Paste a screenshot, make it look good. Runs on your device.
A raw screenshot ends at the edge of the window, so it looks cramped next to a post or a slide. Three things fix that. Space around the picture gives the eye somewhere to rest: the default padding is 8% of the screenshot's width, and the slider goes to 20%. Rounded corners soften the hard rectangle; 16 px is the default and 48 px is the most the slider allows. A soft shadow lifts the screenshot off the background, and the Strong setting is for pale backgrounds where a soft one nearly disappears. The window frame adds a title bar with three coloured dots, in a light or a dark version. It has no address bar text, no logos and no brand names, so it suits any screenshot, not only one taken in a browser. Padding 0 with a corner radius of 48 gives a tight, very round card where only the corners show the background.
Auto makes the canvas just big enough for the screenshot and its padding. The other choices grow the canvas to a fixed shape and centre the screenshot in it. 16:9 suits slides and video thumbnails. 1:1 is a square for feeds and avatars. 4:5 is a portrait shape. 1.91:1 is the wide shape commonly used for link preview images. The canvas only ever grows, never crops: a tall screenshot on a 16:9 canvas gets a wide canvas with extra background on both sides, not a squeezed picture. For example, a 1600 by 900 screenshot at 8% padding is 928 by 578 in layout units, and the 1:1 choice turns that into 928 by 928 with the screenshot centred. If you need an exact pixel size for a post, make the PNG here and then use the Resize Image tool.
The PNG is made at twice the layout size, so a screenshot up to 2400 pixels wide is drawn pixel for pixel and stays sharp on high-density screens. A wider screenshot is scaled down to 2400 pixels; no screenshot is ever enlarged, so a small one gives a small image. The size shown above the Create PNG button is the size of the file you will get. Some devices, mostly phones, limit how large a canvas can be. When that happens the export drops to 1.5 times or 1 times the layout size, and the page says so before you create the file. PNG keeps flat colours and text clean, but the files can be large with a big canvas. If you need a smaller file, send the result through Compress Image.
The screenshot is read and drawn by your browser, on a canvas inside this tab. It is not uploaded, and there is no server that receives pictures. Copy image puts the PNG on your own clipboard. The page counts visits with Google Analytics using rough groups, for example that a tool was opened or that Copy was clicked, and never a file name, an image or an exact size. Your style choices, such as the background and padding, are saved in this browser so they are there next time. The screenshot itself is never saved: close the tab and it is gone.
Press Ctrl+V (Command+V on a Mac) while this page is open and no text box has focus. The clipboard must hold an image: on Windows, Win+Shift+S copies a region; on a Mac, Control with Shift, Command and 4 copies a region. If the Paste from clipboard button is shown and the browser blocks it, use the keyboard shortcut, or choose a PNG, JPEG or WebP file instead.
The PNG has twice as many pixels across as the layout you see. A screenshot 1600 pixels wide is shown 800 layout units wide and exported at 1600 pixels, drawn pixel for pixel. Images wider than 2400 pixels are scaled down to 2400. If the device cannot make a canvas that large, the export is made at 1.5 times or 1 times and a notice says so.
Choose 1.91:1. It is a wide shape, about 1200 by 628 pixels when the canvas is that size, and it is commonly used for link preview images. The canvas only grows to reach the shape, so your screenshot is never cropped. For an exact pixel size, create the PNG here and use Resize Image.
The transparent parts show the background you picked, so the saved PNG has no see-through areas. The shadow follows the rectangle of the whole screenshot, not the shape of what is drawn in it, so a screenshot with rounded transparent corners of its own still gets a rectangular shadow.
Not yet. This tool changes what is around the screenshot: background, padding, corners, shadow and frame. Arrows, text boxes and blurred areas are not part of it. To hide part of an image, blur or cover it in an editor first, then paste the edited picture here.
Copying a picture needs a browser that can put images on the clipboard, and some cannot. Where the button is missing, use Create PNG and download the file. If the button is there but the copy is refused, a message says so and the download still works.
