What is Image to Base64?
Pulze Image to Base64 encodes an image as a Base64 string — either a full data URI or the raw string — so you can embed it directly in HTML, CSS, or JSON without a separate file.
How to use Image to Base64
- Upload an image — Drop or select any image file.
- Choose Data URI or Raw Base64 — Data URI includes the MIME type prefix; raw is just the encoded string.
- Copy the result — Paste it directly into your code.
Frequently asked questions
What's the difference between Data URI and raw Base64?+
A Data URI includes a prefix like 'data:image/png;base64,' so it can be used directly in an <img> src or CSS background. Raw Base64 is just the encoded characters.
Does encoding increase file size?+
Yes — Base64 encoding increases size by roughly 33% compared to the original binary file.
Is my image uploaded anywhere?+
No, encoding happens entirely in your browser.
