Image Cropper

Choose a picture, drag a selection or type its left edge, top edge, width and height in source pixels, then download the crop. Use a 1:1 square, a 16:9 or 4:3 rectangle, a circle, or rounded corners with a radius you choose. The output uses the selection’s original pixel dimensions even when the preview is smaller. PNG preserves transparent corners; JPEG fills them with a background colour. Your picture stays in this browser, the original file stays untouched, and no account is needed.

Every pixel inside the box, and nothing else. Drag a box over the picture, or drag its corners. Arrow keys move the selection and shift with an arrow resizes it, a step at a time. The numbers below are the picture's own pixels, which is what the file is cut from, so a preview shown smaller than the picture still downloads the selection at full size.

The crop is exact and the original is never altered. The box you drag is mapped back to the picture's own pixels, so the file you download is the selection at full resolution and not a scaled copy of the preview. The original is never changed. A circle or rounded crop keeps real transparency in PNG; JPEG has none, so it is filled with the background colour you pick. The picture is opened and written inside this tab, and the only thing kept between visits is the shape, ratio and format you last used.

Common questions

What does cropping an image do?
Cropping keeps the selected area and leaves out the surrounding edges in the downloaded copy. It does not shrink the entire picture, remove an interior hole or cut a person away from their background. You choose which part remains by moving the selection.
Does the crop come out at the full resolution of the original?
Yes, and that is the one thing this tool is built around. The selection is never stored in preview coordinates: every drag is divided by the preview scale and rounded to whole source pixels the moment it happens, so a 4000 pixel wide photograph shown 1200 pixels wide on screen is being previewed at a scale of 0.3, and a 300 pixel box you drag over it is a 1000 pixel selection of the picture itself. The Output row names the size the file will be before you save it, and it is the same pair of numbers as the width and height in the Selection row. Nothing is scaled on the way out: the canvas the crop is drawn onto is exactly the size of the selection.
How does the circle crop handle transparency?
It cuts the picture with a real clipping path, so the corners outside the circle hold no pixels at all rather than white ones painted on top. Saved as PNG, those corners are genuinely transparent and stay transparent when you place the file over another background. Because a circle is drawn inside a square, choosing Circle locks the ratio at 1:1 and the other ratio buttons are switched off: an oval selection would not give you the circle you asked for. Rounded works the same way, with the corners cut to the radius you set.
What happens if I save a circle or rounded crop as JPEG?
JPEG has no transparency at all, so the corners have to become some colour. Choosing JPEG with a circle or rounded shape shows a Background control, set to white to begin with, and that colour is painted underneath the crop before the picture is drawn, so the corners come out in it. If you want the corners to stay clear, choose PNG instead. A plain rectangular crop needs none of this, since it has no transparent part to fill.
Is my picture uploaded anywhere?
No. There is no server in this. The file is read in the page, decoded by the browser's own image decoder, drawn onto a canvas at the selection's size and handed back to you as a download. No image byte is sent to an endpoint, to analytics or to error reporting. The only thing written to your browser's storage is the setting row: the shape, the ratio and the output format you last used. No picture is ever stored, and if storage is blocked the tool still works.
Can I crop to an exact 1:1 or 16:9 ratio?
Yes, and exactly rather than nearly. A locked selection is snapped to a whole multiple of the ratio, so a 16:9 crop comes out as a size like 1600 by 900 that divides evenly, and 4:3 and 1:1 do the same. Dragging a corner grows the locked box to cover the movement in either direction, and it stops at the edge of the picture rather than escaping it: if there is not room for the size you are dragging towards, the box shrinks to the largest one of that ratio that still fits. Free leaves the box any shape you like.
Can I set the crop without using a mouse?
Yes. Enter Left (x), Top (y), Width and Height in pixels and press Apply pixels. The values are measured from the top-left corner of the original image. You can also tab to the selection and move it with the arrow keys, or hold Shift to resize it. The four corner handles are keyboard controls too. The Selection row shows the applied coordinates; Copy copies those four numbers.
Is there a limit on the size of the picture?
None is imposed. Nothing is uploaded, so the bytes on disk are nobody's business, and there is no megapixel cap on what you can open or crop. The practical ceiling is your own machine: a browser that cannot allocate a canvas for a very large crop says so in plain words, with what to try instead, rather than handing you a blank file.
Which formats can it open, and what does it save?
It opens image files your browser can decode, including JPEG, PNG, WebP, GIF and usually AVIF, and saves PNG or JPEG. WebP input is accepted but WebP output is not offered. PNG avoids another lossy compression pass and keeps transparency; JPEG is encoded at high quality and can change fine detail. Animated images become one still frame. An SVG that the browser can display becomes raster pixels, not an editable vector crop. The saved file is named after the original with the crop dimensions added.
Does cropping change my original file?
No. The picture you choose is only ever read. The crop is drawn onto a new canvas and handed to you as a new download, named separately, and your file on disk is untouched. Reset crop puts the selection back to the centred box it opened with, and Use all sets it to the whole picture, so nothing you do here is irreversible.
How do I crop an image to 300 by 300 pixels or another exact size?
Choose Rectangle, select 1:1 for a square or Free for an unrestricted rectangle, and enter the width and height in pixels. Set Left (x) and Top (y) to position it, then press Apply pixels. A 300 by 300 crop must fit inside the original image. A locked ratio must match the typed dimensions; the tool tells you when they do not match instead of silently changing the size. The Output row shows the applied size before you download.
How is cropping different from resizing?
Cropping keeps part of a picture at its existing pixel size. To make that part larger or smaller, save the crop and open it in Image Resizer. Its Fill mode can also resize and crop the centre to a target box in one step. For an Instagram post, its Instagram page offers square and portrait sizes; check the posting preview because different app surfaces can frame the image differently.
Can I crop several images, rotate a crop or reduce its file size?
This cropper edits one image at a time. Image Resizer can apply a centred Fill crop to a queue of images, although it does not offer a separate manually positioned crop for each image. To rotate, use Image Flipper for a 90, 180 or 270 degree turn, then open that file here. To meet a KB or MB upload limit, save your crop and open it in Image Compressor; fewer pixels do not guarantee a particular file size.
Does Free mean freehand, automatic or AI cropping?
Free means an unlocked rectangular aspect ratio. You still position the crop yourself. There is no lasso, subject detection, background removal, automatic edge trimming, oval, star or other custom outline here. Circle and Rounded are the two masks available in addition to Rectangle.
Can I crop a PDF page or extract a picture from a PDF?
Use PDF Cropper to trim the visible page and keep PDF output. A PDF crop hides content outside the box; it does not redact or delete that content. To save an area as a picture, first render the relevant page with PDF to Image, then open the resulting PNG here and crop it. That gives you pixels at the chosen rendering resolution, not necessarily the original embedded image.
Can I make a 2 by 2 inch or 4 by 6 print?
This cropper works in pixels, not inches or centimetres. Use Pixels to Print Size to calculate the needed pixels at your chosen print resolution. At 300 pixels per inch, a 2 by 2 inch print needs 600 by 600 pixels and a 4 by 6 inch print needs 1200 by 1800 pixels. Use Image Resizer if scaling is needed, then Image DPI Changer to set the stored resolution in a JPEG or PNG. Confirm the physical size in your print software. A square crop alone does not check passport or visa photo requirements.

The box you drag is mapped back to the picture's own pixels, so the file you download is the selection at full resolution and not a scaled copy of the preview. The original is never changed. A circle or rounded crop keeps real transparency in PNG; JPEG has none, so it is filled with the background colour you pick.
