Frequently Asked Questions
What is an Image to Base64 Converter?
An Image to Base64 converter translates binary image files (PNG, JPG, WebP, SVG) into text strings formatted as Data URIs. This allows embedding images directly into HTML or CSS without separate HTTP requests.
Can I convert Base64 back into an image file?
Yes! Switch to the 'Base64 to Image Decoder' tab, paste your Base64 string or Data URI, and click Download to save the reconstructed PNG/JPG file.
Does converting to Base64 increase file size?
Yes, Base64 encoding increases the raw text payload by approximately 33% compared to the original binary file, which is why it is best suited for icons, small graphics, and email templates.
Is my data stored or sent to any server?
No. The entire encoding and decoding process is executed 100% inside your browser via the HTML5 FileReader API.
