About this tool
Cropping is how you fit one image to many places: a square for a profile picture, 16:9 for a video thumbnail, 9:16 for a story, 4:5 for a social feed. The tool's job is to make the frame land where the subject is.
Rather than asking you to drag a box, this cropper asks for the shape and the anchor. Choose 1:1 and Centre to pull a square out of the middle of a photo, or 16:9 and Top to keep the sky while trimming the foreground. The inset control trims a margin from every edge first, which is useful when the outer few percent of an image is unwanted.
Features
- Six crop shapes including 1:1, 16:9, 4:3, 4:5 and 9:16
- Five anchoring positions so the subject stays in frame
- Adjustable inset from every edge at once
- The exact crop rectangle is reported in pixels
- Output to JPEG, PNG or WebP
- Transparency preserved when cropping PNG or WebP
Frequently asked questions
Can I crop to a specific pixel size?
Set the crop shape to Free, choose the anchor, and then resize the result with the image resizer. Cropping controls the shape and the framing; resizing controls the dimensions.
What does the inset do?
It shrinks the available area by a percentage from every edge before the crop is calculated, which effectively trims a border from the image. It is useful for scans with a dark margin or screenshots with a window chrome edge.
Will cropping reduce the file size?
Yes, proportionally to the number of pixels removed, though the reduction is not always exactly linear because of how compression works on the remaining content.
Can I crop several images to the same shape?
Run them one at a time; each keeps its own settings, so you can reuse the same shape and anchor for a consistent batch.
