Encode
Text becomes a transportable signal.
Encode text as Base64, bytes, entities or language-specific escapes. Inspect the representation without sending your text to a server.
Text-only workspace. Never executes input. General limit: 200,000 UTF-16 units per editor; some operations have tighter limits.
Private session · history disabled
Opt in to store up to five recent text transformations on this device. Never stored on an account or synchronized. Files are never included. Disable history stops new saves; Clear history deletes saved items.
How to use Encode
Paste input, select a command and its options, then run the transformation. Review diagnostics before copying or downloading the result. Input is not executed.
Byte encodings use UTF-8. UTF-16 output lists hexadecimal code units; UTF-32 lists hexadecimal Unicode scalar values. These are not byte-order-dependent file serializations. Malformed surrogate sequences are rejected rather than silently replaced.
Privacy and boundaries
Editor contents stay in your browser. Transformations run in a disposable worker and are never sent to a formatting or AI service. History starts disabled; enabling it writes text to local browser storage only. Clearing that history removes this tool’s saved entries, not data saved by other applications. The surrounding website may load its normal navigation and analytics, but the utility workspace is excluded from content-interaction capture.
Use the labeled operation selector for the available capabilities. Keyboard users can reach every control with Tab; Ctrl or Command plus K opens the command palette. Copy requires clipboard permission. Download creates a local text file. Clear removes the current workspace; it does not automatically delete an opted-in history. Inputs and outputs are always rendered as text, never as a runnable preview.
What is Base64 encoding?
Base64 represents three bytes with four ASCII symbols, adding padding when necessary. It is a transport encoding, not encryption.
