Transparent background
Drop in a photo and the background comes away, leaving the subject on transparent pixels. The file you get is a PNG with a real alpha channel, so it drops onto any colour or any slide without a white box around it.
The work happens on your own device. Nothing is uploaded.
Drop a photo here, or
JPG, PNG and WebP, up to five at once. They stay on your device.
Questions
- Is my photo uploaded?
- No. The photo is read from your disk, worked on inside the browser tab, and saved back to your disk. There is no server here that could receive it. The one thing that does cross the network is the model itself, coming in the first time you use the tool, and you can watch that in your browser's network tab: model files arrive, no image leaves.
- Will it really be transparent, or just white?
- Really transparent. The saved file is a PNG whose alpha channel is written from the cutout, and the tests decode that channel out of the encoded bytes to check it rather than trusting the file extension. Put it on a coloured slide and you will see the difference immediately.
- How good are the edges on hair?
- Hair and fur are the hard part of this problem and no automatic tool gets them perfect. Fine strands against a busy background are where it struggles most. That is why the result is shown zoomed in on an edge before you download: judge it there rather than after you have used the file somewhere.
- Can I do several at once?
- Up to five in one go. They run one after another rather than together, because the model is large and several passes at once is how a phone browser runs out of memory.
- Why is my file bigger than the photo I started with?
- PNG is lossless and carries a fourth channel for transparency, where a JPG is lossy and carries three. That combination usually costs more bytes. It is the trade for having transparency at all, since JPG cannot store it.
