How Image Crop works

  1. Upload an image by clicking the upload area or dragging it in.
  2. Choose an aspect ratio preset (1:1, 16:9, 4:3, 3:2) or select 'Custom' to enter your own dimensions.
  3. Enter the crop region's X, Y position and width/height in pixels.
  4. Check the live preview to confirm the crop area looks correct.
  5. Click Crop, then download the result as a PNG.
  • Crop a wide photo down to a square for a profile picture or avatar.
  • Trim a screenshot to remove browser chrome or unwanted edges.
  • Cut a 16:9 thumbnail out of a larger image for a video platform.
  • Isolate a specific region of a diagram or scanned document for sharing.
  • Standardize a batch of images to the same crop dimensions for a gallery.

Cropping is performed locally on a canvas element in your browser. Your image is never uploaded to any server.

  • Cropping uses numeric coordinate input rather than interactive drag-to-select.
  • Output is always PNG — there's no option yet to export cropped results as JPG.
  • Coordinates must be entered manually, so you may need to check the source image's dimensions first.

Image Crop

Image Crop lets you define a crop region by entering pixel coordinates, or choose a common aspect ratio preset (1:1, 16:9, 4:3, 3:2). Preview the result before downloading — all in the browser, no server involved.

FAQ

Frequently asked questions

Can I crop by dragging on the image?

The current version uses coordinate input fields and aspect ratio presets rather than mouse dragging. Drag-to-crop is planned for a future update.

Will the crop degrade image quality?

No — cropping just selects a region of the original pixels; it does not re-encode, blur, or resample the image content inside the crop.

How do aspect ratio presets work?

Selecting a preset like 1:1 or 16:9 constrains the crop region to that ratio, so you only need to position and size it — useful for profile pictures (1:1) or video thumbnails (16:9).

What coordinates do I enter?

Enter the X and Y position of the crop's top-left corner, plus a width and height, all in pixels relative to the original image's dimensions.

What output format does the cropped image use?

The cropped result is downloaded as PNG, which preserves transparency and avoids additional compression artifacts.

Can I crop the same image multiple times?

Yes. After downloading one crop, you can adjust the coordinates or aspect ratio and crop the same source image again without re-uploading.

Does the preview match the final downloaded image exactly?

Yes. The preview is rendered from the same canvas operation used to generate the downloadable PNG, so what you see is what you get.
