About Crop Image
Cropping removes the outer parts of an image to keep only the rectangular region you want, changing the composition and the dimensions without altering the pixels you keep. This tool loads your image into the browser and lets you drag a selection box directly over it: drag inside the box to move it, drag the corner or edge handles to resize it, or draw a fresh rectangle anywhere on the image. A rule-of-thirds grid overlays the selection to help you line up subjects along the classic composition guides, and the live pixel dimensions of the selection are shown as you adjust it.
When you confirm the crop, the tool maps your on-screen selection back to the image's true resolution and renders just that region onto a canvas, so the output keeps full quality for the area you kept — cropping a 4000-pixel-wide photo to its center still produces a full-resolution result, not a scaled-down one. The output format depends on the input: PNG images stay PNG and keep any transparency, while other formats are exported as JPEG at 92% quality. The original file you started with is never modified; you download a new cropped copy.
Cropping is one of the most common everyday edits: straightening up a screenshot to remove window chrome, cutting a subject out of a busy background, trimming a photo to fit a banner or thumbnail slot, removing unwanted edges, or focusing attention on the important part of a picture. A practical tip is to crop before you resize — crop first to choose the composition and dimensions you want, then resize the result to the exact pixel width a platform requires.
This crop tool is free-form, meaning you can draw any rectangle; it does not yet lock to fixed aspect ratios such as 1:1 or 16:9, so for a perfectly square avatar you would size the box by eye using the live dimension readout. It handles one image at a time. All of the work happens on a canvas in your browser — the image is read locally, cropped on your device, and never uploaded, which keeps personal screenshots and photos private.
Frequently Asked Questions
- How do I select the area to crop?
- Drag a selection box directly on the image. Drag inside the box to move it, drag any corner or edge handle to resize it, or click and drag on an empty area to draw a new rectangle. A rule-of-thirds grid and a live pixel-dimension readout help you frame the crop precisely.
- Does cropping reduce the quality of the part I keep?
- No. The selection is mapped back to the image's full native resolution before the crop is rendered, so the region you keep retains its original detail. Cropping the center of a high-resolution photo still gives you a full-resolution result rather than a scaled-down one.
- Can I crop to a fixed aspect ratio like 1:1 or 16:9?
- The crop is currently free-form, so you can draw any rectangle but it does not snap to a locked ratio. To approximate a specific shape, watch the live width-by-height readout as you drag the handles. For an exact square or banner, you can also crop freely and then resize the result.
- Which formats can I crop, and what comes out?
- JPEG, PNG, and WebP inputs are supported. PNG images stay as PNG and keep any transparency, while other formats are exported as JPEG at 92% quality. The output is always a raster image — a new cropped copy, leaving your original untouched.
- Should I crop or resize first?
- Crop first, then resize. Cropping chooses the composition and removes the parts you don't want, which also changes the dimensions; resizing afterward scales that cropped result to the exact pixel width a platform or layout requires. Doing it in this order avoids resizing pixels you were going to throw away anyway.
- What does the rule-of-thirds grid do?
- It overlays two evenly spaced horizontal and vertical lines on your selection, dividing it into nine equal parts. Placing key subjects along those lines or at their intersections is a classic composition guideline that tends to produce more balanced, visually pleasing crops. It is purely a visual aid and does not constrain where you can crop.
- Can I crop several images at once?
- The tool works on one image at a time: load an image, set the crop region, and download the result. For multiple images, repeat the process for each one. Each crop is independent.
- Is my image uploaded when I crop it?
- No. The image is loaded and cropped entirely on a canvas in your browser, so it stays on your own device and is never sent to a server — which matters for screenshots or personal photos you would rather not share.
