Features & Capabilities

Base64 Pal: Effortless Base64 Decoding Right in Your Browser

Base64 Pal is a sleek and user-friendly browser extension crafted to make decoding Base64-encoded text simple and convenient directly from your browser. Whether you stumble upon a line of mysterious, scrambled code buried in a webpage or need to decode multiple Base64 strings at once, Base64 Pal is your reliable companion for quick, on-the-fly decoding. The extension is perfect for developers, cybersecurity experts, researchers, and anyone curious about cryptic encoded content appearing online.

With Base64 Pal, decoding Base64 text becomes as easy as highlighting the string, right-clicking, and selecting your decoding option, no need to open new tabs, navigate to external websites, or fiddle with cumbersome tools. It integrates smoothly into your browser’s context menu, offering instant access without cluttering your interface. You can decode individual highlighted strings or scan the entire webpage to uncover every hidden Base64-encoded piece with just a single click. If you change your mind or want to revert any changes, the easy “Undo” feature restores the page exactly as it was before decoding.

Designed with user experience in mind, Base64 Pal offers smart content validation to ensure you decode only valid Base64 data and avoid errors. Decoded content can appear right where it matters or as transient tooltips to keep your workflow clean and distraction-free. Power users will appreciate the customizable keyboard shortcuts that accelerate decoding tasks, maintaining high efficiency while inspecting web content. Privacy-conscious users can rest easy knowing Base64 Pal operates entirely within the browser - it never sends, logs, or collects any personal or browsing data.

If you frequently encounter Base64-encoded data, want a fast way to decode it inline, or just need a lightweight, dependable decoding tool integrated into your everyday browsing, Base64 Pal is an essential addition to your browser toolkit.

Key Features:

  • Inline Decoding: Instantly transform highlighted Base64 text into readable content directly on any webpage.
  • Decode Entire Page: Scan and decode all Base64-encoded strings across the whole page with a single command.
  • One-Click Undo: Quickly reverse all decoding actions to restore the original content of the page without hassle.
  • Context Menu Integration: Seamlessly accessible through your browser’s right-click menu for intuitive use.
  • Keyboard Shortcuts: Customize hotkeys such as Alt+Shift+D to speed up decoding with minimal effort.
  • Visual Tooltips: Display decoded results as temporary tooltips, keeping your screen tidy and your work unobstructed.
  • Robust Input Validation: Ensures only valid Base64 strings are decoded, avoiding errors and unwanted operations.

How It Works:

  1. Install the Base64 Pal extension from your browser’s extension store.
  2. Browse any webpage and highlight any suspicious or encoded Base64 text.
  3. Right-click the selected text and choose “Decode Base64” from the context menu—or press the hotkey (default: Alt+Shift+D).
  4. The highlighted Base64 text is instantly replaced with its decoded equivalent. A tooltip appears momentarily to confirm the decoded output.
  5. To decode all Base64 content throughout a page, right-click the background and choose “Decode All Base64 on Page.”
  6. Need to revert? Simply right-click anywhere and select “Undo All Decoding” to restore the page to the state before decoding.
  7. Repeat decoding or undo actions as needed for a smooth browsing and inspection experience.

Privacy: - No personal data collected. Base64 Pal works entirely within your browser. It does not transmit, log, or collect any browsing or decoded information, ensuring your privacy and security are fully respected.

Is Base64 Pal Safe?

Risk impact
Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

Base64 Pal requires a few sensitive permissions. Exercise caution before installing.

Risk likelihood
Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Add-ons Store, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.
