Frequently asked questions
What is a UBL invoice?
A UBL invoice is an invoice in XML format, used for e-invoicing between businesses and the Dutch government (Peppol). It looks like code, but contains the same data as a PDF invoice. Our viewer makes it readable like a normal invoice, without having to send it to your accountant.
How do I know if an IBAN is actually valid?
An IBAN has a built-in checksum: the two digits after the country code are computed from the rest. Our tool validates that formula (MOD-97) and also identifies the bank from the code. A valid IBAN doesn't guarantee the account exists, but it does guarantee no typos.
What is base64, and when do I need it?
Base64 is a way to represent binary data (like an image) as plain text. You encounter it in data: URLs, email attachments and API tokens. Our encoder works both ways, text to base64 and back, without the content touching our servers.
