Transparent Background Online — Free, Fast & Private

A transparent background lets you place an image on any color, gradient, or scene without an ugly white box around it. MiniPx makes any image transparent online for free, and the AI does it in your browser — no upload, no signup, no quota.

The output is a standard transparent PNG (RGBA format with the alpha channel set per the AI-detected subject mask). Drop it straight into Shopify product listings, Etsy storefronts, Notion docs, slide decks, Figma designs, or anywhere else a transparent image is needed.

JPEG files cannot hold transparency by design — that is why the output is always PNG. If you need a transparent image saved as a different format (WebP supports transparency, AVIF does too), use the converter on the result.

For the interactive tool, head to the Background Remover. For passport-style transparent-on-white photos, see Passport Photo Maker.

Frequently asked questions

What is a transparent background?

It is an image where the area around the subject has no color, so whatever is behind the image shows through. Useful for logos, product photos, profile pictures, and design composites.

Why PNG and not JPEG?

JPEG cannot store transparency. PNG, WebP, and AVIF all support it. MiniPx outputs PNG by default.

Is it really free?

Yes. Free tier outputs 1080x1080 with a tiny "minipx.com" watermark. No signup, no quota.
