About this tool
Convert UTF-8 text to 8-bit groups and binary back to text. Spaces are ignored on decode; length must be a multiple of 8 and only 0/1 are allowed.
How to use: paste text, pick Text → Binary, copy. Reverse for a bit dump from a homework sheet or a protocol note. Invalid groups show an error instead of mojibake.
Example: Hi becomes 01001000 01101001. This is encoding, not encryption. Related: hex converter for a shorter dump, number base for integer bit masks.
Conversion stays on-device. After load, encoding works offline.
FAQ
Related Convert tools
JSON ↔ YAML
Convert JSON to YAML and YAML back to JSON in the browser. Paste a config, Kubernetes snippet, or API fixture and copy the other format. Parsing uses js-yaml locally. Documents are never posted to a converter.
JSON ↔ TOML
Convert JSON objects to TOML and TOML documents back to JSON in the browser. Handy for Cargo.toml, pyproject, and app config fragments. Parsing stays on-device.
JSON ↔ XML
Convert JSON objects to XML and XML documents back to JSON. Useful for SOAP leftovers, RSS, and mixed API stacks. XML is parsed with the browser DOMParser so payloads stay on the device.
JSON ↔ CSV
Turn an array of JSON objects into CSV, or parse CSV headers into JSON objects. Quote-aware parsing runs in the tab so spreadsheets of IDs and emails are not uploaded to a conversion service.
JSON to SQL
Turn a JSON object or array of objects into SQL INSERT statements. Set a table name, copy the query, and keep rows on the device instead of pasting fixtures into a hosted converter.
CSV ↔ TSV
Convert comma-separated values to tab-separated values and back, preserving quoted fields. A small delimiter swap for dumps you would rather not paste into a spreadsheet SaaS.
