Image Cropper

Cropping removes image areas outside a selected frame. It does not resize the remaining pixels, and it keeps the same JPEG, PNG, or WebP format as the source file.

Remove unwanted edges from one image with a freeform frame and pixel width, height, and position.

What This Tool Produces

  • A large crop preview
  • Width, height, and X/Y position in pixels
  • The cropped region at its native pixel size
  • A same-format download

How to Use This Tool

  1. Add one imageChoose a JPEG, PNG, or still WebP file up to 20 MiB.
  2. Frame the cropDrag or resize the frame, or type width, height, and position values.
  3. Crop and downloadCrop image downloads the selected rectangle in the original format.

Controls and Method

Width and height

These are the crop rectangle size in source pixels. The output uses those dimensions without resampling to a different size.

Position X and Y

These are the top-left corner of the crop, measured from the top-left of the source image.

Keyboard position

Focus the crop frame and use arrow keys to move it. Hold Shift for larger steps.

Cropping Is Part of a Sequence

Crop for composition, then resize to the exact pixel dimensions the destination asks for, then compress to hit the file-size limit. Doing it in that order avoids re-encoding the same picture repeatedly.

If the point of the crop is to isolate a subject, removing the background usually gets you closer than a rectangle can. Cropping tightly first gives the model less to misjudge.

Crop Versus Resize

Cropping a 4000 × 3000 photo to a square removes pixels from the left and right. Resizing the whole photo directly to 1000 × 1000 would squeeze a 4:3 scene into 1:1 unless the workflow crops or pads it. Crop when composition should change; resize when the whole scene should remain but use fewer or different pixels.

What This Cropper Does Not Change

  • It does not convert JPEG, PNG, or WebP to another format.
  • It does not resample the selected area to a listed output size.
  • It does not lock the frame to an aspect-ratio preset.
  • Use the Image Resizer when you also need a new width, height, or social-media ratio.

Practical Uses

  • Removing unwanted edges or distractions
  • Reframing a subject off-center
  • Cutting a photo down to a specific pixel box
  • Keeping the source format while discarding unused pixels

Important Limitations

  • Cropping permanently excludes pixels from the output; keep the original.
  • The cropper does not resize the remaining pixels to a different output size.
  • The tool does not remove a subject background or perform content-aware filling.
  • Platform interfaces may crop profile and cover images again on different screens.

Frequently Asked Questions

Does cropping reduce image dimensions?

Yes. Pixels outside the frame are removed, so the download uses the selected width and height.

Can I lock an aspect ratio?

No. This cropper is freeform. Use the Image Resizer when you need a preset ratio such as 1:1 or 16:9.

Can I position a crop without a mouse?

Yes. Focus the visible crop frame and use arrow keys; Shift plus an arrow moves it farther. You can also type Position X and Position Y.

Will cropping make the file smaller?

Often, because fewer pixels are stored, but format, quality, transparency, and image detail also affect file size.

Can the cropper remove a background?

No. It removes rectangular outer areas only; it does not isolate a person or object from its background.
