Crop an image

This image cropper lets you cut a photo down to the part you want, freely or locked to a ratio like 1:1, 4:5 or 16:9, and download the result. Drag the frame with a mouse or a finger, or type exact pixel values. It runs entirely in your browser: the photo is opened on your device and never uploaded.

How to use it

1. Choose an image above, or drop it in on a computer.
2. Move and resize the frame over the part you want to keep, or pick a ratio first.
3. Download the cropped copy. Your original file is not changed.

Framing the crop

• Move: drag inside the frame.
• Resize: drag any of the four corner handles. With a ratio selected, the frame keeps its shape.
• Fine adjustments: click or tap the frame and use the arrow keys to move it 1 pixel at a time, or 10 pixels with Shift held down.
• Start over: Reset puts the frame back to the full image.

The handles are large enough to grab with a thumb, and the frame follows touch without scrolling the page, so cropping on a phone works as well as with a mouse.

Aspect ratios

A ratio describes shape, not size. A 1:1 crop from a 12 MP photo can be 3000 × 3000 pixels. If a platform asks for a precise size, crop to its ratio here, then set the exact width in the image resizer.

Exact pixels

Under the image there are four fields: X and Y for the top-left corner of the crop, Width and Height for its size. All of them are in the original image's pixels, not screen pixels, so what you type is what you get in the file. The fields update as you drag, and the frame follows when you type. That makes it easy to crop several screenshots to exactly the same area, or to cut a scan to the edges of a document.

Quality, format and metadata

Cropping keeps the pixels you select 1:1: nothing is scaled up or down. The copy is then saved in the same format as the original, or in JPEG, PNG or WebP if you choose. JPEG and WebP use a quality of 92 by default; PNG is lossless.

Like every image tool on this site, the cropped file is saved from the pixels alone, so location, date and camera metadata are left behind. If the photo is only meant to get lighter, the image compressor can bring it under a size limit afterwards, and the EXIF remover strips metadata without cropping anything.

When the full photo should stay private

Often the uncropped original is the sensitive one. You crop the address off a delivery photo, the face off a skin condition you're sending to a doctor, the other pages off an ID scan. The cropped copy goes out; the complete original stays in the Camera Roll, synced and easy to stumble on.

sigil. gives those originals a separate place. Everything inside is encrypted on your phone with a 256-bit key that only your sign unlocks, and nobody, including us, has a copy of that key. It's built for exactly this kind of material: medical photos, ID documents, work papers. Photos taken with its private camera never appear in the Camera Roll at all.
