Add Watermark: Permissions & Troubleshooting

Generally Add Watermark needs following permissions to be granted on your device:

  • WRITE_EXTERNAL_STORAGE: Allows an application to read from and write to device or external storage.
  • WAKE_LOCK: Allows to keep device from sleeping during processing of multiple images.

Beginning in Android 6.0, users grant permissions to apps while the app is running, not when they install the app.

When you start the app for the first time, you should see a permission request dialog:

Once allowed it doesn’t appear any more. But when you for some reason don’t allow, the app will generate errors when trying to load a source image or save processed image. In this case just restart the app, it will show the permission request again. Press “Allow” and that’s it!

Sometimes the permission request doesn’t appear, instead you see a “Screen overlay detected” message. This is because of another app with a floating overlay like Facebook Messenger, Twilight, CleanMaster, or Lux, that blocks permission requests from other apps. In this case please try to close all such floating activities then launch Add Watermark again. It is supposed to request permission without the “Screen overlay detected” error popping up.

If it didn’t help, follow this step-by-step guide:

Add Watermark: Watermark 360° Panoramas and Photospheres

Since version V3.0 there is full support of EXIF and XMP metadata in Jpeg images. That means, all metadata saved in the original image like photosphere tags, specific copter data, is also present in processed pictures.

For example, you can watermark a photosphere (360° panorama) to produce awesome 3D text effects. Viewing or posting processed pictures e.g. to Facebook works the same way like with original images. Make your spherical panoramas to eye-catcher!


How Facebook does determine whether a photo is in 360:
– The photo must have a 2:1 aspect ratio, with maximum file dimensions of 6000 x 3000 pixels
– The Exif XMP tag “ProjectionType=equirectangular”

Add Watermark: How To Reuse Recent Watermarks (Profiles)

Since the new version 3.0 you can easy recall up to 20 recently used watermarks with all their properties. Like using profiles to quick switch between many predefined settings. How this works:

Each time you save resulting image the app stores all watermark settings in the list “Recent texts” or “Recent images” depending on the current watermark type.

To reuse one of last used watermarks please follow the steps:

  • Open Settings (pressing edit or gear button)
  • Go to Text or Image settings depending on your need
  • Press button “Recent texts” or “Recent images”
  • Choose an entry from the list
  • You can see immediately the loaded settings
  • Close Settings (pressing the back button) to see how the watermark looks on the preview
  • Now you can save the resulting image

Please don’t forget: as a confirmation you need to save your resulting image to make sure your new/changed watermark’s properties can be recalled from the recent list.

If you apply changes to a recent watermark, they will be updated while saving resulting image until you change the watermark content itself (text or watermark file name). Then it will be saved under a new name.

After a new installation the list “Recent texts” already contains a preloaded set of watermark samples. Try them out!

The earlier watermarks (>20) will be replaced with last ones. Last saved comes always up in the list.

List of “Recent images” saves both types of image watermarks: built-in stickers and user’s custom logos.

Add Watermark: How To Use Built-in Stickers

Since version 3.0 there is a set of built-in watermark images (stickers) you can use for your images. Also in the free version!

To add a such sticker just:

  • Open Settings (pressing gear button )
  • Go to Image settings
  • Make sure the watermark type is set to “Image”
  • Press button “Biult-in stickers”
  • Choose one image from the list
  • Close Settings (pressing the back button)
  • On the preview adjust opacity, position and rotation
  • Now you can save the resulting image

Add Watermark: How To Process Multiple Images From Dropbox

When you are storing your images in Dropbox cloud, you may be wondering, how to watermark more than one image using batch mode. Because currently in Dropbox you can select only one single file to send it to another app.

Please find below a workaround. To say it short, you need first to download images to device.

1. Start Dropbox and mark needed images, then save them to device (use three point menu > save to device):

Inline image 1
2. When they are saved (you can see the status on icons), open Add Watermark, select source (+) > process multiple images
3. Navigate to the Dropbox folder – it looks similar to
select all images, then process them.
I don’t recommend to process more than 100 images at once, as it can take very long time (few minutes).
