Quickstart

To remove the background from a photo, open the AI Background Remover, drop the photo on the page, check the edges with the slider, and click Download. You get a transparent PNG the same size as the photo. The whole thing runs client-side, so the photo is never uploaded.

How do I remove a background from a photo, step by step?

1. Add the photo. Drag it anywhere onto the page (not only onto the box), paste it with Ctrl V or ⌘ V, or press Ctrl O / ⌘ O to open the file picker. No photo to hand? Click one of the four sample thumbnails under the drop zone.
2. Wait for the cutout. The photo appears straight away and a small "Removing background" pill sits over it while the model works. On a computer with WebGPU that is usually one to three seconds; on the processor path, expect 10 to 30.
3. Check the edges. The preview opens in Compare mode: the original on the left of the divider, the cutout on the right. Drag the divider across hair and fine edges, or hold Space to see the whole original for a moment.
4. Save it. Click Download PNG, or Copy to put the cutout on the clipboard for pasting into a document or chat. The file is named after your photo with -no-bg added, so sofa.jpg becomes sofa-no-bg.png.

That is the default output: transparent background, original size, PNG. Everything in the panel on the left (background, size, crop, upscale, format) is optional and is covered in Backgrounds and Resize, crop and AI upscale.

Tip. A halo that is invisible on the checkerboard shows up at once on black. Pick Color, then the black swatch, and slide the divider along the hairline before you download.

Why does the first photo take longer?

The first time you use the tool, the browser downloads the AI model: about 98 MB for the GPU model or 46 MB for the processor model. The page starts that download quietly as soon as it opens, so it is often done before you pick a photo. After that the model sits in the browser's cache and later photos, and later visits, skip the download.

Two cases skip the early download on purpose. If your browser has Data Saver turned on, or reports a 2G or 3G connection, the page waits until you add a photo rather than spend 98 MB you did not ask for. A model that is already cached always loads, since that costs no network.

How do I make a picture's background transparent without a watermark?

Leave Background on None and Format on PNG or WebP, then download. Both formats store an alpha channel, so the area around the subject is saved as fully transparent pixels. There is no watermark, no reduced preview size and no credit system. If you pick JPG, the background is saved white instead, because JPEG has no transparency. File formats explains the difference.

Can I remove a background on an iPhone or Android phone?

Yes. Open the tool in Safari, Chrome or any mobile browser, tap the drop zone and choose a photo from your library. iPhone HEIC photos are read directly, no conversion needed. Phones always get the smaller processor model, which keeps the download to 46 MB and stays inside a phone tab's memory budget, so each photo takes longer than on a computer.

On iOS 16 and later, the Photos app can also lift a subject off its background: touch and hold the subject, then choose Copy or Share. That works well for a quick sticker. Use the Toolz.dev tool when you want a file at full resolution, a new background, a fixed output size, or a batch of photos done the same way.
