    UTF-8 Support

    Our converter correctly handles multi-byte characters (emojis, non-latin scripts) using TextEncoder APIs.

    Safe & Local

    Encoding and decoding occur purely on the client-side. No data is ever transmitted to our infrastructure.

    Binary Data

    For binary files (images, PDFs), please use our upcoming specialized Binary-to-Base64 uploader tool.
