Remove Background from Image Online Free
Background Remover lets you remove the background from an image online free — upload a photo and an in-browser AI model isolates the subject and clears the background to a true transparent PNG. There is no watermark, no sign up, and no upload: your photo never leaves your device. Keep the cutout transparent, or drop it onto a white, black, or custom-colour background before you download.
Ready to cut out your subject? It takes one tap.
Use the free background remover →How It Works
This is a free AI background remover that runs entirely in your browser. When you choose an image, a machine-learning segmentation model loads on your device and predicts which pixels belong to the subject and which belong to the background. The background pixels are made transparent, and the result is composited onto an HTML canvas and exported as a real PNG with an alpha channel.
Because the model runs locally, your photo is never uploaded to a server. The only download is the AI model itself, the first time you use the tool — after that it is cached, so removing a background using AI for free is near-instant on every later visit, even offline.
How to Remove a Background from Your Image
The whole flow takes two screens and works the same on desktop, iPhone, and Android:
- Open capsuletools.app/background-remover/
- Tap the dropzone and choose a JPG, PNG, or WebP (or paste a copied image)
- Wait a moment while the AI removes the background — you will see the subject on a transparency checkerboard
- Optionally pick a background colour (transparent, white, black, or a custom hex), nudge the Refine edges slider to kill halos, or use the Touch up brush to erase or restore detail by hand
- Tap Download transparent PNG to save the cutout (
[filename]-cutout.png)
Supported Formats and File Size
You can upload JPG, PNG, or WebP images up to 15 MB. The cutout is kept at a high resolution so the downloaded file stays sharp, and the export is always a transparent PNG — the only common format that can store a transparent background. If you composite the subject onto a solid colour instead, that also saves as a PNG.

What Makes This Background Remover Different
Most "background remover" sites upload your image, then add a watermark, drop the resolution, or ask you to buy credits before you can download. This transparent background maker is free with no watermark and no sign up, and nothing is ever transmitted because the work happens in your browser tab.
You also get controls most one-click tools hide: the edge-refine slider chokes or spreads the mask to clean up stray pixels and halos, and the manual brush lets you erase leftover background or restore a piece of the subject the AI trimmed too aggressively — so a near-miss becomes a clean cutout without opening Photoshop.
Frequently Asked Questions
Is this background remover really free with no watermark?
Yes. It is completely free and never adds a watermark to your image. Many background removers stamp a logo on the result or blur it until you pay — this one does not. You get the full-quality transparent PNG with nothing added, no trial, and no credits to buy.
Does this tool work on iPhone and Android?
Yes. It runs in any modern mobile browser, so you can remove a background from an image on iPhone or Android with no app to install. Open the page in Safari or Chrome, choose a photo from your camera roll, and download the transparent PNG straight to your phone. You can also add it to your home screen to use it like a native app.
Do I need to sign up or create an account?
No. There is no sign up, no account, and no email required. Open the page and start removing backgrounds immediately. Because everything runs in your browser, there is nothing to register for.
Is my photo uploaded to a server?
No. Your photo never leaves your device. The AI model runs entirely in your browser, so the image is processed locally on your phone or computer. The only thing downloaded is the model itself, once, which is then cached for next time.
How do I get a high resolution transparent PNG?
Upload your image at full quality — the tool keeps the cutout at the same resolution it processes, up to a large working size, so the downloaded PNG stays sharp. The export is a true transparent PNG with a real alpha channel, not a flattened JPEG or a fake checkerboard, so it drops cleanly into any design, slide, or product listing.
How do I make an image background transparent online for free?
Open the tool, choose your image, and the AI clears the background to transparency automatically. Leave the background set to Transparent and tap Download to save a transparent PNG. If you would rather swap the backdrop, pick a white, black, or custom colour before downloading.
Can I remove the background from an image using AI for free?
Yes. This is a free AI background remover. It uses an in-browser machine-learning segmentation model to detect the subject and cut away the background in one tap — no cost, no watermark, and no upload. If the AI misses an edge, you can refine it or touch it up by hand.
What image formats are supported?
You can upload JPG, PNG, and WebP images up to 15 MB. The output is always a PNG so the transparency is preserved — JPEG cannot store a transparent background. If you composite the subject onto a solid colour instead, that also exports as a PNG.
