Crop image

Drag and resize the crop rectangle directly on your image. Choose an aspect ratio or go free-form. No file leaves your device.

How Crop image works

Image Crop lets you define a rectangular region on your photo using an interactive drag-and-resize overlay, then exports only that region as a new file. The crop preview updates live as you move or resize the selection handles. All Canvas operations run locally; the original file is read from your disk and never transmitted to any server.

You can constrain the crop to a fixed aspect ratio (such as 16:9 for video thumbnails or 1:1 for avatars) or keep it free-form. The pixel coordinates of the selection are displayed so you can enter exact values if you need a precise crop rather than a visual estimate. Output is downloaded directly to your device in the same format as the input, preserving quality where possible.

How to use Crop image, step by step

  1. Drop your image onto the upload area or click to browse.
  2. Drag the corner and edge handles to set the crop region, or type exact pixel coordinates in the fields provided.
  3. Optionally select a fixed aspect ratio to constrain the crop proportions.
  4. Click Crop to apply the selection and generate the cropped image.
  5. Click Download to save the result to your device.

Common use cases

  • A blogger cuts a central subject out of a wide landscape photo to produce a tighter header image for a post.
  • A developer extracts a specific UI element from a full-page screenshot to include in documentation.
  • A product photographer removes distracting background areas from product shots before uploading to a marketplace.
  • An HR professional crops a staff portrait to a consistent square format for an internal directory, without sending personal photos to a cloud service.

Frequently asked questions

Is there any size limit on the image I can crop?

The limit is your browser's memory. Canvas operations on very large files (above 30-40 megapixels) may be slow or may fail on devices with limited RAM. For typical camera photos up to around 24 megapixels the tool handles the operation without issue.

Can I enter exact pixel coordinates for the crop rather than dragging?

Yes. The tool shows the x, y position and the width and height of the current selection as numeric fields. You can type directly into those fields to set a precise crop region, useful when you know the exact pixel boundaries from a design specification.

Does the tool keep any record of the images I open?

No. The image data lives only in the browser tab's memory while the page is open. It is not saved to localStorage, sent to a server, or retained after you close or refresh the tab.

What format is the cropped image exported in?

The output matches the input format where supported. A JPEG input produces a JPEG crop; a PNG input produces a PNG crop with transparency preserved if the original had any.

Can I undo a crop and start over?

Yes. The crop operation generates a new file from the original that was loaded into memory. Clicking reset restores the full original image so you can define a different crop region.

Can I crop a photo on my phone?

Yes. Dragging the crop handles works with touch input on mobile Chrome or Safari the same as with a mouse, though positioning the corner handles precisely is easier on a larger screen. Typing exact pixel coordinates in the fields sidesteps that on a small screen.
