Escape Lab
The right notation for the right context.
Escape and unescape JSON, JavaScript strings, HTML/XML entities, CSS strings, URLs and Unicode notation with explicit context boundaries.
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 Escape Lab
Paste input, select a command and its options, then run the transformation. Review diagnostics before copying or downloading the result. Input is not executed.
JavaScript output is a quoted string literal, not executable code. CSS uses hexadecimal string escapes, not identifier escaping. Generic escaping does not prevent injection in every context. Use parameterized database queries and context-aware output handling; SQL escaping is deliberately not offered.
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.
Does escaping make input safe?
Only for the precise destination grammar and usage. An HTML entity, URL component and JavaScript string follow different rules. Escaping is not a universal security boundary.
