An image resizer is a tool or program that allows you to change the size of an image. Typically, it works by changing the number of pixels in an image, either by adding or removing pixels to make the image larger or smaller.
Image resizers are commonly used to make images smaller so that they take up less disk space, load faster on web pages, and are easier to share or send via email or messaging apps. They can also be used to make images larger, although this can result in a loss of image quality, especially if the original image is small or has a low resolution.
Some image resizers are standalone programs that you install on your computer, while others are web-based tools that you can access through a browser. Some image editing software, such as Adobe Photoshop or GIMP, also include built-in image resizing tools.
Most image resizers allow you to set the desired size of the image, either in pixels or as a percentage of the original size. Some also include options for maintaining the aspect ratio of the image, which can prevent the image from becoming distorted or stretched when it is resized. Additionally, some resizers may offer other features, such as the ability to change the file format, or adjust the image quality or compression settings.
Overall, an image resizer is a useful tool for anyone who needs to change the size of an image for any reason, whether it's to save disk space, share images online, print them or create images for use in a website, app, project or presentation.
Our free image resizer provides all those features directly on your browser, without the need to download or pay for any tool.
When a photo is taken with a camera, the camera's sensor captures the light and color information and converts it into digital data. This data is then compressed and saved as a file, typically in the JPEG format. The file size of the photo is determined by the amount of data that is captured and saved in the image.
Images are composed by several dots called pixels, and each of them has a color, represented as a combination of three basic colors (red, green and blue). To store each of these pixels, 3 bytes (24 ones or zeros) are generally used. When an image is large, it may have millions of pixels, and that means storing all information fo...
