Quick answer
To crop an image, drag the selection box over the part you want to keep, resize it with the corner handle, and download. This tool crops entirely in your browser using the HTML canvas, so your photo is never uploaded. You can crop freely or lock the box to a fixed aspect ratio such as 1:1 (square), 4:3, 3:2, or 16:9, which is handy for profile pictures and thumbnails.
Formula & method
The selection box is stored as fractions of the displayed image, so it stays accurate no matter how the image is scaled to fit your screen. On download, those fractions are multiplied by the image's true pixel dimensions and the chosen region is drawn to a canvas at full resolution and exported as a PNG — so the crop keeps the original quality.

When to use this tool
- Making a square avatar or a 16:9 thumbnail.
- Trimming whitespace, borders, or unwanted edges from a photo.
- Isolating one detail or subject from a larger image.
Common mistakes
- Expecting cropping to add pixels — it only removes them, so you can't crop in and keep the original width.
- Cropping a low-resolution image tightly, which makes the result look pixelated when enlarged.
- Forgetting to lock the aspect ratio before cropping for a platform that needs an exact shape.
Frequently asked questions
How do I crop an image here?
Upload it, drag the box to position it, drag the corner handle to resize, then click Crop image and download. Everything happens in your browser.
Is my photo uploaded anywhere?
No. The crop is done locally with the HTML canvas, so the image never leaves your device.
Can I crop to an exact aspect ratio?
Yes. Choose 1:1, 4:3, 3:2, or 16:9 and the box locks to that ratio as you resize; pick Free for any shape.
Does cropping reduce quality?
No. The kept region is exported at the original pixel resolution, so it's as sharp as the source — it just has fewer total pixels.
What format is the download?
A PNG, which is lossless and preserves transparency. Use a converter afterwards if you need JPG or WebP.
Can I use it on my phone?
Yes — the box supports touch, so you can drag and resize on mobile.
