Crop Image

Drag the box over your image to choose the area you want to keep, then download the crop at full resolution.

Processed on your device — nothing is sent anywhere.

How it works

  1. Drop an image onto the upload area or click it to pick a file from your device.
  2. Drag the crop box or its handles to frame the area you want to keep. Choose an aspect ratio preset if you need an exact shape.
  3. Select PNG or JPG and press Download crop to save the cropped image at full resolution.

Frequently asked questions

Is my image uploaded to a server?
No. The image is opened directly in your browser and the crop is cut out on your device. Nothing leaves your computer or phone, so the tool also works offline once the page has loaded.
Does cropping reduce the image quality?
The crop is taken from the original pixels at full resolution, so nothing inside the selected area is resized or resampled. PNG output is lossless; JPG output is re-encoded at high quality, which is usually indistinguishable for photos.
How do I crop to an exact square or 16:9?
Pick one of the aspect ratio presets above the preview — 1:1 for a square, 4:3, 16:9, or 9:16 for vertical video. The crop box then keeps that shape while you move or resize it, and the exact pixel size is shown under the preview.
What aspect ratio should I use for social media?
Use 1:1 for Instagram feed posts and profile pictures, 9:16 for Stories, Reels and TikTok, and 16:9 for YouTube thumbnails and most link preview images. The presets lock the crop box to these shapes, so all you have to do is position the frame.
Can I adjust the crop before saving?
Yes. Nothing is applied until you press Download crop, so you can move the box, resize it from its handles or switch aspect ratio presets as many times as you like. The pixel dimensions of the current selection are shown under the preview, which helps when you need to hit an exact size.

About this tool

This crop tool cuts any rectangular area out of a photo or image directly in your browser. Open a file, drag the crop box over the part you want to keep, and download the result at full resolution. Aspect ratio presets — 1:1, 4:3, 16:9 and 9:16 — lock the box to an exact shape for profile pictures, thumbnails and vertical video, while free mode lets you frame anything.

The image never leaves your device. Your browser opens the file locally, draws it to a canvas, and copies out exactly the pixels inside the crop box when you press Download — there is no upload, no server-side processing and no account. That also means cropping is instant even for large photos, because no time is spent transferring the file anywhere.

Cropping is the fastest fix for the most common photo problems: removing distracting edges, pulling attention onto the subject, turning a landscape shot into a square avatar, or cutting a screenshot down to just the relevant window. Because the output can be PNG (lossless) or JPG (small), the tool fits both design work and quick sharing equally well, and the pixel size readout under the preview makes it easy to confirm the crop meets a platform’s minimum dimensions.

For best results, crop before you resize or compress: cutting away unwanted pixels first means any later compression spends its budget on the part of the image people actually see. And when a platform demands exact dimensions, pick the matching aspect preset here first, then resize the downloaded crop — the shape is already right, so nothing gets stretched or distorted.
