How to use it
- 1.Drop an image on the page, paste it from the clipboard, or click “Choose an image”.
- 2.Pick an aspect ratio such as 1:1 or 16:9, or keep Free. Drag the box to move it and its handles to resize it, or type exact pixel values into X, Y, Width and Height.
- 3.Rotate or flip the image if needed. The crop box turns with it.
- 4.Choose the format and click Download. To hand the result to another tool, use the links under the button.
Which aspect ratio to use
1:1 is the square used for profile pictures, avatars and app icons, and still the classic Instagram post. 4:5 is the tallest portrait Instagram shows in the feed, so it takes up the most screen space.
16:9 matches widescreen monitors, TVs and video: YouTube thumbnails (1280 × 720), presentation slides and website hero images. 9:16 is the same shape turned upright for Stories, Reels, TikTok and Shorts.
3:2 is the shape of most camera sensors and of 10 × 15 cm (4 × 6 in) prints. 4:3 is the usual shape of phone photos and tablet screens. Use Original to keep the image’s own proportions, and the swap button next to the ratios to switch between landscape and portrait.
Cropping to exact pixels
The X, Y, Width and Height fields use real pixels of the image, counted from its top-left corner, so a 1080 × 1080 crop gives exactly 1080 × 1080 pixels. With a ratio selected, changing the width changes the height to match.
A crop can only take away pixels. If you need a set size that’s bigger or smaller than the crop, crop to the right shape first (for example 16:9), then scale it with the image resizer to 1280 × 720 or whatever the site asks for.
Rotating, flipping and phone photos
Rotate left and right turn the image by 90 degrees; flip mirrors it, which is useful for selfies that come out reversed. Several turns and flips can be combined, and Reset brings back the untouched image.
Phones often save photos sideways with a note (the EXIF orientation tag) telling viewers how to turn them. This tool applies that note before you crop, so the image appears and downloads the right way up. The saved file doesn’t keep the camera metadata (EXIF), including any GPS location.
Questions and answers
Is my image uploaded?
No. The image is opened, cropped and saved by your browser on your own device. Nothing is sent to nestoo or anyone else, and the tool keeps working offline once the page has loaded.
Does cropping reduce image quality?
Cropping itself only removes pixels; the rest stay exactly as they were. Quality can only change when the result is saved in a lossy format: JPG, WebP and AVIF at a lower quality setting. Saving as PNG is lossless, and JPG at quality 90 or above looks the same as the original.
How do I crop an image to an exact size like 1080 × 1080?
Choose the 1:1 ratio and type 1080 into Width. If the image is smaller than 1080 pixels on its shortest side, crop it to 1:1 at full size and enlarge it with the image resizer instead.
Can I crop an image into a circle?
Not with this tool: it crops rectangles. For a round profile picture, crop to 1:1; Facebook, Instagram, LinkedIn, Slack and most other sites show square photos as circles by themselves.
How do I rotate an image without cropping it?
Leave the crop box covering the whole image (it does when you open one, or after Reset), use the rotate or flip buttons, and download. The full picture is saved, turned the way you chose.
