Frequently Asked Questions

What is Base64 encoding?

Base64 is a method of encoding binary data into ASCII text. It's commonly used to embed images in HTML/CSS, send binary data in JSON, and more. Base64 Decoder Pro makes this process simple and fast.

Is my data secure?

Absolutely! All processing happens in your browser. No data is ever sent to our servers. We don't track, store, or share your data. Your privacy is our priority.

What file types are supported?

We support images (PNG, JPG, GIF, SVG, WEBP), PDFs, audio (MP3, WAV, AAC, FLAC, OGG), video (MP4, MOV, AVI, WEBM), and text files (TXT, JSON, XML, CSV, HTML, CSS, JS).

How do I save a file?

Click "Save to Sidebar" button or press Cmd+S (Mac) / Ctrl+S (Windows) to save the active content. The file will appear in your sidebar for easy access.

What are keyboard shortcuts?

Cmd+S = Save, Cmd+D = Download, Cmd+C = Copy, Cmd+F = Search, Cmd+H = Replace, Cmd+Z = Undo, Cmd+Y = Redo. Boost your productivity with shortcuts!

How do I use Auto mode?

Toggle the "Auto" button in the toolbar. It will automatically detect your input type (Base64, JSON, URL, Hex, Binary, or Plain Text) and convert it accordingly.

Can I download converted files?

Yes! Use the "Download" button or press Cmd+D to download the current content as a .txt file. You can also save files to your sidebar for later use.

Does it work offline?

Yes! Base64 Decoder Pro is a PWA (Progressive Web App). Once loaded, it works offline and can be installed as a desktop app on your device.
