Crop image online

Drop a photo and the crop frame is already there. Drag it over the part you want to keep, lock an aspect ratio if you need one, and download the result.

How it works

  1. Drop your image — the Crop tool opens with a frame over most of the picture.
  2. Drag the edges, corners or the whole frame, or choose a ratio such as 1:1 or 16:9.
  3. Press Enter or Apply crop, then click Export to download.

Choosing the right aspect ratio

Freeform lets you crop to any shape, which is fine for tidying up a snapshot. When the picture has a destination, lock a ratio instead. 1:1 suits profile pictures and square posts, 16:9 fits video thumbnails, slides and desktop wallpapers, and 9:16 is the vertical format of stories and phone screens. 3:2 matches most camera sensors and standard photo prints, while 4:3 and 3:4 fit tablets and many phone photos. The frame keeps its ratio while you resize it, so all you decide is what goes in.

Composing with the rule-of-thirds guides

The crop frame shows two horizontal and two vertical lines that split it into nine parts. Placing the main subject — an eye, a person, the horizon — on one of those lines or where two of them cross usually looks more balanced than putting it dead center. Leave a little space in the direction a person is looking or moving. If the horizon is tilted, rotate the photo a few degrees with the Transform tool first, then crop, so the same frame also cuts away the empty corners.

Cropping to an exact area

If you already know exactly which part you need — one product from a group shot, a single face from a crowd, a paragraph from a screenshot — draw a box around it with Rectangle select and choose Crop to selection in the Image menu. Cropping in the editor can always be undone, so experiment freely; the cut only becomes permanent in the file you export. Save photos as JPEG, and screenshots or graphics with sharp edges and text as PNG.

Frequently asked questions

Does cropping reduce image quality?

Cropping itself only removes pixels; the ones you keep are unchanged. Quality can drop slightly when you save, because JPEG and WebP are lossy formats. Export photos at a quality of 85–92, or choose PNG when you need a lossless copy.

How do I crop a picture to a square?

Choose 1:1 in the ratio presets of the Crop tool. The frame becomes a square that stays square while you resize it; drag it over the area you want and press Enter. Export, and the image is ready for a profile picture or a square post.

Can I crop a photo on my phone?

Yes. The editor works in mobile browsers: drag the corners of the frame with your finger and pinch to zoom for precise placement. The photo is processed on the phone itself and is not sent to any server.

Can I undo a crop?

Yes, as long as you are still in the editor. Press Ctrl/⌘+Z to step back; the history keeps up to 80 steps, fewer on large photos, where memory sets the limit. The exported file contains only the cropped area, while the original file on your device stays exactly as it was.
