Crop Image Online
Cut a JPEG, PNG or WebP down to the part you want, at the picture’s real resolution, without uploading it anywhere.
1 · Choose an image
2 · Choose the crop
The image appears here once you choose one.
3 · Preview and download
No image chosen yet.
The preview is drawn from the picture already in this tab; the download is cut at full source resolution, whatever size the image is displayed at.
Cropping happens in this browser. Your image is not uploaded, stored or logged.
Your file is never sent to a server. It is read and processed by your own browser, and the results are not stored.
How to use it
- Choose a JPEG, PNG or WebP, or drag one onto the drop area.
- Drag the handles to choose the part to keep, or pick a shape such as 1:1 or 16:9.
- Check the pixel size under the preview — that is the region of the original file.
- Choose a format and download the crop at full resolution.
Limits worth knowing
- The crop is cut from the original pixels, not from the picture on screen. A 4,000-pixel photo shown at 800 pixels still exports a 4,000-pixel-wide region at full sharpness.
- Shapes are fitted inside the picture rather than applied by stretching it. Choosing 16:9 on a portrait photo gives you a wide band across it, not a squashed version of the whole thing.
- JPEG has no transparency channel. Cropping a transparent PNG to JPEG flattens it onto the background colour you choose, white by default. PNG and WebP keep transparency.
- Up to 25 MB and 20 megapixels, with no side longer than 8,192 pixels. These are memory limits for the tab doing the work, not a judgement about the file.
- Colour profiles and EXIF metadata are not carried into the cropped file. The pixels and the orientation you saw are kept; camera metadata is not.
- Cropping cannot invent detail. A small region enlarged on screen is still small in the file — this tool exports what is there.
What “exact pixels” means here
A browser shows an image at whatever size the page allows, which is almost never its real size. A 3,000-pixel-wide photo might be displayed at 700 pixels. When you draw a crop over that 700-pixel view, the selection is expressed in screen pixels, and the file has to be cut using the ratio between the two.
This tool does that conversion with the image’s measured and natural sizes, and the number under the preview is the result: the width and height of the region it will actually cut from the file. On a high-density screen the conversion is still correct, because the measurement is of the laid-out element rather than its device pixels.
The practical effect is that a thin slice you select on a shrunk preview can still be a large, sharp piece of the original. Nothing is upscaled and nothing is thrown away beyond the edges you chose.
Choosing a shape without distorting the picture
A ratio preset selects the largest area of that shape that fits inside the picture, centred. On a landscape photo, 9:16 gives you a tall slice from the middle; on a portrait photo it gives you almost the whole frame. In neither case is the image stretched to match the shape, because a stretched portrait is not a crop — it is a distorted copy.
Free crop is the default and has no shape constraint at all. It is the right choice when the goal is removing a background edge or an unwanted object rather than fitting a fixed frame.
The ratio stays locked while you drag, so the selection cannot drift into a slightly different shape at the last moment. Choosing Free unlocks it again without moving what you have already selected.
Formats, transparency and what survives
PNG keeps transparency and is lossless, which makes it the right choice for logos, screenshots and anything with hard edges. WebP also keeps transparency and is usually much smaller. JPEG cannot store transparency at all, so it is flattened onto the colour you choose.
The cropped file is re-encoded rather than copied, because a crop is new pixels rather than a byte range of the old file. That means the output has no EXIF data — including the orientation flag — and no embedded colour profile. For a screenshot or a product photo that is usually welcome; for a photograph whose metadata matters to you, keep the original.
All of this happens in the tab. There is no upload endpoint on this site, no server component that could accept an image, and no analytics that sees a file name.
