Overview

Product summary

Review the store description, core capabilities, and common use cases.

This is a tiny extension that does just one thing: Decodes Base64 strings.

To use, simply highlight the string you wish to decode, right-click it, and select 'Base64 Decode'.

Note: depending on the structure of the page, decoding the string may cause some funny formatting issues. Refresh the page to restore structure/formatting.

This plugin runs 100% locally in your browser, no data is collected or transmitted in any way.

It works, but on a dark themed website, it replaces the text background with a light background and leaves the text color as also light, in order to see anything inside the bright white strip, you need to select the text again (I find that triple clicking the line works best).

Works as advertised but on sites with dark backgrounds the white background highlight can not only be overly bright but also hard to read due to low contrast with font color. Would have been preferable to not highlight the converted string.

It would be awesome if this extension could identify and decode all discontinuous base64 strings on a page. Otherwise, it works as advertised in Chrome for macOS. Links don't have to be highlighted; simply right-click to decode. Thanks!

Does one thing and does it well. No 'buttons' to deal with. Love that it decodes inline and allows copy of results.
