Remove a white background online free
White pixels turn transparent instantly — perfect for logos, stamps and signatures. No neural net, no soft edges.
Perfect for flat graphics
Remove a white background in 4 steps
A logo, stamp, signature or scan — JPG or PNG up to 12 MB.
White and near-white pixels turn transparent; semi-tones fade smoothly.
Thresholding doesn't blur contours — lines stay razor sharp.
Ready for dark layouts, colored banners and documents.
Part of the Zerocoder platform
One tool of a platform where AI generates websites, images, video, text and documents — under one subscription.
A white backing stops a logo from sitting on colored layouts and a stamp from joining a digital document. For flat graphics, threshold-based removal beats a neural net: edges stay sharp and processing is instant. For photos use neural background removal; for black backings — black removal. Upscale tiny logos first with image upscaling. All free tools live in one section.
Stamps and signatures for digital documents
A scanned stamp or signature can't go into a contract with a white box around it — it looks sloppy and covers text. Run the scan here: white turns transparent, the ink stays. The PNG drops into Word, PDF and Google Docs over any text. For pale scans, lift the contrast first with image enhancement.
A white-backed logo onto any layout
Designers deliver logos on white; you need them on dark and colored. Thresholding produces a perfectly clean edge without the halo neural nets sometimes leave on flat art. White elements inside the logo turn transparent too — that's inherent to the method; if that's a problem, use the neural variant.
Threshold vs neural net
Thresholding is pure math: pixels lighter than the cutoff go transparent. No latency, no model guesswork, no distorted lines. Its weak spot is photos and gradient backdrops — segmentation wins there. Simple rule: flat art on plain white — here; everything else — the neural tool.

FAQ
Why is this better than a neural net for logos?
A precise color threshold keeps lines crisp and fires instantly. On flat graphics the result is cleaner.
What if the logo contains white elements?
They turn transparent too — the method can't tell background from content. Use the neural “Remove background” for those.
Good for stamps and signatures?
Yes — the core use case: the white scan turns transparent, ink stays, the PNG drops into any document.
Do I need an account?
Your first result needs no account. After that we ask for a free sign-up: signed-in users get 5 runs per day, and the Zerocoder Studio has no limits.
What about my files?
Never stored: in-memory processing, instant return.
Why are the edges so sharp?
Semi-tones between white and color become smooth partial transparency — no jaggies, no blur.
Will grey backgrounds vanish too?
Light grey close to white — yes, smoothly. Dark grey stays: the threshold targets white.
What's the output format?
An alpha-channel PNG at the original resolution up to 3000 px per side.
What else can Zerocoder do?
Website, image, video and text generation under one subscription. This tool is the free part.
