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 the cutout kept, and it is worth a glance. Under 2%, the page says it found no clear subject, and the file you save will be nearly empty. Over 98%, it says it removed almost nothing. Both are quicker to spot in a figure than in a small picture.

There is no brush here, 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
RMBG-1.4 by BRIA AI, about 44 MB. BRIA lets anyone use it for free as long as it is not for profit. Your browser keeps it 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, products and pets that stand out from what is behind them. 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 page reads the photo and never sends it 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 and the code that runs it. Your browser keeps both, so the next photo starts straight away and nothing more downloads.
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. Fine strands and low contrast edges are the hard case for any cutout. 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 the page paints it behind the cutout. Choose Keep it transparent to keep the clear background 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 page crops off the clear margin around it, 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?
The model learned from photos of people, products and animals, so most clear subjects work. 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.
