Quick steps
How to crop an image
Frame the area to keep
Use a preset or enter the crop position, width and height.
Check the edges
Make sure nothing important is cut off, then save the PNG.
A few useful details
Keep the part of the picture you need
A good crop can make a subject easier to see without changing its proportions. Use it to remove blank scan margins, tidy a product picture or turn a wide photo into a square.
Start with a square, 4:3 or 16:9 preset, then adjust the numbers if needed. The darkened area is the part that will be removed. X is the distance from the left edge, and Y is the distance from the top.
The download is a PNG of the selected rectangle. It cannot include anything beyond the original image. If the cropped copy is still too large for a form, resize or compress that copy next.
Before you save the result
Keep a little space around the subject so faces, products or required document details are not accidentally cut off.
PNG preserves an existing alpha channel, but can be larger than a JPEG photo.
Plan the frame before removing the edges
Use the preset as a starting point
A square, 4:3 or 16:9 preset gives you a centred frame. The subject may not be in the centre, so inspect the preview and adjust X or Y when necessary. A useful crop is about what remains visible, not merely matching a familiar ratio.
Think of X and Y as the starting corner
For a crop starting 100 pixels from the left and 50 from the top, enter X = 100 and Y = 50. The width and height then describe how far the selected rectangle extends from that point. The complete rectangle must fit inside the source.
Leave room around important details
A very tight crop can cut off hair, part of a signature, product edges or required document information. Check all four sides before saving. If the destination will crop again inside a round or square frame, leave enough room for that extra change too.
Resize only after you like the frame
Cropping produces the selected pixels; it does not automatically create the final dimensions requested by another site. Once the framing is right, use Image Resizer for that last size adjustment. Compress afterwards only if the file is still above the allowed KB.
| Setting | Example | Meaning |
|---|---|---|
| X | 100 px | Start 100 pixels from the left |
| Y | 50 px | Start 50 pixels from the top |
| Width × height | 400 × 300 px | Keep that rectangle from the starting corner |

Focus on a smaller area
A tighter crop makes the central subject more prominent. Check that important edges remain in the frame.

EXAMPLE 03
Try a wider composition
A landscape crop removes more from the top and bottom. Cropping changes framing; it does not stretch the subject.

Frequently asked questions
Does cropping stretch the subject?
No. It removes the pixels outside your rectangle instead of stretching the picture into another shape.
Why will the crop settings not fit?
The X and Y position, plus the width and height, must stay inside the original dimensions.
Can I change my mind after cropping?
While the original is selected, change the settings and export again. Keep the original file for later edits too.
Can I extend the crop beyond the picture?
No. This tool selects existing pixels. It does not add new background or generate parts outside the original image.
Will a smaller crop always be a smaller file?
Not necessarily. The crop is exported as PNG, so a cropped photo can still be larger in bytes than its JPEG source.
