Image to Base64 Converter
Upload an image to instantly get its Base64 data URL, or paste a Base64 string to preview it as an image.
Pourquoi utiliser cet outil ?
Embedding a small image directly in CSS or HTML (as a data URL) avoids an extra HTTP request. This tool converts an image to Base64 and back, directly in your browser.
Why it's free
A discreet ad banner covers hosting costs — that's the whole business model. No account to create, no usage limit, no paid tier unlocking the real result. Calculations run in your browser, so your numbers, dates and text never leave your device.
