Background Remover

AI Background Remover

Remove the background from any image free and get a transparent PNG — then change the background, add a shadow, text or blur. 100% in your browser: your images never leave your device. No sign-up, no watermark.

We use a machine learning model that runs entirely in your browser via WebAssembly. It detects the foreground subject and creates a transparent PNG. No images are sent to any server.

No. All processing happens locally in your browser. Your image never leaves your device.

Supports JPG, PNG, WebP — up to 20 images at once, max 20 MB each

Why Background Remover?

AI-powered, private, instant — remove backgrounds from any photo with one click.

AI background removal

An in-browser AI model detects the subject and cuts out the background, giving you a clean transparent PNG in seconds.

Private — no upload

Everything runs locally with WebAssembly. Your photos are never sent to a server, so confidential product shots and personal images stay on your device.

Full editor, not just a cutout

Refine edges with the eraser, soften areas with the blur brush, flip the subject, then scale, rotate and move it freely.

Change or replace the background

Drop in a solid color or upload your own background image, add a drop shadow with adjustable blur and opacity — perfect for product photos and thumbnails.

Add text & compare

Place multiple text layers (17 fonts, color, bold, italic) anywhere on the image, and use the before/after slider to check your result.

Free, unlimited, batch

No sign-up, no watermark, no daily limit. Process up to 20 images at once and download them all as a ZIP.

How AI background removal works

An ONNX model + WebAssembly = subject-detection AI in your browser.

  1. 1

    First load downloads the model (~7 MB)

    On first use, the browser downloads a quantised ONNX segmentation model — about 7 MB compressed. After the first load it's cached, so subsequent runs are instant. The model never leaves your device after download.

  2. 2

    ONNX Runtime executes the model

    onnxruntime-web runs the model using WebAssembly (with WebGPU fallback on supported browsers). The model takes the image as input and outputs an alpha mask — a grayscale image where white = subject, black = background.

  3. 3

    Mask applied to the original

    We composite the mask onto the original via an OffscreenCanvas, producing a transparent PNG where the background is fully transparent. The output is bit-identical to what a Python pipeline using the same model would produce — the difference is just "in your browser" vs "on a GPU server".

  4. 4

    Download or batch up to 20 images

    Single output downloads directly as a transparent PNG. For a batch (up to 20 images) we run them sequentially and bundle the results into a ZIP. Total processing time depends on image resolution — typically 1-3 seconds per image on a modern laptop.

Real workflows for cutouts

Where browser-side AI matters most.

E-commerce product shots

Drop 10 product photos with messy studio backgrounds, get 10 clean cutouts on transparent PNG. Pair with iKit's image compressor to deliver them at 50% file size for product listings.

Profile photos for LinkedIn / dating apps

Strip the background and drop in a solid colour or new scene. Your face never lands on remove.bg's servers, where (as their privacy policy admits) it might be used for model training.

Social media stickers

Cut out a friend, a pet, or a meme subject for use as a sticker in chat apps. Transparent PNG drops straight into Telegram / WhatsApp / Discord.

Confidential subjects

Internal product prototypes, unreleased designs, NDA-bound subjects — anything that absolutely cannot be uploaded. iKit's model runs locally, so the photo never leaves your tab.

Why this matters for AI tools

Most AI background removers are server-side: your photo goes to their GPU, their model runs, the result comes back. The photo sits in their storage long enough to be cached, logged, and (per most ToS) used for model improvement. iKit runs the entire model in your browser via WebAssembly — nothing about your image is ever transmitted.

  • ONNX model runs locally — no API call, no GPU server.
  • First-load model is cached, so subsequent runs work offline.
  • Photos and outputs never persist on any server.

Frequently Asked Questions

How does the background removal work?

We use a machine learning model that runs entirely in your browser via WebAssembly. It detects the foreground subject and creates a transparent PNG. No images are sent to any server.

Is my image uploaded anywhere?

No. All processing happens locally in your browser. Your image never leaves your device.

What image formats are supported?

You can upload JPG, PNG or WebP images up to 20 MB. The output is always a transparent PNG.

Is there a limit on how many images I can process?

No. Since all processing happens in your browser, there is no server-side limit. Process as many images as you want.

Why does it take a few seconds on the first image?

The AI model (~40 MB) is downloaded and cached in your browser on first use. Subsequent images are processed much faster.

Is this background remover really free, with no watermark?

Yes — completely free, no sign-up, no watermark and no daily limit. Unlike tools that give a few free credits or add a watermark, you can remove backgrounds from as many images as you want.

How do I change or replace the background of a photo?

After the background is removed, pick a solid color or upload your own background image. You can also add a drop shadow so the subject sits naturally on the new background.

How do I make an image background transparent (PNG)?

Remove the background and download — the result is a transparent PNG with a real alpha channel (no white box), ready for slides, stickers, logos and design mockups.

Can I remove backgrounds from multiple images at once?

Yes. Add up to 20 images, process them in one go, and download all the transparent PNGs together as a ZIP file.

Do my images get uploaded to a server?

No. The AI model runs entirely in your browser via WebAssembly, so your images never leave your device — verifiable in DevTools → Network (no upload request during removal).
