OmniUtils 作成者: chandreshjulian

OmniUtils puts the tools you reach for most right in your browser toolbar — no tab switching, no external sites, no setup.

JSON Formatter
Paste any JSON and get instant syntax-highlighted output with collapsible nodes and line numbers. Automatically unwraps double-stringified payloads, so API responses and log entries that have been serialized multiple times display correctly without any extra steps.

Clipboard Manager
Captures everything you copy across the web and keeps a running history in the popup. Never lose a snippet you copied five minutes ago. Supports both local and session storage — session history clears automatically when you close the browser.

Codec
Encode and decode Base64 strings in one click. For JWT tokens, decode the header and payload instantly without a secret — or paste your secret to verify the signature and see a clear valid/invalid indicator.

Timezone
A multi-timezone clock with a reference-time converter. Set a home timezone, add additional zones, and enter any time to see it converted across all your zones simultaneously.

Settings
Four popup size presets (Compact, Default, Comfortable, Wide) let you size the panel to your workflow. Your preference is remembered across sessions.
