How to Crop an Image – Step by Step

  1. Upload – click Change Image or drag-and-drop your file. Supports PNG, JPG, JPEG, WebP, AVIF, GIF, SVG, BMP, ICO, TIFF, HEIC, and more.

  2. Choose Aspect Ratio – pick a preset from the dropdown (Instagram, YouTube, Twitter, LinkedIn, etc.). The crop box will lock to that ratio.

  3. Adjust Crop Box – drag the corner handles or move the entire box to frame your subject perfectly.

  4. Fine-tune with Precision Controls – enter exact Width (px), Height (px), X Offset (px), and Y Offset (px) for pixel-perfect cropping. Click Center Crop Box to automatically re-center on your image.

  5. Transform if Needed – use Rotate 90° to rotate clockwise, Flip H to mirror horizontally, or Flip V to mirror vertically.

  6. Preview – see the cropped area in real time on the canvas.

  7. Export – choose your output format:

    • PNG – lossless, supports transparency
    • JPEG – balanced file size for photos
    • WebP – modern web standard (~30% smaller than JPEG)
    • AVIF – next-gen ultra compression
  8. Download – click Export Image to save your cropped image instantly.


Precision Controls for Pixel-Perfect Crops

Our image cropper gives you full numeric control over the crop region:

  • Width (px) – crop box width in pixels
  • Height (px) – crop box height in pixels
  • X Offset (px) – distance from the left edge of the image
  • Y Offset (px) – distance from the top edge of the image

Use these to achieve exact dimensions for banners, thumbnails, or print layouts. The Center Crop Box button resets the crop to the centre of the image with the selected ratio.


Transformations – Rotate & Flip

Apply quick edits before cropping:

  • Rotate 90° – turns the image clockwise by 90 degrees. Useful for orientation fixes.
  • Flip H (Horizontal) – mirrors the image left-to-right (great for selfies or correcting text direction).
  • Flip V (Vertical) – mirrors the image top-to-bottom.

All transformations are applied to the source image before cropping, so you get the exact composition you want.
