Frequently Asked Questions
What is base64 encoding for images?↓
Base64 encoding converts binary image data into a text string that can be embedded directly in HTML, CSS, or JavaScript as a data URL (data:image/png;base64,...). This eliminates an HTTP request for the image.
When should I use base64 images?↓
Use base64 for small icons, inline SVGs, or email templates where you cannot link to external files. For larger images, use standard URLs as base64 increases file size by ~33%.
What is the format of a base64 data URL?↓
A data URL follows the format: data:[mime-type];base64,[base64-string]. For example: data:image/png;base64,iVBORw0KGgo...
Can I decode any base64 string?↓
You can decode a base64 string with or without the data: prefix. If you paste just the raw base64 characters, the tool will automatically prepend data:image/png;base64, to preview it.
