Pixels or percent
Type a new width and height in pixels when a form asks for exact dimensions, such as a photo that must be a set number of pixels wide. Or choose a percentage, such as 50 percent, to make the image half as wide and half as tall.
The aspect ratio is locked by default. When you change the width, the height follows, so faces and documents do not look stretched. Unlock it only if you really need a different shape, and consider cropping instead, which avoids distortion.
Choosing JPG, PNG or WebP
JPG is the safe choice for photos and is accepted almost everywhere. PNG keeps sharp edges and transparency but makes larger files for photos. WebP is often smaller than JPG at similar quality, but some older upload forms do not accept it. If the form lists allowed formats, follow that list.
Setting a maximum size in KB
Many forms set both a pixel size and a file size limit. Fill in the optional maximum file size and the tool keeps the result at or below it. If the image cannot fit at the dimensions you chose, try a smaller size or use the compress image tool.
Resizing happens in your browser, so your photo is not uploaded. Look at the result at full size before you submit it.
