Image Cropper

Cuts a region out of an image — drag a box with the mouse, type exact coordinates, or lock a ratio like 1:1 or 16:9 and fit the box inside it. The cropped area is saved as a new image, processed entirely in your browser.

How to use

1. Drop the image; it appears in the editor.
2. Drag to select the region, or enter coordinates for pixel-exact bounds.
3. Lock an aspect ratio first if the output must be square or widescreen.
4. Download the cropped image.

When you actually need this

• Cutting a square avatar out of a wider photo.
• Trimming a screenshot to just the window or error message that matters.
• Removing a bystander or clutter at the frame's edge.
• Matching a platform's ratio — 16:9 for a thumbnail, 4:5 for a feed post.

Crop is subtraction, and it is permanent in the copy

Everything outside the box is discarded in the output — the pixels inside are untouched, so there is no quality loss, but the discarded area is gone from that file. Keep the original if you may want a different framing later. Cropping to a ratio changes shape by removing content; resizing changes size by scaling it — a portrait photo forced to 16:9 by cropping loses its top and bottom, while resizing it would squash it instead. For screenshots with sensitive corners, crop rather than blur when the information simply should not ship at all.

FAQ

Are my photos uploaded to a server when I use Image Cropper?

No. Image Cropper reads the file with the browser's Canvas API and processes every pixel on your own device. The image never leaves your computer, which is why it still works if you go offline after loading the page.

Will Image Cropper reduce the quality of my image?

That depends on the setting you choose. JPEG and WebP are lossy, so a lower quality value means a smaller file and more visible artifacts; PNG is lossless and keeps every pixel exactly. Start around 80 percent quality — most photos stay visually identical at roughly a third of the original size.

Is there a file size or count limit?

There is no limit imposed by the site, because nothing is uploaded. The practical ceiling is your device's memory — very large files (over roughly 50 MP) may be slow on an older phone.
