Remove watermark from image with Gimp

1. The quick and simple method

You can very easily heal an image stamped with watermark in GIMP. Bear in mind though that in case of the semi-transparent watermarks it is not a precise restoration of the image mathematically to its former self, indeed  it is sooner “healing” of the image, as parts of it are filled with newly generated content to make it blend with the rest of the picture. Still this method is good enough for most of the everyday situations and more often than not produces really good results.

You need the Resynthesizer Gimp plug-in to do this (available also for Windows).

Install the plug-in by:

 sudo apt-get install gimp-resynthesizer


  • open the picture with GIMP
  • select the area you want to heal (the more precise the better)
  • select Filters > Map > Resynthesizer
  • click Ok
2. The more complicated method
This way is manual labor intensive and may not always work.
In case of a semi-transparent uniformly white watermark on either color or grayscale image:
  • Create exact replica of the watermark as semi-transparent white on solid back
  • Invert colors
  • Place this image as a layer above the image you want to remove the watermark from
  • In the “Layers” window set the mode of the top layer to “Burn”
You can read more about it here . Still, I have not got it to work in the real life, although it works perfectly as described with the sample images provided.

    I have spent a couple of hours trying to find the resynthesizer plugin in a Windows-friendly form. That’s the overall problem with Gimp – you need a masters in computer science to use it, or to even understand what other users are talking about.

    Just download Gimp 2.8.10 from Partha, which comes with everything you could ever need, including resynthisizer, G’MIC filters, Python scripts & more! The best build I’ve ever seen. Works flawlessly on 10.7 & 10.8.
