Turn a plain white or solid-colour background transparent and download as a PNG — fully client-side, nothing ever uploaded.
This tool detects a plain, near-uniform background — white paper, a solid studio backdrop, a flat logo canvas — and converts it to a fully transparent PNG right inside your browser, with nothing ever sent to a server.
Works best with a signature, logo, stamp, or product photo shot on a plain white or solid-colour background.
The background color is auto-detected from the image corners and converted to transparency, with a smooth, anti-aliased edge around your subject.
Your result exports as a lossless PNG with a true alpha channel, ready to drop into any website, document, or design tool.
Everything you need to know about this developer tool
It works best on images with a plain, near-uniform background — a signature or stamp scan, a logo, or a product shot on a white/solid backdrop. It is not built for removing a busy, complex photographic background from a portrait; that needs a different, AI-based approach.
No. The entire conversion happens locally in your browser using the Canvas API — your image is never uploaded anywhere.
A PNG file. PNG is the only common format that losslessly stores a true transparent (alpha) channel, so the output format is fixed to PNG automatically.
The tool detects the background color by sampling the four corners of your photo. If your image has uneven lighting, a shadow, or the subject touches the corners, the detected color may be slightly off — try a more evenly lit scan or photo for the cleanest cutout.
