Questions & Answers

As answered by people managing Smallpdf 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

Best Free Alternatives to Adobe Acrobat in 2026
Smallpdf is a well-known online PDF platform with a clean interface.

Best Online Image Converters in 2026: Docpose.cloud Leads the Pack
Users highlight Docpose.cloudโ€™s reliabilityโ€”no failed conversions even on rare formats. CloudConvert gets praise for quality tweaks but frustrates with daily resets. iLoveIMG is loved for extras like AI, but free limits irk. Smallpdf suits PDF-image hybrids, less pure images. Convertio is straightforward but caps freebies quick.
