How to Use:

Start by entering your Base45 string in the input box or uploading a text file using the “Choose File” button. The tool decodes input based on the RFC 9285 Base45 standard. If your string contains spaces or line breaks, you can toggle the “Ignore spaces and line breaks” option under the “Options” section. As soon as you enter valid input, the tool processes it and displays the decoded output in real time. Use the “Copy Output” button to copy the result or click “Export to File” to save it. When you’re ready to start over, hit “Clear All” to reset everything.

What the Convert Base45 to Text Tool can do:

This tool decodes Base45-encoded strings into UTF-8 text. It accepts input with or without padding, handles whitespace automatically, and processes both long and short payloads efficiently. In addition, it runs entirely in your browser. That means your data remains local, secure, and immediately viewable. You can also upload files in .txt, .log, .csv, .json, and other standard formats.

Convert Base45 to Text Example:

Input:

BB8GGF9WRT6D9C91F9WEH

Output:

Hello world!

Input with line breaks:

BB8GGF9WRT6  
D9C91F9WEH

Output (with “Ignore whitespace” enabled):

Hello world!

Common Use Cases:

Base45 decoding is useful in systems that rely on compact, alphanumeric representations such as QR code payloads, digital certificates, and transport tickets. Developers often use this format to handle data with limited character sets, while educators might demonstrate how encoding schemes function in practice. With live output, whitespace handling, and full file support, this tool provides a reliable solution for quickly converting Base45 strings back into readable text.

Useful Tools & Suggestions:

If you’re decoding Base45, there’s a good chance you’ll run into other formats too. Convert Base32 to Text keeps things tidy for shorter IDs, and Convert Base64 to Text is perfect when you’re juggling files or data blobs that came from APIs.
