Remove Background

Remove the background from any photo, privately

This free tool will remove the background from a photo and give you a transparent PNG: a portrait for a profile picture or CV, a product shot for an online shop listing, a pet, a logo photographed on a table. An AI model finds the subject, a set of refinement steps cleans up the edges, and a brush lets you fix anything the AI got wrong.

Unlike most background removers, nothing is uploaded. The AI runs inside your browser using WebAssembly, so your pictures stay on your phone or computer — which matters for ID photos, children and unreleased products. The only download is the model itself, and your browser keeps it for next time. You can process several photos in one go and save them all as a ZIP.

How to use the Remove Background

1. Choose an AI model: “People & portraits” for people, “Products & objects” for things, pets and full-body shots.
2. Drop one or more photos on the upload box (or paste with Ctrl+V). The first time, the model downloads with a progress bar.
3. Check the result on the checkerboard. Drag “Before / after” to compare with the original, and adjust “Edge softness” or “Shrink / grow edge” if needed.
4. To fix mistakes, pick “Erase” and paint over leftover background, or “Restore” and paint over parts of the subject that went missing. Undo steps back one stroke.
5. Press “Download PNG”. With several photos, click each one in the list to check it, then press “Download all (ZIP)”.

How the background is removed

Each model reads a reduced copy of your photo and predicts, for every pixel, how likely it is to belong to the subject. The result is an alpha matte: white for subject, black for background and greys in between for hair, fur and motion blur. The tool scales that matte up to your photo and removes stray specks. For the two smaller models, whose masks are coarser, “Snap edges to the photo” (on by default for them) runs a guided filter (He, Sun and Tang) that pulls the edge onto the real edges in the picture. Finally, edge colours are cleaned with a fast foreground-estimation method (Forte and Pitié), so wisps of hair carry no trace of the old wall when you put them on a new background.

What works well and what doesn’t

• Good: one clear subject, in focus, that stands out from the background — a person against a wall, a product on a table, a pet on grass.
• Hair and fur: MODNet keeps loose strands as partial transparency; on busy backgrounds some strands may vanish or keep background colour. Try “Shrink / grow edge” and the brush.
• Similar colours: black hair on a dark background or a white shirt on a white wall can be cut too tightly or not enough. Restore or erase those parts by hand.
• Glass, smoke and transparent objects are treated as solid or removed; true see-through cut-outs need manual editing.
• Several subjects: people models keep everyone; the object model favours the most prominent thing. Erase what you don’t want.
• Full-body shots: MODNet is trained on portraits and can lose legs or feet — switch to “Products & objects”.

After the cut-out

A transparent PNG is ready for slides, documents, stickers and design tools. To put the subject on a plain colour for a passport, ID or marketplace photo, use Change Background Color; to place it on a new scene or gradient, use Change Background; to keep the scene but soften it like a portrait-mode camera, use Blur Background. Image Shadow adds a soft drop shadow so a product doesn’t look pasted on.
