A product cutout

pro tips
Pick the destination ratio before dragging. Adjusting afterwards means starting the selection again.
Leave a little margin around a face or a logo; tight crops feel cramped at small sizes.
Use PNG for graphics with sharp edges and JPEG for photographs.
what it does
Open an image, drag a rectangle over the part you want, and apply the crop. The preview keeps the original aspect ratio, so what you see is the image, not a stretched version of it.
The aspect presets are the reason this is quicker than a full editor. Pick 1:1 for an avatar, 16:9 for a video thumbnail, 4:3 for a slide, or leave it free and draw whatever shape you need.
The crop is taken from the original pixels, not from the scaled preview. A 4000 by 3000 photo cropped to half its width and height becomes a 2000 by 1500 JPEG or PNG, with no upscaling and no blur.
Apply the crop, check the result, then download. Everything happens on a canvas in your browser; the file is never uploaded.
quick answers
Does cropping reduce the image quality?
The crop keeps the original pixels inside the selection. JPEG output re-encodes once, so use a high quality if you plan to edit further.
Can I crop to an exact size in pixels?
This version crops by dragging and by aspect ratio. For exact dimensions, crop here and then use the image resizer.
Is the preview stretched?
No. The preview preserves the original aspect ratio, and the crop is calculated from the image's real pixels.
