Why does decoding fail?

Invalid characters, missing padding, or wrong MIME often cause failures — paste the exact string your upstream system emitted.

Can I decode without data: prefix?

Yes if you supply MIME manually or the tool guesses from magic bytes after decode.

Is output identical to the original?

Bytes round-trip exactly when Base64 matches the source file; recompression only happens if you export to a different codec.

How do I spot malware?

Decoded binaries should come from trusted providers — scan if the source chain is unclear.

Does clipboard paste truncate?

Some chat apps clip long strings — save to a .txt file before loading if previews shorten text.

Can WASM or workers decode faster?

Large payloads may freeze the tab momentarily — close heavy DevTools timelines while decoding.

Treat pasted strings like credentials; clear the field after download on shared machines.

Why is file huge on disk?

Base64 expands storage — the decoded file returns to normal binary size.
