Things you can do with uMark other than watermarking
uMark is the best batch photo watermark software out there. However, there are other things that you can do with uMark other than watermarking your photos. Let us see.

1. Batch resize photos with uMark

You can use uMark to resize multiple photos at once. To do this, select your photos by clicking on Add Images button, then without adding any watermarks, click on Save Images button. Then on the Output options window, select the Resize option.

You can resize the photo in several ways. You can set the new with and height values in percentage format so images will be resized proportionately to their original pixel size. For instance, a 6000 X 4000 pixel image can be resized to 1500 X 1000 pixels by setting Width and Height at 25%.

You can also set the width and height to absolute pixel values or you can set the size of the longest side of the image.

If you set the longest side to 2000, then portrait (vertical) images will be resized down to images with a height of 2000 pixels with width being calculated automatically based on the original image size and landscape (horizontal) images will be set to 2000 pixels width with height being calculated automatically.

After selecting the values just click on the Start button and uMark will save the resized images in the output folder selected.

2. Batch convert photos with uMark

You can convert the photos from one type to another with uMark. For example, you can convert all your JPG images to PNG or PNG images to GIF or JPG or convert TIFF to PNG in a batch. If your images are in BMP format, you can convert them to JPG or GIF.

Select the images by clicking on the Add Images button or select an entire folder by clicking on Add Folder button. After selecting images, click on the Save Images button without adding any watermark.

On the Output options window, select the new image format from the Output format dropdown menu.

Finally, click on the Start button and the images will be saved in the selected output folder in the new format.

3. Convert photos to PDF with uMark

If you want to create a PDF file out of photos, you can do that with uMark.

Select all the photos you want to convert to PDF by clicking on the Add Images or Add Folder buttons.

Click on Save Images and on Output options window, select pdf from Output format dropdown menu.

You have the option of converting each photo individually or merging all photos into a single PDF file. Select the merge option if you wish and click on the Start button.

The photos will be saved in the selected output folder as a PDF file - one or multiple based on what you had chosen.

4. Remove EXIF data from photos with uMark

When you take photos, the camera adds a lot of information to your photo which is called EXIF metadata. This information includes the technical parameters of the photo like the aperture, focal length, shutter speed, make and model of the camera, date and time of the photo and also location information where the photo was taken.

You may want to remove some or all of this data for privacy and security reasons. You can remove EXIF data from multiple photos at once with uMark.

Select your photos by clicking on Add Images button then click on Save Images button and on the Output options window you can see the option of keeping or removing metadata.

There are 4 options –

Include All Keeps all the metadata in the photo
Copyright only Keeps only copyright related EXIF data and removes all the other EXIF data
Exclude geo location Removes the geo location data from photos. It is advisable that you should remove geo location data before sharing family photos online
Exclude all Removes all EXIF metadata from the photos

Select the appropriate option and click on Start button. uMark will save the photos in the selected Output folder after removing the EXIF data as per your choice.

5. Batch rename photos with uMark

You can rename a bunch of photos at once with uMark. This is especially useful when you want to name your photos with a series of numbers like Img-001, Img-002, Img-003… or Design-201, Design-202, Design-203… or Product55, Product56, Product57… etc.

First, select your photos you want to rename by clicking on the Add Images button. You can also add all images in a folder by clicking the Add Folder button. Then, click on the Save Images button and on the Output Options window select the Rename option.

Now you need to specify a renaming pattern or a rename macro.

If you set rename format to [O] then the photos will be saved with their original name.

If you want to name the photos in a series then you need to use a number macro. Click on the Insert rename macro button and select the appropriate digit counter option. If you want your images to have a 1,2,3 or 4 digit number select it.

You will now see a prompt which will ask you the starting number of the series. By default it is 1 which means the naming of images will start from 1. If you want it to start from any other number then provide that number and click on OK.

You can add any additional words to be used in the name before or after the macro text. Like Photo-, Design, Travel, project name, client name or anything you want.

If you set the rename format to Img-[#101], the images will be named as Img-101, Img-102, Img-103… and so on.

Click on the Start button and the photos will be saved in the selected output folder with new names as per your preference.


You can also use all the above options together. So, you can batch convert and resize the photos at the same time and also rename them while you are at it. You can make all photos of the same width while creating a PDF file out of them or remove the geo location from photos while renaming them in bulk. The possibilities are limitless.
