Three steps, no uploads
Choose a tool, paste or open your data, then copy or download the result. File contents and verification keys are kept only in this page's memory.
Views show bounded previews for large documents; downloads contain the full processed output. Some conversions infer structure from samples and cannot preserve every format-specific feature.
Supported features and limits
Decoded claims are untrusted until verified. Never infer trust from the token alone. Keys are not stored.
