How to use Convert Base64 to PNG
- 1. Paste the Base64 string. Paste the encoded text into the input pane. It works whether you paste a bare Base64 string or a full data: URI with the prefix included.
- 2. Let the tool decode it. The tool strips any data URI prefix, decodes the Base64 text back into raw bytes, and validates that those bytes form a proper PNG file.
- 3. Download the recovered PNG. Save the resulting image file, ready to open, view, or drop straight into a design tool or web page.
When to use Convert Base64 to PNG
Convert Base64 to PNG decodes an encoded string back into a downloadable image file. It is the tool you need whenever a PNG has been embedded as text, for example inside JSON, source code, or an email, and you need the actual file back.
- Extracting an image from an API payload. An API response embeds an image as a Base64 field instead of a URL, and decoding it here gives you the actual PNG file to inspect or save.
- Recovering an image from source code. A codebase has a PNG hardcoded as a Base64 constant for inlining, and decoding it lets you view or edit the actual image behind that string.
- Restoring an image from a database dump. A database export stores an uploaded image as a Base64 column value, and decoding it recovers the original file for verification or reuse.

About the Convert Base64 to PNG tool
Convert Base64 to PNG runs as plain JavaScript in your browser tab, with no server behind it. Decode a Base64 string back into a downloadable PNG file. Whatever you put in stays on your device from start to finish.
The tool is part of EditSafely's PNG Tools section, 108 single-purpose utilities built around the same idea: open the page, get the result, keep your data to yourself.
There is nothing to configure. Provide the input and the result appears on its own. The finished file is put together in browser memory and saved with the Download button, so it never touches a server on the way to your disk. A worked example further down the page shows exactly what the tool produces for a real input.
That local-first design has practical benefits beyond privacy. The tool keeps working on a flaky connection once the page has loaded, results are instant because nothing round-trips to a server, and it is safe to use with confidential material.
Frequently asked questions
Does Convert Base64 to PNG cost anything?
Yes, it is completely free. All 2,658 tools on EditSafely work without an account, a subscription or usage limits.
Is it safe to paste sensitive or confidential data?
No data leaves your device. The whole tool is JavaScript that runs inside your browser tab, so there is no upload, no server-side processing and no log of what you did. If you disconnect from the internet after the page loads, it keeps working.
How much text can I process at once?
There is no fixed limit. Because the work happens on your own device rather than on a shared server, the practical ceiling is your machine's memory, which comfortably handles inputs far larger than typical online tools allow.
Do I need to sign up or install anything?
Nothing to install and no account needed. Open the page in any up-to-date browser, including on a phone or tablet, and the tool is ready.
How do I save the output?
