Image Crop Tool
Define the rectangle to keep in pixel coordinates from the top-left of your image. Download a PNG of the cropped region.

Works in modern desktop and mobile browsers. Focus this area (tap or Tab) before pasting.
About this tool
This is a precision cropper for people who know the pixels they need—useful after taking a fixed screenshot or when matching a design spec. For creative freehand cropping, adjust numbers while watching your preview image below.
Tips
- Keep crop inside image bounds
- PNG output keeps edges sharp
- Combine with resizer if you need scale too
Input
- Drag & drop, paste, or browse
- Natural size loads automatically
- Export clamps region to image edges
How it works
- Add an image.
- Set X, Y, width, height (pixels from top-left).
- Download cropped PNG.
FAQ
Why numeric crop instead of dragging handles?
Exact numbers reproduce the same crop across batches and match specs (“take 1200×630 from x=0 y=100”). Visual drag UIs are friendlier for one-offs but harder to document; this layout favors engineers, marketers with rigid templates, and screenshot pipelines.
What coordinate system do you use?
Origin (0,0) is the top-left pixel of the decoded bitmap, matching CSS `object-position` math and most image editors. Width and height extend right and down. Values outside the image are clamped at export so you never get partially empty output.
Does crop change resolution or DPI metadata?
Output pixel dimensions equal your width×height fields (after clamping). Embedded DPI/EXIF from the source is not carried into the new PNG—this is a fresh raster. For print, set physical size in your layout tool using the known pixel count.
Can I crop rotated photos?
Only axis-aligned rectangles on the bitmap as decoded. Rotate or deskew in an editor first if the horizon is tilted; otherwise you will include empty wedge areas or cut off content unintentionally.
Why PNG only?
PNG avoids another lossy JPEG generation cycle after you already picked exact pixels. If you need JPEG for size, run the crop output through the Image Compressor and choose JPEG there.
Paste from Snipping Tool / Share sheet?
Yes: focus the dashed drop zone, then paste. Many OS screenshot utilities put a bitmap on the clipboard; we take the first image item. If paste does nothing, save to disk and browse—the clipboard path varies by app.
