Questions & Answers

As answered by people managing Android Studio and FlexinaTools.

How would you describe the primary audience of your product?

FlexinaTools's answer:

  • Small business owners, accountants and freelancers who deal with e-invoicing (Peppol, VAT, invoice generation) in the EU โ€” especially Belgium, France, the Netherlands, Germany, Spain and Portugal
  • Developers and technical users who need quick utilities: JWT decoding, Base64, JSON/XML formatting, hashing
  • Everyday users who want fast, private PDF and image tools without creating an account
  • Home-project planners who use the calculators (tiling, paint, insulation, mortgage)

What makes your product unique?

FlexinaTools's answer:

FlexinaTools is a privacy-first platform: all 46 tools run 100% in your browser, so your files and data are never uploaded to a server and no account is required. It goes beyond generic PDF utilities to cover niche professional needs โ€” Peppol BIS 3.0 e-invoice validation, VAT calculation for 7 EU countries, IBAN validation โ€” and the whole interface is localized in 6 languages (English, French, German, Spanish, Portuguese, Dutch).

Why should a person choose your product over its competitors?

FlexinaTools's answer:

Most online tool sites charge or rate-limit the same operations. With FlexinaTools, all 46 tools are completely free, with no sign-up, no paywall and no usage limits โ€” because everything runs in your own browser, we simply don't pay for server-side processing. On top of privacy (your invoices, PDFs and images never leave your device), it bundles things competitors don't have: a Peppol BIS 3.0.3 e-invoice validator, a multi-country VAT calculator and a full PDF + image + developer toolkit in one place.

What's the story behind your product?

FlexinaTools's answer:

FlexinaTools was built by Flexina SRL, a software company based in Liรจge, Belgium. It started as a collection of small utilities the team kept using internally โ€” invoice generation, VAT calculations, PDF merging โ€” and it grew when we noticed that people always ask for the same things: a quick tool, no account, and the guarantee that their files never leave their device. The guiding principle became: if the browser can do it, the server should never see it. Today the site groups 46 free tools around four universes โ€” business, documents, home projects and developer โ€” and is localized in 6 European languages.

Which are the primary technologies used for building your product?

FlexinaTools's answer:

  • Vue 3 single-page application with vue-router
  • Vite + vite-ssg: every page is statically generated at build time for fast loading and good SEO, in 6 locales
  • Client-side JavaScript libraries: pdf-lib and pdf.js for PDF operations, Aspose for advanced PDF processing, Canvas API for image tools
  • All computation runs in the visitor's browser โ€” the site itself is a static site with no application backend

Who are some of the biggest customers of your product?

FlexinaTools's answer:

  • FlexinaTools is a free, self-serve product, so it has no named corporate customers to list
  • Its daily users are individuals, freelancers and small businesses across the EU who validate Peppol e-invoices, merge PDFs or calculate VAT
  • The product is developed and operated by Flexina SRL, a software company based in Liรจge, Belgium
