GIMP is actually a free and reasonably good alternative to Photoshop. The app’s UI is not the best or the most modern, however, it has all the tools that you’d find in Photoshop as well. In this article, we are going to talk about How to Fix GIMP Eraser not Working – Tutorial. Let’s begin!

GIMP also has the same tools as Photoshop, however, many of its tools work differently and the workflow is really different. In spite of having the same tools, there is a noticeable difference between the two apps as well.

How to Fix GIMP Eraser not Working – Tutorial

If GIMP Is not fully erasing, then it’s advised that you check your eraser settings and also make sure that the opacity of the eraser is actually set to 100.

GIMP also has an eraser tool that, just like all eraser tools in an image editor, can also delete the part of an image that it is used on. It can also be used to remove a selected part of an image, in order to erase a portion of a masked layer. Or just to simply delete any random line or item.

The eraser tool in GIMP is really simple, however, if you guys are having trouble getting it to work and erase a part of an image, then just try the following fixes.

Select a layer

GIMP’s tools don’t automatically choose the layer that they are used on. If no layer is selected, then a tool generally won’t work. Some effects or tools may also work e.g., a canvas resizes, however, most tools can’t work unless you tell them which layer to work on as well.

  • First of all, open an image in GIMP.
  • On the menu bar, head to Windows>Recently closed docks>layers.
  • In the layers window, just choose a layer. A selected layer has a blue highlight as well.
  • You can use the eraser tool in order to remove a part of the image.

It is also possible that you’ve selected a small part of the image has been selected. That is the selection is active and you guys are not aware of it. The eraser tool won’t work anywhere other than inside the selected portion as well.

  • Press the Shift+Ctrl+A keyboard shortcut in order to unselect everything.
  • Choose a layer.
  • Then use the eraser tool.

Unlock the layer

A locked layer avoids any and all changes from being made to it.

  • First of all, go to the Layers window.
  • Choose the layer you want to erase.
  • At the top, just make sure the icons next to Lock: should all be unselected.
  • If the icons are selected, then tap on them to unselect the icon.
  • You can also use the eraser tool.

Add alpha channel

If you guys are using the eraser tool and you see a solid color appear under the part that you’ve erased rather than a transparent background, your image/file doesn’t have transparency. You need to add the alpha channel in order to add transparency in GIMP.

  • Just open the image in GIMP.
  • Right-tap a layer in the Layers window.
  • From the context menu, you have to select Add Alpha channel.
  • Now use the eraser tool.

Well, the eraser tool isn’t always a solid round-tipped brush. You guys can use all sorts of brushes, and varying degrees of hardness for it actually. The eraser tool’s settings may be avoiding it from erasing the image.

  • Choose the eraser tool from the toolbox.
  • Now make sure the Opacity is 100%.
  • Just set the hardness to 100%.
  • Try to erase now.
  • If it still doesn’t work, then use the reset button in order to reset the erase tool’s settings.

Restart GIMP

  • Just close GIMP completely.
  • Now, you have to wait for a couple of moments.
  • Then start GIMP again.

A lot of users reported that certain glitches prevented them from using the eraser in GIMP. However, after restarting the software, the problem was resolved for good as well.
