Detailed User Guide

Step 1: Upload Your Image

Upload a JPG, PNG, or WebP image. The full image appears in the workspace with a dashed crop overlay.

Step 2: Adjust the Crop Area

You can interact with the crop overlay in two ways:

  • Move: Click and drag anywhere inside the dashed overlay to reposition it over your desired area
  • Resize: Drag the corner handles (small circles at each corner) to adjust the crop dimensions
  • Aspect ratio presets: Use the dropdown to lock to common ratios like 1:1 (Instagram), 16:9 (widescreen), or 9:16 (Stories)
Tip: When a preset ratio is selected, resizing one corner automatically adjusts the other dimension to maintain the ratio.

Step 3: Crop & Download

Click "Crop" to apply. The image is cropped to your selection and the overlay disappears. Click "Download" to save as a PNG.

Best Use Cases

  • Social media cropping — Use preset ratios to match platform requirements exactly
  • Photo framing — Remove unwanted edges or improve composition (rule of thirds)
  • Thumbnail creation — Crop to the most visually interesting part of an image
  • Uniform image sets — Apply the same aspect ratio to a series of photos for consistency

Pro Tips

  • Cropping never reduces the quality of the remaining pixels — it simply removes unwanted areas
  • For portraits, place the subject's eyes along the top third line for pleasing composition
  • The 1:1 preset is perfect for Instagram posts; 9:16 for Stories and Reels
  • After cropping, you can use the Resizer tool to adjust to exact pixel dimensions

常见问题

Use the preset ratios: 1:1 for Instagram posts, 9:16 for Stories/Reels, 16:9 for Twitter/X headers.
No. Cropping simply removes pixels. The remaining area retains the original resolution and quality.
