What is Image Cropper?
Cropping removes part of an image rather than scaling it, which is the key difference from resizing. If a photo has too much empty background, an unwanted object at the edge, or the wrong aspect ratio for where you're posting it, cropping fixes the framing without distorting what remains.
This cropper renders the image on an HTML canvas and lets you drag a selection box directly over it. Move and resize the box until it frames exactly what you want, then export just that region as a new file. Nothing is uploaded; the entire crop happens in your browser tab.

Frequently asked questions
Can I crop to an exact pixel size?
Yes. Enter the target width and height in pixels and the tool crops the image to exactly those dimensions. If your target aspect ratio differs from the current image, you choose which part of the image to keep by positioning the crop box.
Can I crop to a specific aspect ratio without knowing the pixel size?
Yes. Enable the aspect ratio lock and enter a ratio like 16:9 or 1:1. The crop box automatically constrains to that ratio. You can then resize the crop box and position it anywhere on the image. The tool calculates the pixel dimensions automatically from the size and position of the box.
Does cropping reduce image quality?
No. Cropping is a lossless operation — it simply removes pixels from the edges without altering the remaining pixels. The quality of the kept portion is identical to the original. File size will be smaller because there are fewer pixels, but quality per pixel is unchanged.
What is the difference between crop and resize?
Crop removes part of the image, changing the framing and reducing the pixel count only by what is removed. Resize changes all pixel dimensions proportionally (or non-proportionally), keeping the full frame visible but at a different resolution. For social media, the typical workflow is crop first to the right ratio, then resize to the required pixel dimensions.
Can I crop a PNG without losing transparency?
Yes. The tool preserves the PNG alpha channel when cropping. If your original PNG has a transparent background, the cropped version will also have a transparent background in the same areas.
How do I crop a circle from a photo?
Standard cropping produces rectangular results. For a circular crop (common for profile photos), use the crop tool to get a square first, then use an image editor or the Image Effects tool to apply a circular mask. Some platforms like Twitter and Instagram automatically display profile photos as circles regardless of the original shape.
Can I undo a crop?
Before downloading, you can adjust the crop box freely. After downloading the cropped image, there is no undo — the removed pixels are gone from the downloaded file. Your original file on your device is never modified, so you can always re-upload the original and crop again.
Does the tool work on mobile?
Yes. The Image Cropper works on any modern smartphone or tablet. Tap the upload area to select an image, drag the handles to set the crop area, and tap Download to save the result to your device.
What is the maximum image size I can crop?
There is no size limit. The tool runs entirely in your browser using the Canvas API — no file is sent to a server. You are limited only by available device memory. Modern browsers handle files up to 50 MB or more without any issue.
Can I crop and resize in one step?
The crop tool focuses on selecting the region and aspect ratio. For a specific output pixel size, crop first to get the right framing, then use the Image Resizer to bring it to exact pixel dimensions. Both tools are free and run entirely in your browser.
