Does it need the data: prefix?

For best results include the full 'data:image/...;base64,' prefix; we'll add a PNG prefix if missing.

Where would I find a Base64 image string to decode?

Common sources include CSS background-image properties, inline <img> src attributes, JSON API responses, or embedded assets found while inspecting a webpage's source code.

What image formats does this support?

It works with standard web image formats like PNG, JPG, and WebP, decoding whatever format is specified in the data URI's prefix (or defaulting to PNG if that prefix is missing).

Will the decoded image match the original exactly?

Yes — Base64 encoding and decoding is lossless, so the decoded image is pixel-for-pixel identical to whatever was originally encoded, with no quality loss from the conversion process.

Is my pasted data uploaded anywhere?

No — the entire decoding process happens locally in your browser, so the data URI you paste never leaves your device.

Can I use this to check if a Base64 string is actually a valid image before using it in code?

Yes — pasting it here and seeing whether a preview renders correctly is a quick way to confirm the data URI is valid and represents the image you expect, before embedding it elsewhere.
