Small things can hold a lot.
A note, an equation, a few lines of code. 2kb.site carries content inside the link in a QR code, so there is no saved document to fetch.
Made and read in your browser
Note content lives in the URL fragment — the part after the #. The browser does not include that fragment in its request to this site. Encoding, decoding, and unlocking run locally in a worker.
Anyone with a public note’s link can read it. Existing password and 256-bit secret sections can be unlocked independently. Authentication checks the document body; it does not identify its author.
More than words
Markdown supports tables, inline and display math, Mermaid diagrams, and highlighted code. Plain text stays literal, and original files and source bytes can be downloaded.
The name is a nod to small notes, not a promise of a fixed 2 KB capacity. Available space depends on compression, the link, and QR settings.
Create and share
Studio supports Markdown, plain text, and file attachments, with public, password, or 256-bit secret protection. Preview your note as you write, then share its link or export the QR as an image or printable PDF.
