What does "remove the background" actually produce?
An image whose background pixels are transparent: their alpha channel is zero, so whatever sits behind the image (a page, a T-shirt, a slide) shows through. A JPG cannot hold transparency, so the result is either a PNG with an alpha channel or an SVG, where the background simply is not drawn. The edge pixels matter most. A good cut-out keeps soft edges soft and does not leave a pale halo of the old background around the subject.
Which mode should I use, Flat background or Subject (AI)?
The background remover has two modes. It picks one for you from the image you drop (Flat background for a plain backdrop, Subject (AI) for a photo), and you can change it. Subject (AI) is offered while its service is on; otherwise the remover works in Flat background only.
| Mode | How it decides what is background | Use it for |
|---|---|---|
| Flat background | everything connected to the image's edges in the backdrop's colors, removed from the edges inward; exact, with no guessing | logos, icons, stickers, screenshots and illustrations on a plain or nearly plain backdrop |
| Subject (AI) | the main subject of the picture, found by an AI model | photos and scenes where the background is busy, textured or several colors |
Flat never removes an enclosed area, even when it is the same color as the backdrop. The white of an eye, the inside of an "O" and a white highlight stay, because they do not touch the edge. That is usually what you want for flat artwork, and it is the reason to prefer Flat whenever the backdrop is plain. Flat also clears a baked-in transparency checkerboard, the gray and white squares some images carry instead of real transparency.
One of our example logos through the background remover in Flat mode: the original, the transparent PNG and the SVG. The white of the eyes stays, because it does not touch the edge.
PNG or SVG: which result do I want?
The remover's result is a transparent PNG. Keep it to keep the image as it is, with its photographic detail, texture and soft shadows, and only lose the background. The PNG comes back at the uploaded size (very large images are scaled down first), with soft alpha on the edges and the edge colors recalculated without the old backdrop, so no white fringe is left.
For an SVG, choose Vectorize the cut-out on the result: worth it when the artwork is flat color and you want vector paths, such as a logo for a website, a cut file or an icon to recolor. The cut-out is traced; the SVG has no background box at all. For photos, an SVG turns gradients into flat areas (see why photos posterize), so a photo's subject is better kept as PNG.
How do I do it?
- Open the background remover and upload a PNG, JPG, WebP or HEIC.
- Keep the mode it picked, or choose Flat background or Subject (AI).
- Look at the watermarked preview over the checkerboard. Check the edges, the gaps between arms or letters, and any white details you need to keep.
- Unlock the clean result. Its price is stated before you unlock, and a failed run is never charged.
- For vector paths, choose Vectorize the cut-out on the result.
If Flat leaves a strip of backdrop around the edge (a shadow or a vignette that is not one color), switch to Subject. If Subject eats into a white detail that belongs to the subject, switch to Flat or fix the detail afterwards in the SVG editor.
Can I use the cut-out commercially?
You keep whatever rights you already had in the image. Removing a background does not change who owns a photo or a logo, so make sure you may use the original. For a product photo or a portrait, also check the store or platform rules for transparent images. Some marketplaces require a white backdrop, not transparency.
