Convert PNG to Base64
PNG is a strong choice for logos, icons, and UI assets because it supports lossless compression and transparency. This png base64 converter encodes your PNG file into text you can embed in code.
Upload a PNG file and copy the encoded output. You can use the result as png to base 64 data in HTML, CSS, JavaScript, JSON, or API payloads.
PNG Data URI Format
A PNG data URI usually starts with data:image/png;base64, followed by the encoded characters.
When you need a data image png base64 value, copy the full URI from the Data URI tab. Paste it into your project wherever a URL or string is expected.
You can also treat the output as image png base64 text when you store the encoded value without the prefix.
Convert Base64 Back to PNG
Paste encoded PNG text into our Base64 to Image page when you need to reverse the process. Preview the image and download the PNG file in one step.
This base64 to png workflow helps when you receive image data from an API, database field, or exported report.
Transparent PNG and File Size Notes
Base64 keeps alpha transparency for PNG files, so icons and overlays stay usable in CSS and HTML.
PNG Base64 strings are larger than the original binary file. Use them for small assets such as icons and badges, not large screenshots or photo galleries.
PNG Base64 Examples
HTML example: place a data:image/png;base64,... value inside an img tag src attribute.
CSS example: use background-image: url("data:image/png;base64,..."); for small icons or placeholders.
