Image resizing
Reduce or enlarge images in pixels, percent or by the long side. Proportions are kept. Everything happens in the browser, files are not uploaded anywhere.
Resizing an image means recalculating its width and height in pixels. Reducing it produces a light file for a website, an email or a social network, while enlarging prepares the picture for a screen or a larger print format. The page works right in the browser.
There are 3 ways to set the new size. You can specify the long side, including by choosing a typical value such as 1500 or 1920 pixels. You can enter the width and height manually, or change the scale in percent relative to the original.
The keep-proportions option prevents distortion: when one side is changed, the other is recalculated automatically. If the proportions need to be changed, this option is turned off and the dimensions are set independently, knowing that the image will be stretched or squeezed.
A photo can be resized with enlargement turned off. Then pictures that are already smaller than the set value remain unchanged. For pixel art and icons there is a mode without smoothing, which keeps sharp boundaries between pixels.
When reducing, high-quality interpolation is applied, so fine details are preserved better. Enlarging adds no new information but only stretches the existing pixels, so strong enlargement leads to blurring. After the page is closed, temporary data is removed from browser memory.
Finished images can be saved in the original format, as well as in JPG, PNG or WebP with a choice of quality. All operations are performed on your device, and files are not uploaded to a server. For large files it is advisable to have enough RAM.
