Frequently Asked Questions
What is a PNG to Base64 converter?
A PNG to Base64 converter translates binary image data from a PNG file into a text-based ASCII string format. This allows you to embed images directly within HTML documents, CSS files, or JSON payloads as Data URIs without needing to host separate image files.
Is my image data uploaded to any servers?
Absolutely not. Image Studio operates entirely client-side. The conversion from PNG to Base64 happens directly inside your web browser’s memory. Your files are never sent to a backend server, making it 100% secure and private.
What does the "Line Splitting" feature do?
Line splitting breaks up the massive, continuous block of Base64 text into shorter, more readable lines. You can customize the exact character limit per line, which is extremely useful for maintaining clean, readable code in programming languages or configuration files that enforce line-length standards.
Can I use the output directly in my CSS or HTML?
Yes! By enabling the "Data URL" option, our tool wraps the raw Base64 code in the correct syntax (data:image/png;base64,...). You can paste this output directly into an HTML <img> tag's src attribute or a CSS background-image property.
