Crop Images Online — Free Image Cropper

LeanImg crops images directly in your browser using the Canvas API. Select your image, draw a crop rectangle or choose an aspect ratio preset, and click Crop. Your image is processed instantly on your device — nothing is uploaded to any server. Download the result with one click.

LeanImg supports cropping JPG, PNG, WebP, AVIF, and GIF images. Your cropped image is saved in the same format as the original, preserving quality. LeanImg is one of the few online croppers that supports modern formats like WebP and AVIF.

LeanImg processes images entirely in your browser. Your files never leave your device — nothing is uploaded to any server. No data is stored or shared. This makes it one of the safest ways to crop personal photos, documents, or sensitive images online.

Select your image in LeanImg, then choose from preset aspect ratios: 1:1 (square), 4:3, 3:2, 16:9, 9:16, and more. The crop rectangle locks to your chosen ratio. Drag to position the crop area, then click Crop and download. Free, instant, no sign-up.

LeanImg supports images up to 10 MB in size. Since all processing happens in your browser, there are no server-side limits. For best performance on mobile devices, we recommend images under 5 MB. There is no sign-up and no watermark on your cropped image.

It depends on the format. A PNG crop is lossless: the pixels inside your rectangle come out byte-identical. Every other format is decoded and re-encoded at quality 92, which is high enough to be invisible on a photograph but is still a second lossy generation. If the image is a screenshot full of small text, check the result at 100% before you use it. That single check catches the only case where a crop costs you anything visible.

Because quality 92 is often a higher setting than your source was saved at, so the file grows even though pixels were removed. A real run makes this obvious: a 3840x2160 photo at 538.6 KB, cropped to 16:9, keeps all 3840x2160 pixels because the source is already 16:9, and comes back at 671 KB. That is 25% bigger for a crop that removed nothing. If the file has to be small, run the result through the image compressor afterwards.

Cropping removes pixels from the edges and changes the framing. Resizing keeps the whole picture and rescales it to different dimensions. If a subject is too small in the frame, crop. If the picture is right but the dimensions are wrong, resize. To hit an exact pixel size without distortion you usually want both, in that order: crop to the right shape first, then resize to the exact numbers.

Not directly. The cropper works in aspect ratios and a drawn rectangle, not typed pixel dimensions, so there is no width and height field here. The reliable route is to crop to the ratio you need, then send the result to the image resizer and type the exact pixels. The ratio you picked means the resize is a clean scale with nothing stretched or trimmed a second time.

You get a PNG, and that is deliberate rather than a limitation we forgot to mention. Decoding a GIF in the browser yields frame one only, so anything written back out would be a single still. Naming that still .gif would imply an animation that no longer exists, so the file is written as PNG instead and the changed extension makes the flattening visible. An animated GIF cannot survive this tool.

Yes. The crop is drawn onto a fresh canvas and encoded from scratch, so no metadata block from the original survives. EXIF, GPS coordinates, camera make and model, timestamps and the embedded thumbnail are all gone from the file you download. Orientation is applied to the pixels before the crop, so nothing arrives rotated. If you crop a photo specifically to remove someone from the frame, the location it was taken goes with it.

No. The cropper takes one image at a time, up to 10 MB, because a crop rectangle is a decision about one specific picture and there is no sensible way to apply the same rectangle to a batch of different photos. The compressor, resizer and converter all take up to 10 images per run, since their settings genuinely do apply uniformly.
