Frequently Asked Questions

Because some users need to process very large batches (several hundreds) quickly, and the online portal is not designed for that throughput.
e-FFF, UBL (2.x) and XML (UBL 2.x included).
Are there other free tools available online? Yes, there are other tools on the internet that offer partial UBL viewing or conversion features. With UBLKIT Desktop, our focus was different: we deliberately designed the application to be simple, reliable, and comfortable to use in real-world scenarios. The application works fully offline, supports multiple languages, allows file associations so invoices open directly with a double-click, and renders invoices correctly whether or not a readable version is embedded in the UBL file. You don’t need additional software, plugins, or online services — everything is handled by the application itself. These choices are the result of significant attention to detail and product craftsmanship. They are what make UBLKIT Desktop a complete, professional tool rather than a basic viewer.
This tool saves you significant time over and over again. IT also helps to cover the costs of developing and maintaining the tools. Your license is valid for 1 year.

What people say about UBLKIT Desktop

★★★★★

Au début j’étais hésitant, mais UBLKIT Portable m’a convaincu. traitement par lots de gros volumes et aussi licence pour un seul PC changent vraiment la donne.

UBLKIT Portable surprised me. I was sceptical at first, but single-PC license and the fact it provides offline use made my daily work easier. Honestly, UBLKIT Portable is a relief — single-PC license, plus offline use. I don’t want to go back to how it was before.
