About This Tool
Use 4:3 Image Crop for photos, illustrations, or presentation content that needs a traditional aspect ratio. Move the selection to keep the important part of your original image without stretching the picture to fit.
How to Use
- Choose an image and check the centered 4:3 selection.
- Drag the selection to move it, or drag any corner to resize it. The ratio always stays locked.
- For a precise crop, enter X, Y, and width or height in original image pixels. The other side updates automatically.
- Choose a format and quality where available, click Crop to 4:3, review the preview, and download.
Supported Formats
- Input: JPG/JPEG, PNG, static WebP, and BMP images your browser can open, plus SVG files checked for unsafe content. GIF and animated WebP are not supported.
- Output: PNG, JPG, or WebP if your browser supports it. The original format is used when possible; inputs such as BMP and SVG are saved as PNG when their original format cannot be exported.
Image Processing Notes
- The largest 4:3 area inside the original is centered by default. Dimensions are rounded to whole pixels and kept within the image edges.
- A 1920×1080 image starts with a 1440×1080 crop at X=240, Y=0. A 1600×1200 image is already 4:3 and can keep all its content.
- At the same height, 4:3 is narrower than 16:9. Choose the ratio that suits your subject and intended layout.
- Output dimensions match the selection in original image pixels. No padding is added and the selected content is not stretched.
- PNG and WebP can preserve transparency. JPG blends transparent and partially transparent areas with your selected background color, which is white by default. The checkerboard appears only in the preview.
- Downloaded images usually do not retain the original EXIF, GPS, or other metadata. Phone photos are corrected using their EXIF orientation before dimensions are calculated and the image is processed.
Bitmap files can be up to 100 MiB; files over 50 MiB trigger a high-memory-use notice. Original and output images are limited to 40 million pixels, with each side no longer than 16,384 pixels. SVG files must use UTF-8 and be no larger than 2 MiB.

FAQ
What does a 4:3 aspect ratio mean?
The width is 4÷3 times the height, or about 1.3333. Common sizes include 1600×1200, 1440×1080, and 800×600.
Is 1600×1200 a 4:3 size?
Yes. Dividing both dimensions by 400 gives 4 and 3, so the entire picture can be kept without changing its proportions.
How is 4:3 different from 16:9?
At the same height, 16:9 is wider and 4:3 is closer to a square. Cropping the same image at each ratio may keep different content along the sides or top and bottom.
Are my images uploaded to a server?
No. Opening, previewing, processing, and downloading your image all happen in your current browser. Your image is never uploaded or sent to an online image processing service.
