Editorial review


Margie Smeer Senior editor

The following review written by one of the Software Informer contributors applies to version 4.3
The most popular and also effective manner of protecting your photos against being counterfeited, stolen or used without your authorization is having them watermarked. Though watermarking is a rather simple process, performing it without the right tools can be quite tedious and difficult.
UMark is one of these right tools, as it makes photo watermarking simple, easy and fast.

UMark allows you to easily watermark multiple photos at the same time, in batches. It supports processing images of various formats, including popular ones like JPG, PNG, GIF or BMP. Furthermore, it offers different watermarking possibilities. For example, it lets you apply text watermarks to your photos, but also watermarks consisting of other images (such as logos), shapes or even QR codes. Various aspects of the watermarks, such as the position or size, can be easily customized by the users, to their liking.

UMark even lets you add some basic effects to the watermarked images: borders and shadows. Even though it’s a feature-rich tool that comes with a lot of functions, UMark is really simple and easy-to-use. There are no intricate settings and its interface is really straightforward and intuitive.

As you can see, UMark offers a lot of advantages yet it comes with a reasonable price. It gets my complete recommendation, as it works flawlessly and leaves no room for complaint.


  • Can batch process multiple images at once.
  • It's easy-to-use and straightforward.
  • Lets you add borders and shadows to the photos.


  • The interface cannot be customized.
  • Though it's simple-to-use, it could use a step-by-step wizard.

What's new in version 5.3

uMark 5.3 for Windows
A new version of uMark for Windows is here with new features and bug fixes.

uMark now works well with low resolution devices
More and more users are using uMark on low resolution devices like netbooks and tablets and the fixed size of uMark's text watermark options window was causing a problem as users were not able to see the bottom of the window and hence were not able to set some of the options. That has now been fixed. Users on low resolution devices will now be able to scroll to the bottom of the text watermark options window.

Adjustable increments in auto numbers
We have added an ability to specify the increment value for auto numbers. Previously you could only number the images by the increment of 1 but now you can specify the increment count. So if you want your images to be numbered 10,20,30... then you can specify the increment value to be 10. Or if you want the numbers to be 5,10,15,20... then you can specify the increment value to be 5. Auto numbers are a great way to number your photos.

Quick tip - uMark can remember the last auto number it gave so the next time you watermark more photos you can continue from the same number.

Selective processing
We have added the ability to process selective images from all the images you have added in uMark. Earlier you had to watermark all photos at once, if you wanted to watermark certain photos differently then you had to do it in a different batch. Now you can do it all in single batch with selective watermarking. You can check the photos you want to watermark and uMark will only watermark those photos. And once you are done with processing them you can use the toggle check option and uMark will flip the checkmarks on all photos, checked photos will be unchecked and unchecked photos will be checked.

Other than these new features we have also fixed some bugs, so it should make using uMark easier than before.

What's new in version 4.4

It adds option to save watermarked photos as PDF and maintains directory structure. uMark can now save watermarked photos as PDF documents. If you want to send some sample photos to a prospective client, you can send them as PDF instead of sending individual images. You can choose to put all photos you are watermarking in a single PDF file or you can have uMark save them as individual PDF documents.

What's new in version 3.7

Add EXIF properties as watermark, add multiple watermarks, add image name, folder name, creation or modification date as watermark, drag and drop images to uMark from Windows Explorer

What's new in version 3.4

- Unlimited watermarks can be added
- EXIF properties can be added as watermarks
- Supports multiple languages
- Faster processing, better memory utilization
- Built using latest Microsoft .Net Framework 3.5 and Windows Presentation Foundation.
