Image & PDF to Base64 Converter
You can utilize Base64-encoded string representations of images and PDFs to help facilitate the transference of binary data into text documents (e.g., HTML, CSS, JSON, XML). By encoding a file as a Base64 string you eliminate the issues associated with binary data damaging the structure of a text file. This method also allows you to attach an image or PDF to your text document by including a Data URI. In addition, the Base64 encoder is capable of accepting image files (JPG, PNG, GIF, WebP) and PDFs up to 50 MB in size. If you would like more information about decoding Base64 strings back into files, please refer to the section titled "Base64 Files".
