Frequently Asked Questions
What is Base64 image encoding?
Base64 converts binary image data into a string of ASCII characters that can be embedded directly in HTML, CSS, JSON, or any text format without a separate file.
Why use Base64 for images?
Base64 embeds images directly in code, eliminating an HTTP request. Useful for small icons, email templates, and offline apps where external image requests are not possible.
How much larger is the Base64 output?
Base64 encoding increases file size by approximately 33%. For images under ~5 KB this overhead is usually acceptable; for larger images, a CDN or separate file is more efficient.
Are my files uploaded to a server?
No. The entire conversion runs in your browser using the FileReader API. Your image never leaves your device.
Which output formats are supported?
Data URL (src-ready string), Raw Base64, CSS background-image value, HTML <img> tag, Markdown image syntax, and JSON string value.
