Crop an image to 4:3

Where the 4:3 ratio fits

4:3 was the standard of compact cameras, phone cameras in their default mode, and the old 4:3 displays and slides. It still shows up anywhere that wants a gently wide frame rather than a dramatic widescreen one, and it crops most phone photos with very little loss since many are already close to 4:3.

It is also the shape of a classic presentation slide. If you are building a 4:3 deck rather than a modern widescreen one, cropping images to 4:3 makes them fill each slide without gaps.

4:3 versus 3:2 and 16:9

The three wide ratios serve different looks. 4:3 is the most square-ish and balanced, 3:2 is the slightly wider photographic and print ratio, and 16:9 is the dramatic widescreen of video. Pick by destination: a 4x6 print wants 3:2, a video wants 16:9, and a general photo or older slide suits 4:3.

Because they are close, switching ratios changes the crop only a little at the edges, so it is worth trying the one that matches where the image will actually be used.

Crop, then size for the destination

Crop to 4:3 here to set the shape, then resize in pixels for the exact dimensions a slide or frame needs. The crop keeps the original quality inside the selection, so the kept area stays sharp.

It all runs in your browser, with nothing uploaded. Frame to 4:3, download, and use it wherever a classic ratio fits.
