Drop multiple images to combine them into one PDF, Word document, or PowerPoint presentation — or convert each image separately.

Drop an image and pick an aspect ratio. The crop is center-aligned so the subject stays in frame. Combined with resize, you can hit an exact pixel size and aspect in one step.

Cropping to a shape, not a size

Cropping to an aspect ratio trims the image to a proportion — square, 4:3, 16:9 — by removing equal amounts from opposite edges. It changes the shape of the frame without stretching anything inside it, which is the important difference from resizing.

This is what most platform requirements actually ask for. A square profile photo, a 16:9 video thumbnail, a 4:5 social post: these are shapes. Feeding a rectangular photo into a square slot without cropping produces either letterboxing or an automatic centre crop you did not choose.

Common shapes and where they are used
RatioTypical use
1:1Profile pictures, avatars, product thumbnails.
4:3Presentations, older displays, many documents.
16:9Video thumbnails, slides, banners.
3:2Standard photography, most print sizes.

Crop first, then resize and compress

Order matters. Cropping removes pixels you do not want, so doing it first means everything afterwards works on less data — the resize is cleaner and the compression has less to encode.

Cropping is destructive: the removed edges are gone from the output. Keep the original if you might need a different shape later, which is more common than people expect once the same photo is needed for several platforms.

Frequently asked questions

  • Can I pick a custom aspect ratio?+

    The crop tool offers common ratios: 1:1, 4:3, 16:9, 3:2, and 9:16. For a freeform crop, set both width and height with aspect ratio lock off.

  • Is the crop centered?+

    Yes. The crop box is centered on the image so the subject in the middle stays in frame.

  • Can I crop and resize at the same time?+

    Yes. Set both a resize dimension and a crop aspect ratio in the same conversion.
