Free Chrome Extensions & Browser Tools (2026)

Zovo Chrome Extensions & Browser Tools

A focused collection of Chrome extensions and free browser-based tools, built and maintained by one developer, Michael Lip. Each tool solves one problem well.

All Zovo extensions use Manifest V3 and are free to install. The free browser tools run in your browser. License checks and optional conversions contact Zovo's server.

Chrome Extensions

Free Browser Tools

No install required. These run entirely in the browser tab:

• JSON Formatter — Paste, format, and validate JSON with syntax highlighting.
• Base64 Encoder and Decoder — Convert Base64 strings and files without uploading anything.
• Password Generator — Generate strong passwords with configurable length and character sets.
• Color Palette Generator — Build a palette from any starting colour.
• Word Counter — Word, character, and sentence counts with a reading-time estimate.

Some of the same jobs can be given to an AI assistant instead of a browser tab. Zovo also publishes MCP servers that let Claude or Cursor work on a file where it already sits, so you can ask a spreadsheet on your own disk what is in it rather than pasting its contents into a chat.

When an Extension Stops Working

Extensions break for a short list of reasons, and the error message usually tells you which one. Our guide to Chrome extensions not working maps each message to its fix, including the corrupted-extension warning and the case where an extension survives in one profile but not another. If the same update also took your bookmarks, that is a different problem with a different recovery path, covered in Chrome bookmarks disappeared.
