FAQ
Does it support binary files?
This tool focuses on text. Large binary files are better handled with dedicated utilities.
Is Base64 encryption?
No. Base64 is encoding, not encryption—anyone can decode it.
Why did decode fail?
Invalid characters, padding issues, or non-Base64 input cause errors. Trim whitespace and retry.
Should I paste secrets here?
Avoid pasting production secrets on shared machines. Prefer local dev environments.
