the right aspect ratio
The aspect ratio is the relationship between an image's width and its height. Many platforms expect a specific shape, and cropping to the right one stops your picture from being squashed or awkwardly auto-cropped later. A 1:1 square suits avatars and most social profile photos. 16:9 is the standard for video thumbnails, slides and widescreen banners, while 4:3 and 3:2 match classic camera and print sizes. Choose 2:3 for tall portrait shots. When a ratio is locked, the height follows the width automatically, so the box always keeps the correct proportions as you move it.
Cropping changes the visible area, not the resolution of what remains, the kept pixels are untouched. If you also need to change the pixel dimensions or file size afterwards, try the image resizer or the image compressor. Need to rotate or mirror first? Use rotate & flip image.
Frequently asked questions
What file format do I get back?
The original format is kept for JPG, PNG and WebP. Other formats (such as GIF or BMP) are downloaded as a JPG. Circle crops always download as PNG, since the transparent area outside the circle needs an alpha channel.
Does cropping lower the quality?
No. Cropping keeps the pixels inside your selected rectangle exactly as they are. PNGs stay lossless and JPEGs are re-saved at high quality.
Can I enter exact pixel coordinates?
Yes. Type the X, Y, Width and Height values to crop to an exact region, or just click and drag on the preview for a quick visual crop.
Can I crop a photo into a circle?
Yes. Set Shape to Circle, position the square selection over the part you want to keep, then crop and download. The result is a PNG with the area outside the circle made transparent, ideal for profile pictures and avatars.
