How it works
Add your images
Drag and drop, paste, or pick files. They upload over an encrypted connection.
Pick a quality or a target size
Use the quality slider, or tell it exactly how many KB or MB you need.
Download
Save each file, or grab them all at once as a ZIP.
Cropping a PNG is as clean as an edit can be. The format is lossless and the page opens at a setting that keeps it so, which means the pixels inside your rectangle come out exactly as they went in: same colours, same sharpness, same transparency. Nothing is recompressed with loss. Only the pixels outside the rectangle are removed.
Drag the corners of the rectangle to the area you want, or lock it to a ratio such as 1:1 or 16:9. The rectangle moves with the mouse or a finger, and with the arrow keys for small adjustments, which helps when a screenshot has to be trimmed right up to the border of a window or a table.
Transparent areas stay transparent. A batch gives each image its own rectangle, and the results download one by one or as a ZIP. Your PNG files are encrypted on the way to our own servers and are deleted within the hour.
Trimming screenshots
Most PNG files that need cropping are screenshots. A full-screen capture shows a browser frame, a taskbar, a desktop and, somewhere in the middle, the dialog you wanted to show. Crop tightly to that. The reader sees at once what the picture is about, anything private in the surroundings is gone, and the file is a fraction of what it was.
Before sharing a screenshot, look at the part you are keeping as carefully as at the part you are cutting. Open tabs, an email address in a corner, a name in a title bar and notification pop-ups are the usual leaks. A crop removes them for good. A coloured box drawn over them in a document often does not, because the original picture is still underneath.
Empty margins around logos
Logos are often exported on a canvas much larger than the mark, with wide transparent margins that cannot be seen. The trouble starts when the file is placed: the logo looks too small, will not line up with the things next to it, and leaves odd gaps, because the layout program is aligning the invisible canvas and not the visible mark.
Cropping the canvas close to the mark fixes all of that. Leave a few pixels of margin on each side so soft edges are not cut. There is no automatic trim; set the rectangle by eye and check the result on a coloured background.
Circles and avatars
Circle crop cuts an ellipse out of the selected area and makes everything outside it transparent. PNG is the natural format for the result because it stores those transparent corners, with a smooth edge all round the circle. Lock the ratio to 1:1 first if you want a true circle and not an oval. Many platforms show profile pictures as circles but ask you to upload a square and cut the circle themselves; for those, an ordinary 1:1 crop is the right upload, and a circle crop is for the places that display your file as it is.
Frequently asked questions
Is cropping a PNG lossless?
Yes, at this page's settings. The pixels you keep are stored exactly as they were. Only lowering the quality below 90 would change them.
Does the cropped PNG keep its transparent background?
Yes. Transparency inside the rectangle is kept as it is, including partly transparent pixels.
Can I crop precisely, pixel by pixel?
Use the arrow keys to nudge the rectangle. The output size is shown as you go, so you can stop at exactly the width and height you need.
Can transparent margins be trimmed automatically?
No. Set the rectangle by hand, a few pixels outside the artwork.
Why did my cropped PNG become much smaller?
File size follows the area. Half the width and half the height is a quarter of the pixels, and usually close to a quarter of the bytes.
Can I save the cropped image as JPG or WebP?
Yes. Change the format in the editor. JPG fills transparent areas with a colour of your choice, and WebP keeps them transparent.
