How to use Base64 Decode PNG
- 1. Paste the encoded PNG text. Put the Base64 string into the input pane. PNG data characteristically starts with iVBORw0KGgo, and pasting a complete data URI with its data:image/png;base64, prefix works just as well.
- 2. Check the decoded preview. The bytes are reconstructed and rendered immediately, transparency included. If the preview looks wrong or fails, the string was likely truncated when copied, which is the most common failure.
- 3. Download image.png. Save the recovered file with one click. It is a standard PNG, so it opens in any viewer and can go straight into another EditSafely tool for resizing or conversion.
When to use Base64 Decode PNG
Base64 Decode PNG reverses the text encoding and gives you back a real PNG file. Encoded PNGs hide everywhere in modern development: inline CSS backgrounds, favicon fields, API fixtures, clipboard dumps and test snapshots. Whenever you are staring at iVBORw0KGgo and need to see the picture, this is the tool.
- Seeing an inline CSS or HTML image. A stylesheet embeds a background as a data URI and you need to know what it depicts. Paste the URI and the decoded PNG preview answers the question instantly.
- Inspecting images in test fixtures. Snapshot tests and fixtures often store expected images as Base64 strings in JSON. Decoding one shows what the test actually expects, which helps when a visual regression check starts failing.
- Pulling icons out of config files. App manifests and browser extension configs sometimes carry icons as encoded strings. Decode the string to extract the original PNG when the source asset has been lost.
- Verifying clipboard or websocket payloads. A canvas export or websocket message hands you PNG data as text. Decoding it locally in the browser confirms the capture worked, without sending the bytes to any server.

About the Base64 Decode PNG tool
Base64 Decode PNG is a free online tool that works entirely inside your web browser. Decode a Base64 string back into a downloadable PNG file. Because the processing happens on your own device, nothing you enter is uploaded, logged or stored anywhere.
This page is one of 200 Image utilities on EditSafely. Each one does a single job well, and all of them follow the same rule: your input stays on your machine.
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.
Because nothing leaves your device, the tool is suitable for sensitive content such as internal documents, credentials or customer data. It also responds instantly, since every keystroke is handled on your own machine rather than by a remote API.
Frequently asked questions
Is Base64 Decode PNG free to use?
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?
Everything happens locally. Your browser downloads the tool's code once, then does all the processing itself; nothing you enter is transmitted, stored or logged. You can even go offline after the page loads and it will still work.
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?
No. The tool works in any modern browser on desktop, tablet or phone. There is no account to create, no extension to add and no software to install.
How do I save the output?
Click the Download button once the result is ready. The file is built in your browser's memory and handed straight to your downloads folder, without passing through a server.
