Remove Objects From Photos
Brush over something you do not want and WoWPixel fills the gap from the surrounding image. It is particularly effective on visible AI watermarks - including the Gemini watermark - and on small, simple objects.
What this is genuinely good at
Object removal works by inpainting: the marked area is discarded and reconstructed from the pixels around it. That makes it very strong in some situations and weak in others, and it is worth knowing which is which before you spend time on it.
- Visible AI watermarks - the small corner watermark that image generators such as Gemini stamp onto output is close to an ideal case. It is small, sits over predictable background, and clears cleanly.
- Small, simple objects - a stray sign, a blemish, a power line, a date stamp, a piece of litter on an even surface.
- Objects on uniform backgrounds - anything sitting on sky, a wall, sand, grass or a plain studio backdrop, where there is consistent texture to rebuild from.
Where it will struggle
Be realistic about large or complicated removals. Inpainting can only invent detail that is consistent with the surroundings, so the more structure it has to fabricate, the more obvious the repair becomes.
- Large objects occupying a significant part of the frame
- Anything overlapping a face, or a person you want to keep
- Objects sitting across strong patterns, reflections or straight architectural lines that need to continue convincingly
- Removals where the background behind the object was never visible anywhere in the image
For those, the AI options are the better route - AI Edit can regenerate a region from a text prompt rather than merely patching it, which handles complex structure far better than inpainting can.
Free and premium methods
- OpenCV inpainting - free, fast, and good for the small and simple cases above. The default.
- AI object removal - 5 credits, noticeably more seamless on awkward backgrounds. Worth it when the free pass leaves a smudge.
Your 20 free signup credits cover 4 AI removals.
Getting a clean result
- Brush slightly beyond the object's edge. Leaving a rim of the original behind is the most common cause of a visible halo.
- Remove several small things in separate passes rather than one large selection - each pass has more clean surrounding pixels to draw on.
- Work at a sensible zoom so your brush is accurate near edges you want to keep.
- If a free pass leaves a smear, undo and retry with the AI method rather than brushing over the same spot repeatedly.
Step by step
- Open the editor and load your image, then choose Object Removal from the Background panel.
- Zoom in far enough that you can brush accurately - the zoom controls sit at the bottom of the canvas, and the scroll wheel zooms toward your cursor.
- Paint over the object, extending slightly past its edge on every side.
- Run the removal, then inspect at 100% rather than fit-to-screen. Problems that are invisible when the image is scaled down show up clearly at full size.
- If the patch looks smeared, undo and either reduce the area or switch to the AI method.
A note on watermarks
Clearing the visible watermark from an image you generated yourself is a normal editing task. Removing a watermark from someone else's copyrighted photograph to reuse it is not - that is a matter of their rights, not of what the tool can do.
