Type the exact pixels you need, or use one of the common-size pages below.
"Fit" keeps the whole image with no cropping; "Fill" crops to match the exact dimensions.
"Fit" scales the image to fit inside your target dimensions without cropping anything, so the result may not exactly match your width and height. "Fill" crops the image so the output is exactly the size you set — the standard choice for profile pictures and banners.
Shrinking an image barely affects quality. Enlarging a small image beyond its original size will look softer, since no tool can invent detail that was not captured.
No. Resizing happens entirely in your browser using canvas — the image never leaves your device.

Every image has a width and a height in pixels, and the relationship between them is its aspect ratio. Problems appear when the ratio you are resizing to does not match the ratio you started with. A photograph that is wider than it is tall cannot become a perfect square without something being given up, so the tool has to either shrink the whole picture until it fits inside the square and pad the gaps, or fill the square completely and cut off the overflow. That choice is the fit and fill setting, and it is the single most useful thing to understand on this page.
Fit keeps the entire image visible. Nothing is cut away, and any space left over is filled in, which is the right choice when losing part of the picture would matter, such as a product photo where the edges count or a diagram where cropping would remove a label. Fill covers the whole target area edge to edge and trims whatever does not fit. That is what you want for wallpapers, thumbnails, banners and avatars, where a clean rectangle with no borders looks far better than a letterboxed one.
Making an image smaller is reliable, because the detail is already there and the tool is discarding some of it. Making one larger is not, because the extra pixels have to be invented by averaging between the ones that exist. A small image stretched to a large size looks soft and slightly smeared no matter which tool does it. If you need a large final image, start from the largest original you have rather than from a copy that has already been shrunk once.
Most of the dimensions people search for are tied to a specific slot. A thousand and eighty by a thousand and eighty is the square social post. Twelve hundred by six hundred and thirty is the preview card most platforms generate when a link is shared. Five hundred and twelve by five hundred and twelve and four hundred by four hundred are icon and avatar sizes. Nineteen twenty by ten eighty is a Full HD screen. If a site gives you a number, use exactly that number, because platforms that resize for you often do it worse than you would.
If a form wants both specific dimensions and a file size limit, set the dimensions here first and then use the image compressor to meet the kilobyte target. Reducing the dimensions usually does most of the work on its own, since a picture with fewer pixels has less to store, and the compressor then only has to make a small adjustment rather than a drastic one.
