Paint over the thing you don't want (a photobomber, a bin, a stray cable) and BGNinja's ✨ Magic erase fills in the background behind it, like it was never there. Free AI inpainting, in your browser, no sign-up and no watermark.
Erase something now →Switch the tool to ✨ Magic erase, brush a red mark over the object or person, and hit Erase it. An AI inpainting model (LaMa) reconstructs the background behind your selection (grass, sky, wall, pavement), so the photo stays whole instead of getting a hole. It takes a few seconds per pass, and you can keep going: erase one thing, then paint over the next.
Honest limits: the fill is a reconstruction, not magic. It shines on reasonably simple backgrounds: skies, walls, grass, water, blur. Very detailed or busy scenes (crowds, text, patterns, complex architecture) can come out with visible artefacts, and the larger the area you erase, the more the AI has to invent. If a first pass leaves a smudge, paint over the leftover and run a second pass. That usually cleans it up.
Switch to ✨ Magic erase and drop in any JPG, PNG or WEBP.
Brush a red mark over the object or person. Resize the brush for fine edges; Clear selection restarts the mark.
Hit ✨ Erase it: the AI fills in the background in a few seconds. Repeat for anything else, then download your PNG.
Almost everything people erase falls into one of three buckets, and the same paint-and-fill flow handles all of them (only the difficulty changes with the background behind it).
The most common ask: one stranger wandered into an otherwise perfect shot, or you want to trim a group photo down to the people who should be in it. Paint over the person and Magic erase rebuilds the background where they stood. This is easiest when the space behind them is calm (a beach, a wall, grass, sky) and hardest when they overlap another person or a detailed pattern. Two honest tips make a real difference: paint their shadow and any reflection too, not just the body, or you'll leave a giveaway on the ground; and if a first pass leaves a smear, paint over the leftover and run it again. A person is a large area to reconstruct, so a second pass is normal rather than a sign it failed.
Bins, road cones, signs, cables, a stray car or a prop that sneaked into a product shot: these are usually smaller than a person and sit against simpler surroundings, so they're the most reliable case of all. Brush over the object, erase, done. The smaller and more isolated the thing, and the plainer the surface behind it, the closer to invisible the fix.
Date stamps, captions, logos and watermarks come off the same way: paint over the text and the AI fills in whatever was behind it. It works best when the mark sits on a fairly even background (a sky, a wall, an out-of-focus area) and struggles when the text lies over fine detail or busy texture, where the reconstruction has more to invent. One fair-use note: only remove text or watermarks from images you own or have permission to edit. To keep the file's own transparency instead of filling a solid area, the cutout side of the tool is on the background remover.
Magic erase keeps the whole scene and fills the gap. Sometimes you want the opposite: only the subjects, on a transparent background. For that, use ✂ Remove background mode: BGNinja cuts your photo into a transparent PNG, and the 🩹 erase brush lets you trim away any subject or stray edge you don't want (those pixels become transparent; nothing is painted in behind them). The ↩ restore brush brings anything back. Two routes, one tool (pick whichever matches the result you're after).
Upload your photo, switch to ✨ Magic erase, paint over the object or person and hit Erase it: the AI fills in the background behind it in a few seconds. Free, no account, no watermark.
Yes. In ✨ Magic erase mode, paint over the person and the AI reconstructs the background where they stood. It works best when the scene behind them is reasonably simple: a second pass tidies up any leftovers.
Yes, in ✨ Magic erase mode the AI paints in the background behind whatever you remove (LaMa inpainting). Very complex or detailed scenes can show small artefacts. In ✂ Remove background mode the erase brush works differently: erased areas become transparent instead, which is what you want when you're keeping only certain subjects.
Yes, in two quick steps: erase the objects first in ✨ Magic erase and save the result, then run that photo through ✂ Remove background for a transparent PNG.
Yes — paint over the text or mark and the AI fills in the background behind it. It works best when the mark sits on an even background and struggles over fine detail. Only remove text or watermarks from images you own or have permission to edit.
It can, if you don't paint it. For a clean result, brush over the person's shadow and any reflection as well as their body, then erase. A second pass tidies up anything the first one missed.
No. Your photo is processed and deleted straight away: nothing is stored or used to train anything.
