An image cropper with pixel precision
Cropping removes distracting edges, straightens composition and fits images into the shape a layout needs. This image cropper lets you draw the crop area directly on the picture, lock it to a common aspect ratio, and fine-tune the position and size in exact pixels. The crop is applied to the full-resolution image, so you do not lose quality beyond what you cut away.
Aspect ratio presets
| Ratio | Typical use |
|---|---|
| 1:1 | Profile pictures, Instagram posts, product thumbnails |
| 4:3 / 3:4 | Classic photos, presentations, tablets |
| 3:2 / 2:3 | DSLR photos and prints (e.g. 6×4 inches) |
| 16:9 / 9:16 | Video thumbnails, banners, stories and reels |
| Free | Any shape, e.g. cutting a region out of a screenshot |
When you pick a ratio, the current selection is adjusted to fit it and stays locked while you resize.
Precise control
The selection shows the area that will be kept while the rest of the image is dimmed. Drag inside to move it, drag the eight handles to resize, or type values in the X, Y, Width and Height fields. Select all resets the selection to the full image. The line under the controls shows the original and the output size in pixels.
Output format
The format defaults to the input format. Choose PNG for screenshots and graphics, JPG for photos and WEBP for the smallest web files; the quality field applies to JPG and WEBP. To reduce file size further, run the result through the image compressor, and to change dimensions without cropping use the image resizer.
Cropping for social media
Each platform crops images differently in feeds and previews. Square (1:1) works almost everywhere, 4:5 portrait takes up more space in mobile feeds, 16:9 suits video thumbnails and link previews use roughly 1.91:1. Cropping yourself instead of letting the platform do it keeps important content — faces, text, products — inside the visible area. After cropping, check the pixel dimensions in the output line and, if needed, scale the result to the platform's recommended size.
Common cropping mistakes
- Cropping too tight for round avatars. Many sites show profile pictures in a circle, which hides the corners of your square. Leave space around the face so the circle does not cut off hair or chin.
- Enlarging a small crop. A 300 × 300 area taken from a large photo stays 300 × 300 pixels. Scaling it up afterwards makes it blurry, so check the output size line before you download and start from a larger selection if you can.
- Saving screenshots as JPG. Text and sharp interface edges get fuzzy halos in JPG. Keep screenshots in PNG, and use JPG or WEBP for photos.
- Letting a platform crop again. If a site crops uploads to its own ratio, pick that ratio here so nothing important ends up outside the visible area.
To crop a batch of images to the same size, note the X, Y, Width and Height values from the first one and type them for the others.
