How to resize your images:

  1. Click on "Select Images" or drag and drop your photos into the app using your cursor. You can upload photos from your computer, Google Drive, Google Photos or DropBox.
  2. Once all the photos are uploaded, click on "Resize Images". This will take you to the Output settings, where you have to choose how you want your images to be resized: "Fit Width", "Fit Height" or "Fit into Rectangle". If you select either of these options, you will need to enter the necessary value of height/width or both in pixels into the bars below. Also, you can simply reduce the size of your entire photo by selecting the "Percentage" option.
  3. Next, you have to choose the file format. There are 3 options: “Original format”, “Convert to JPEG” or “Convert to JPEG and compress”. With the latter one, your resized copies will take up less memory space, yet their quality won’t be compromised.
  4. Once you are done with specifying the settings, click on "Resize Image" to start the process. Resized copies can be uploaded to your computer, Google Drive or Dropbox.

Safety and reliability

Watermarkly is a web-based application. You don't need to install anything on your computer. The app works in your browser and doesn’t require any additional software or plugins. By installing software from unknown sources, you might involuntarily infect your computer with a virus.

We don't keep your images on our servers or have access to them. Nobody in our company can get access to your files, no matter what.

The app is completely free. Moreover, it is not swamped with ads or pop-ups. Nothing will distract you from resizing your images.

Our online Resizer allows you to process up to 10 images per day at no additional cost. But, if you need a tool to resize large batches of files, you should consider buying the paid version of the app. With it, you will be able to resize up to 2000 images in one go.

Resizing options

In the app’s settings, you can choose one of the 4 resizing options: "Fit Width", "Fit Height", "Fit into Rectangle" or "Percentage".

With the first two options, you have to enter the max value of width or height in pixels. Then the size of the other side will be adjusted automatically.

If you select the "Fit into Rectangle" option, you will need to type in the necessary values of both height and width in pixels.

The "Percentage" option can come in handy if you want to reduce the size of your images not to the exact pixel dimensions, but approximately. For instance, if you enter 60%, the app 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 app, 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.

When you should resize your images

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

For example, when posting images on your website, you should keep in mind that files of smaller size and resolution are going to be loaded and downloaded faster; this is the experience that most of your website visitors expect to get.

Web pages with correctly resized images are better indexed in the search engines because the smaller size of images accelerates your website’s loading speed. Plus, by using our online tool, you will ensure that your resized images will look just as great as the originals.

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, 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 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.
