Watermarkly Image Resizing Options

In the app’s settings, you can choose one of the 5 resizing options: "Exact width", "Exact Height", "Exact width & height", "Maximum width & height" or "Percentage".

With the first two options, you have to enter the exact number of width or height in pixels. You will have control over only one value since our photo resizer will change the size of the other side automatically.

For example. You upload a vertical photo that’s 5835 x 3890px and choose the “Exact height” option in the Output Settings. Next, you type in “2000” into the bar below. After the resizing process is done, you will get the image that has the height of 2000 pixels and the width of 1333 pixels. The width was altered automatically to preserve the aspect ratio of your original image.

The "Exact width & height" and “Maximum width & height” may seem similar, but they work differently.

Let’s say, you upload the same vertical image from the previous example – its size is 5835 x 3890px – and choose "Exact width & height", then enter 2500 for width and 2500 for height. These settings will produce a rectangular image. But your photo won’t be awkwardly cropped. Instead, it will be placed against a blurry background.

However, if you upload the same photo, choose "Maximum width & height", and enter 2500 for width and 2500 for height, you won’t get a rectangular image as the result. The height of your image will be changed to 2500 pixels, while its width will be reduced to a smaller number. The size of the original photo is 5835 x 3890px. So, its resized copy will become 2500 x 1667 pixels.

The "Percentage" option can come in handy if you want to reduce the size of your image not to the exact pixel dimensions, but approximately. For instance, if you enter 60%, the photo resizer will reduce the width and height of the original image by 40%.

Your output settings will be saved.

Therefore, the next time you open the image resizer, you will see the same values and options that you entered and selected during the last resizing.

This can make the whole process quicker and easier if you always resize your images the same way.

What Image Resolution Is

Digital images produced by cameras and smartphones consist of pixels. In the world of photography, resolution is the number of pixels an image contains. Naturally, the higher the resolution the better the quality of a photo. But at the same time, if your image contains a lot of pixels, its file size will also be quite large; in case you don’t know what a file size is, it’s the amount of bytes your file takes up in your device’s memory.

Figuring out image resolution is actually quite simple. It’s represented by pixel dimensions. For example, if your image is 6000 pixels wide and 4000 pixels high, then its resolution is 6000 x 4000 pixels.

High-resolution images that have a large file size are often impossible or incredibly difficult to upload to social networks and websites or send by email. If either of these is an issue you’re currently facing and eager to solve, you’ll simply need to resize photo. By resizing, we mean changing their pixel dimensions and subsequently, decreasing their file size.

Where You Can Check the Image Resolution?

The resolution of a photo can be checked in your digital camera or professional image editing software like Photoshop. There is another, simpler way to do it, though. Open a folder where your photo is. Right click on the file and select “Properties” if you are on Windows or “Get Info” if you are on Mac. Next, go to the “Detail” tab – there you will find all the information about your image, including its resolution.

To find out the resolution of a photo on your phone, open it in your gallery and look for the “Information” icon – an “i” in a circle. Tap on it to see the image properties. Pixel dimensions will be displayed like this – 2200x1500.

Knowing image resolution is important because it will allow you to resize photo properly and without messing up its aspect ratio. But if you are still having trouble figuring out what pixel dimensions of your image are, don’t worry. For your convenience, our image resizer offers a little preview. On the left, you’ll see the height and width of your original image, while on the right, you’ll find the pixel dimension that your resized copies will have. Thanks to this feature, you’ll be able to adjust the settings to achieve the desired results before the resizing process starts.

When You Should Resize Your Photos

Our image resizer can be of use if you need to prepare your high-resolution photos for publishing online.

If you upload your high-resolution, large-sized files to your website, you may not only experience difficulties in its operation but also the sharpness of your images will be affected since the browser will be forced to compress them; and it won’t do a proper job at it.

In addition, changing the width and height of your images will allow you to correctly prepare them for publication on social networks, where posts, ads, headers, profile pics, and so on have their own required dimensions. By resizing images, you will avoid awkward cropping or terrible compressing of the originals, and your photos will look exactly as intended.

Our fast and easy-to-use photo resizer can also help in case you need to send your photos as attachments. As you may know, all email services have file size limits. Reducing the size of your images will allow you to attach more of them to your letter.
