Background

PNG and WebP both keep the clear background. WebP is smaller. The mask is just the shape, for fixing edges in another app.

How it works

  1. 01

    Add a photo

    Drop, paste or pick one image. The first cutout also fetches the model, which takes a moment.

  2. 02

    Watch it come off

    The cutout wipes across the photo it came from. The page prints how much of the frame it kept.

  3. 03

    Pick a background and save

    Keep it clear, or set a colour behind the subject. Save a PNG, a WebP, or the mask on its own.

Where automatic cutouts struggle

A cutout is a guess about which pixels are the subject. That guess is good when the subject stands clear of what is behind it, and poor when the two share colours. Hair, fur, glass and loose fabric hold background between fine details, so the edge there is a judgement call rather than a line.

The number under the preview is the share of the frame that was kept. It is worth a glance. If it says 3%, the model found no subject and the file you save will be nearly empty. If it says 97%, it removed almost nothing. Both are quicker to spot in a figure than in a small picture, which is why the page prints it.

There is no brush here yet, so an edge this tool gets wrong stays wrong. Save the PNG and fix it in an editor, or try a photo where the subject is clearer. The mask export exists for the same reason: it hands the shape to a tool that does have a brush.

Model
ormbg, about 42 MB. Free to use for any purpose, and kept in this browser after the first run.
Speed
A second or two with a GPU. Without one it runs on four CPU cores, which takes longer.
Output
PNG or WebP with real transparency, or the mask as a grey image. Full size, no mark added.
Best with
People, and any subject that stands out from what is behind it. One image at a time.

Frequently asked questions

Is my photo uploaded to remove the background?
No. The model runs in this tab, on your own machine. The photo is read by the page and never sent to a server. You can turn off your network after the model has loaded and it still works.
Why is the first cutout slow?
The first one has to fetch the model. Your browser keeps it after that, so the next photo starts straight away. Nothing else is downloaded while you use the tool.
Is the result watermarked or made smaller?
No. You get the same width and height you put in, with no mark on it. There is no daily count and no sign-up.
The edge around hair is wrong. Can I fix it?
Not in this tool yet. Fine strands and low contrast edges are the hard case for any cutout. For now, save the PNG and touch it up in an editor, or try a photo where the subject stands out more.
Can I put a colour behind the subject?
Yes. Pick a colour before you save and it is painted behind the cutout. Leave it clear to keep the transparency instead.
What is the mask for?
It is the shape of the subject as a grey image: white where the subject is, black where the background was. Editors take it as a layer mask, so you can do the mixing there.
Can I crop the empty space away?
Yes. Turn on Trim to the subject. The clear margin around it is cropped off, so the saved file is only as big as the subject itself. Leave it off to keep the size you put in.
Which subjects work best?
People work best, because that is most of what the model was trained on. Products and pets usually work when they stand clear of the background. A busy scene with no obvious subject will not.
Can I do a whole folder at once?
No. One image at a time, because each one holds the full picture in memory twice while it is worked on. A batch would run a phone out of room.
Why does WebP give a smaller file than PNG?
PNG stores every pixel exactly, which costs space. WebP keeps the transparency but packs the colour more tightly. Pick WebP for the web and PNG when you need an exact copy.
Is there a size limit?
Yes, one: 40 megapixels. That is above any phone or camera in normal use. Past it, the tab would run out of memory instead of finishing, so the page says no rather than crashing.
