裁剪完成
-
This page crops to JPEG. The selection is constrained to that shape, so you can concentrate on framing the subject instead of dragging corners until the numbers line up.
How it works
- Drop in your image — it is read locally, not uploaded.
- The crop box is already constrained to JPEG.
- Drag the box over the part of the picture you want to keep.
- Download the cropped result at full resolution.
Good to know
Cropping removes pixels rather than scaling them, so what you keep stays exactly as sharp as it was in the original file.
Frequently asked questions
Does cropping to JPEG reduce image quality?
No. Cropping discards the area outside your selection and leaves the remaining pixels untouched, so the kept region is bit-for-bit as sharp as the original.
Can I crop to JPEG without losing the subject?
Position the crop box before downloading — the preview shows exactly what will remain. If the subject does not fit the shape, consider resizing with padding instead so nothing is lost.
