Base64 एन्कोड और डिकोड.

Text up to 200,000 characters; binary file up to 5 MB. Base64 is not encryption.

Base64 represents bytes using printable characters and typically increases size by about one-third. Text mode uses UTF-8, while file mode preserves bytes. Invalid Base64 is rejected, and decoded binary output can be saved without opening it.
