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 using a data URI — no separate file request needed.
What formats are supported?
JPG, JPEG, PNG, GIF, BMP, WebP, SVG, ICO, and TIFF images are supported for both encoding (image → Base64) and decoding (Base64 → image).
What is a data URI?
A data URI is a complete Base64 string with the MIME type prefix, like data:image/png;base64,... You can use it directly as an image src in HTML.
Is this tool free and private?
