Image Cropper

This image cropper cuts a photo down to the part you want, in any shape or exact pixel size, right in your browser. Use it for profile pictures, product shots, thumbnails and social posts.

You drag a box over the picture or type the numbers. Lock a ratio such as 1:1, 4:5 or 16:9, or pick a social size and the output width is filled in for you. You can also rotate, flip and straighten a crooked horizon before you cut.

Nothing is uploaded. The photo is read and cropped on your own device, phone pictures are turned upright first, and there is no watermark or sign-up.

Cropping removes pixels from the edges. It does not blur the ones you keep. A 4032×3024 phone photo (12 MP) cropped to a square becomes 3024×3024, about 9.1 MP, and every remaining pixel is the same as before.

Two things can make it look worse. Saving as JPG or WebP compresses the image again, though quality 90 hides that well. And if you crop a small area and scale it up, the browser has to invent pixels, so the picture goes soft.

Aspect ratio is the shape of the picture, written as width to height. Pick it based on where the image will be shown, then crop. These are common targets:

• 1:1 square: profile pictures, product listings, Instagram grid posts
• 4:5 portrait (1080×1350): the tallest feed post Instagram shows without cutting
• 9:16 vertical (1080×1920): Stories, Reels, TikTok and phone wallpapers
• 16:9 wide (1280×720 or 1920×1080): YouTube thumbnails, slides and video frames
• 3:2: the native shape of most DSLR and mirrorless cameras, and 6×4 inch prints

Turn on the rule-of-thirds grid and move the Straighten slider until a line that should be level, such as a horizon or a table edge, runs parallel to the grid. The sample photo opens tilted by 4°, so try +4° on it.

Rotating a rectangle leaves four empty triangles at the corners. Zoom to hide empty corners enlarges the picture just enough to cover them. A 5° fix on a 3:2 photo needs about 13% more, so you lose a little at the edges. Untick it to keep every pixel; the corners then turn transparent in PNG or white in JPG.

There are two ways, and you can combine them. To cut an exact area, type the X and Y position and the width and height of the box. The boxes update as you drag, so you can drag roughly and then fix the numbers.

To get an exact output size, lock the ratio first, for example 16:9, then tick Resize the output and enter the width, such as 1280. The height follows from the ratio, so you end up with exactly 1280×720 whatever the size of the box.
