FlexinaTools

The reflex of pros and small projects

FlexinaTools brings together 46 free online utilities across four universes—invoicing, PDFs, home projects, and developer shortcuts—all running 100% in your browser. Nothing you type ever leaves your device: no uploads, no accounts, no server-side processing. Built by Flexina, a management platform serving self-employed professionals and small businesses in Belgium and France, every tool reuses the same rules, algorithms, and checks the team applies daily for paying clients.

For business: decide with confidence

From e-invoicing to payment validation, FlexinaTools covers the everyday obligations of running a business. Validate Peppol BIS 3.0 and Factur-X invoices, generate PDF invoices with embedded SEPA QR codes, check IBANs and EU VAT numbers, calculate commercial margins, estimate loan schedules, compute Belgian rent indexation, and turn gross salaries into net for Belgium and France. Every calculator respects local regulations and tax rates, giving you answers you can trust.

Documents: convert without friction

Handle PDFs and images with zero software installs. Merge, split, compress, or extract pages from PDFs; convert PDFs to Word or images (PNG/JPEG); turn Word documents back into PDFs. Resize, compress, or convert images between WebP, JPEG, and PNG; strip EXIF metadata; generate complete favicon sets. All transformations happen locally, so your contracts, payslips, and invoices never touch a server.

Home & projects: measure before you act

Plan renovations and everyday tasks with practical calculators for electricity consumption, paint quantities, tiling, rooftop insulation thermal resistance, and unit conversions. Each tool surfaces the numbers you need before you buy materials or hire a contractor.

Tech: work smarter

Developers gain instant shortcuts for JSON and XML formatting and validation, Base64 and JWT decoding, UUID generation, SHA-256/SHA-512 hashing, regex testing, cron expression parsing, and text comparison. Password generators, QR-code builders, and word counters round out the toolkit, all executed client-side for speed and privacy.

Updated regularly, open to everyone

New tools and improvements land as field needs evolve—the latest version is always online, free, and ready to use. Whether you're a freelancer checking an invoice, a team preparing documents, or a developer validating JSON, FlexinaTools delivers the useful, made simple.
