Encoding
Local Base64 for Mac and iOS
Encode and decode Base64 text. Blissum keeps this utility local on macOS, iPhone, and iPad so you do not have to paste code, tokens, certificates, URLs, or private text into random online tools.
A private alternative to online base64 encoder tools
Encode text to Base64 or decode Base64 back to text, with auto-detection for Base64-looking input. Blissum can strip data URL prefixes and remove trailing null bytes when decoding, which helps with copied payloads and binary-adjacent text. It is a local Base64 encoder and decoder for tokens, examples, payloads, and debugging work on Mac, iPhone, and iPad.
Blissum groups everyday code, text, data, and web utilities into one local app for Mac, iPhone, and iPad, which is especially useful where iOS has fewer native developer-tool options.
