Crop an image to 4:3
Crop photos to the classic 4:3 ratio with a live preview and locked proportions. Everything is processed locally in your browser.
Privacy-first: every image is processed locally in your browser. Nothing is uploaded, stored or transmitted to any server.
The native ratio of most cameras
4:3 is what phone sensors and Micro Four Thirds cameras actually capture, and what older displays, iPads and many print formats expect. Cropping stray compositions back to a clean 4:3 keeps albums and slideshows visually consistent instead of a jumble of shapes.
Trim, straighten, export
Beyond the locked 4:3 selection, the tool rotates, flips and straightens by up to 45° — so a tilted scan or horizon gets fixed in the same pass as the crop. Everything happens on your device with a live preview, and the export keeps full source resolution inside the cropped area.
Frequently asked questions
- Is my image uploaded to crop it?
- No. Cropping, rounding corners, adding borders, rotating and straightening all run locally in your browser.
- Can I crop an image into a circle?
- Yes. Choose the Circle shape to crop to a circle (or an ellipse on non-square crops). The corners become transparent and the result is exported as a PNG so the circle stays clean on any background.
- Can I round the corners or add a border?
- Yes. Pick Rounded and set the corner radius, and add a border of any thickness and color. A live preview shows the exact result before you download.
- Can I crop to a specific aspect ratio?
- Yes. Choose Free, 1:1, 4:5, 4:3, 3:2, 16:9 or 9:16 and the crop selection snaps to that ratio.
- What format is the cropped image saved in?
- The original format is preserved where possible. Rounded and circle crops export as PNG so their transparent corners are kept (BMP is also saved as PNG).
