How it works
Paste a Base64 string or data URI, click Convert to image, and the tool decodes the text back into the original binary data — downloaded as a ready-to-use image file.
Base64 to Image
Paste a Base64 string or data URI and download it as an image — no sign-up, no upload, no file size limit.
Your files never leave your device. Everything runs locally in your browser — nothing is uploaded to a server, so there's no file size limit, no subscription, and no one but you ever sees what's in your file.
Frequently asked questions
What format should I paste?+
Either a full data URI (starting with data:image/...;base64,) or a raw Base64 string with no prefix. If you paste a raw string, use the format dropdown to tell the tool what kind of image it is — that's needed since a raw Base64 string has no built-in format information.
Why did I get an error decoding my text?+
The text needs to be valid Base64 — check that you copied the whole string with nothing missing or extra (like surrounding quote marks) added by accident.
Is the output an exact copy of the original image?+
Yes — decoding Base64 just reconstructs the original bytes exactly, so the output file is byte-for-byte identical to whatever was encoded.
Is my data uploaded anywhere?+
No. This tool runs entirely in your browser using JavaScript — the text you paste is decoded and downloaded without ever being sent to a server.
Keep a backup of your original file. This tool processes everything locally in your browser, and we've tested it carefully — but no conversion tool handles every PDF perfectly. Always keep your original file and double-check important results before relying on them.
