How to use this tool

Starts with a locked portrait frame that is three units wide for every four units high, so the visible area can be repositioned without changing its proportions.

  1. 1Select an image from your device.
  2. 2Position the locked 3:4 crop frame around the subject.
  3. 3Apply the crop and download the result.

Best for

Portrait compositions that need a moderate vertical frame rather than a square or a taller 4:5 crop.

How a 3:4 portrait crop is measured

A 3:4 frame is three units wide by four units high. It is portrait-oriented and slightly narrower in proportion than a 4:5 frame, while still being taller than it is wide.

Keep the subject inside the portrait frame

The locked frame changes the visible composition when the source has different proportions. A landscape source may lose its outer sides; a taller source may lose some content above or below. Cropping does not add padding, and resizing is a separate step if you need exact output pixels.

Limitations

  • A source with a different shape loses pixels outside the selected 3:4 frame; the tool does not stretch the image to fit.

Questions

Is 3:4 a portrait aspect ratio?

Yes. Three units of width by four units of height makes the image taller than it is wide.

What pixel sizes are 3:4?

600 × 800, 900 × 1200, and 1200 × 1600 are examples. Many other dimensions preserve 3:4 when both sides scale equally.

How is 3:4 different from 4:5?

Both are portrait shapes, but 3:4 is proportionally narrower. For example, 600 × 800 is 3:4 and 800 × 1000 is 4:5.

Does a 3:4 crop stretch the source image?

No. It keeps a 3:4 area and removes what falls outside that frame rather than stretching the image.

Will cropping to 3:4 set the final pixel width and height?

The crop uses pixels from the selected source area, so it does not promise fixed output dimensions. Use the resize tool afterward for exact pixel dimensions.

Is this 3:4 crop processed on a server?

No. Your image is decoded, cropped, and exported locally in your browser.
