Frequently Asked Questions
Is decoding done locally?
Some builds decode in-browser; others use server assist for huge strings—check the page note.
Is there a size limit?
Multi-megabyte Base64 may hit browser memory caps—split or decode via CLI for giants.
Can I decode password PDFs?
Decoding reveals the locked PDF; unlock separately if you know the password.
What if preview is blank?
Ensure the string is standard Base64, not URL-safe variant unless supported.
Does it validate malformed input?
Invalid padding shows an error—re-copy from source without line breaks broken.
Can I batch decode?
Paste one payload at a time in the standard UI; script batch jobs locally for hundreds.
