Frequently Asked Questions

Is Base64 decoding with PDFPilot really free?

Yes. Base64 Decode is completely free to use, with no sign-up or account required.

Are my files uploaded to a server?

No. The decoding runs entirely in your browser. Your file is never uploaded to PDFPilot's servers.

Why does the output download as decoded.bin instead of the original filename?

Base64 text only encodes a file's raw bytes — it doesn't carry the original filename or file type. Rename the downloaded file with the correct extension once you know what it should be.

What happens if the text isn't valid Base64?

You'll get a clear error message rather than a corrupted or empty file.

Can I decode a data: URI directly?

Not the whole URI — strip the "data:...;base64," prefix first and upload just the Base64 portion after the comma.
