How to use Convert PNG to Base64
- 1. Drop in your PNG. Add the image you want represented as text, such as a small icon or logo you plan to embed directly into code.
- 2. Let the tool encode the bytes. It reads the raw file bytes and encodes them into a Base64 string, a text-safe representation that can be embedded anywhere binary data is inconvenient.
- 3. Copy the Base64 string. Copy the resulting text and paste it into your source code, stylesheet, or configuration wherever you need the image embedded inline.
When to use Convert PNG to Base64
Convert PNG to Base64 encodes an image file as a Base64 string you can paste directly into code. It is the standard way to inline small images in CSS, HTML, or JSON without a separate file request.
- Inlining a small icon in CSS. You want a small icon embedded directly in a stylesheet as a background-image to avoid an extra HTTP request, and encoding it to Base64 makes that possible.
- Embedding an image in an API payload. An API needs to return an image directly inside a JSON response rather than a separate URL, and encoding the PNG to Base64 fits it into a text field.
- Storing an image in source control as text. A build script needs a small logo hardcoded as a constant in source code, and encoding it to Base64 lets you paste it in as a plain string.

About the Convert PNG to Base64 tool
Convert PNG to Base64 runs as plain JavaScript in your browser tab, with no server behind it. Encode a PNG file as a Base64 string you can paste into code. 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. 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.
