Convert any image to a Base64-encoded string in your browser — nothing is uploaded to any server and no account is required. Paste the result directly into HTML, CSS, or JSON.
Front-end developers embed small icons and logos as Base64 to eliminate extra HTTP requests. Email template designers inline images because many email clients block external image URLs. Mobile app developers encode images for JSON API payloads.
