FlexinaTools

FlexinaTools is a collection of 46 free online tools that run entirely in the visitor browser: merge, split and compress PDFs, validate Peppol BIS 3.0 e-invoices against the real schema, convert gross/net VAT for 7 EU countries, decode and verify JWTs, resize and convert images, format JSON and XML, generate invoices and more. There is no account, no file upload and no usage limit - everything happens client-side, so user files never leave the device. The interface is available in 6 languages. Built by Flexina, a small digital studio in Liege, Belgium.
