Zlib Tool

Zlib Tool is a focused local utility for encoding and decoding Base64 zlib data directly from the Chrome toolbar. Features: - Encode UTF-8 text as standard Base64 zlib data. - Decode Base64 zlib data into text or lossless hexadecimal bytes. - Find zlib/Base64 payloads embedded in logs and JSON. - Display multiple decoded payloads in source order. - Recognize supported protobuf-style metadata envelopes. - Build envelopes from JSON, text, or hexadecimal payloads. - Move results between Encode and Decode without using the clipboard. - Optionally live-decode visible payloads in rendered text, fields, and CodeMirror-style editors across supported browser tabs. - Process everything locally with no network requests or stored payloads. Zlib Tool requests optional all-sites access only when you enable the footer live-decode toggle. Its packaged script then covers supported existing and future tabs. Rendered values and read-only fields can switch between decoded and original content. Editable fields and contenteditable code editors—including Temporal UI output boxes—stay unchanged and receive a separate decoded preview. Original values and decoded results remain in temporary memory. Turning the toggle off restores pages, removes previews, unregisters the decoder, and removes the optional site permission. What's new in 1.0.2: - Decode zlib/Base64 values in read-only fields and CodeMirror-style editors, including Temporal UI output boxes. - Keep editable fields and editors unchanged while showing decoded content in a separate preview. - Switch individual rendered values between decoded and original content. - Show a persistent live-decode state, current covered-tab count, and clearer site-access explanation. - Fit the complete single-result workflow within Chrome's popup viewport. - Improve control sizing, supporting-text readability, and copy confirmation. - Restore original values and remove previews when live decoding is disabled. - Keep all detection and decoding local with no network requests or stored payloads.
