Crop Image Online – Square, 4:3, 16:9 and Passport Ratios

How to crop an image

1. Add a photo — choose a file, drop it, or paste a screenshot.
2. Pick an aspect ratio, such as Square 1:1 or 16:9.
3. Drag the photo to position it and use the zoom slider (or pinch on your phone).
4. Rotate with the arrow buttons if the photo is sideways.
5. Choose the format and tap Crop image, then download the result.

Common aspect ratios

Example

A wide 1,600 × 900 photo cropped to Square 1:1 gives a 900 × 900 image — the largest square that fits. Zoom in to crop tighter around the subject; the output then becomes smaller in pixels but keeps full detail.

Tips for better crops

• Rule of thirds. Turn on the grid in your mind: placing the subject along the third lines often looks better than dead centre.
• Leave some space around faces and products — very tight crops can look cramped.
• Crop before compressing. Removing unwanted areas first makes the image compressor more effective.
• For an exact pixel size, crop to the right ratio here, then use the image resizer.

Cropping or resizing — which do you need?

• Cropping cuts away the edges to change what’s in the picture and its shape. The pixels you keep stay at full quality.
• Resizing keeps the whole picture but changes how many pixels it has, making it bigger or smaller.

Many tasks need both: crop to the right shape here, then set the exact size with the image resizer. For example, a profile photo that must be 400 × 400 pixels: crop to Square 1:1, then resize to 400 pixels wide.

Who uses an image cropper

• Social media users preparing posts, stories and profile pictures.
• Online sellers making consistent square product photos.
• Students trimming scanned pages and screenshots for assignments.
• Applicants cropping photos to passport shape — or use the passport size photo maker for print sheets.
