Can this tool decode any Base64 string into readable text?

The tool forces the decoded result to be displayed as an ASCII string, which may discard invalid characters and produce incorrect results if the original data contains non-ASCII characters or binary content not meant for text conversion.

Is it better to use this tool instead of a standard Base64 decoder?

For most scenarios, a standard Base64 decode tool is exactly what you need. Use this tool only if you specifically need to change the charset encoding to ASCII, as regular decoding will preserve the original data format more accurately.

What should I do if the decoded result contains garbled characters?

If the output appears as garbled characters or symbols, the Base64 string may have been encoded from binary data or non-UTF-8 text. The tool recommends using standard Base64 decoding rather than forcing ASCII conversion in such cases.

Can I upload a file to decode instead of pasting text?

Yes, the tool supports uploading files for Base64 decoding, allowing users to process encoded files directly through the online interface without manual copy-pasting.
