Why Use Our Online Generators?

Online generators automate repetitive time-consuming tasks that would otherwise require specialized software or technical skills. Our collection of free 2026 generators covers all essential needs of professionals and individuals.

Advanced QR Code Generator

Our QR code generator creates smartphone-scannable 2D barcodes with many options: URL/web link, plain text, email (mailto:), phone number (tel:), SMS, WiFi (SSID + password), vCard contact, geolocation. Complete customization: size from 128px to 2048px, QR code color (black default, customizable), background color, central logo addition (up to 30% surface without affecting scannability), error correction level (L 7%, M 15%, Q 25%, H 30%). High-resolution PNG/SVG export for professional printing. Common uses: contactless restaurant menu, event poster, digital business card, guest WiFi sharing, mobile payment.

Professional Invoice Generator

Our invoice generator creates invoices compliant with French legal obligations (2018 anti-fraud law, mandatory mentions) in a few clicks: custom header (logo, contact info, SIRET), automatic sequential numbering, customer data (name, address, intra-community VAT number), product/service lines (description, quantity, unit price excl. VAT), automatic VAT calculation (20%, 10%, 5.5%, 2.1% or basic exemption), total incl. VAT, payment terms, bank details. Professional PDF export ready to send. Compliant for self-employed, micro-businesses, SMEs. Considerable time savings vs paid invoicing software ($50-150/month).

Secure Password Generator

Our password generator creates ultra-secure cryptographically strong passwords: adjustable length (8-64 characters, 16+ recommended for maximum security), character options (uppercase A-Z, lowercase a-z, digits 0-9, symbols !@#$%^&*), ambiguous character exclusion (0/O, 1/l/I), batch generation (up to 100 passwords simultaneously), password strength estimation (weak/medium/strong/very strong), estimated brute force crack time. Uses browser Web Crypto API for cryptographic random generation (CSPRNG). Ideal for: online banking accounts, professional emails, VPN, password managers. IMPORTANT: use a password manager (Bitwarden, 1Password, KeePass) to store these complex passwords.

Lorem Ipsum Text Generator

Our lorem ipsum generator creates filler text (dummy text, placeholder text) for web mockups and prototypes: words (5-500), sentences (1-50), paragraphs (1-20), choice between classic Lorem Ipsum (Latin) or modern French, HTML option (

tags), one-click copy. Essential for web designers, graphic artists, front-end developers creating wireframes, Figma mockups, WordPress templates, newsletters without final content. Lorem Ipsum avoids real content distraction and allows focus on visual design and layout.

Security and Compliance

Our secure generators respect your privacy: 100% local processing for password, QR code and lorem ipsum generators (no data transmitted), for invoice generator: local JSON save option or direct PDF export without server storage. Legal compliance: invoices with all mandatory French mentions (article 289 CGI), QR codes tested for universal compatibility (ISO/IEC 18004). Our tools do not replace an accountant for complex situations (international invoices, intra-community VAT, special exemptions).

Frequently Asked Questions

Yes, static QR codes generated by our tool are permanent and work indefinitely. Unlike dynamic QR codes (paid services like Bitly, QR.io) that redirect to a modifiable intermediate URL, our QR codes directly encode the final information (URL, text, WiFi...). Once generated and printed/shared, the QR code will always work, even if our site no longer exists. Static QR code disadvantage: impossible to modify destination after creation (if you change URL, must generate new QR code). Major advantage: free, no tracking, no scan limit, no expiration.

Yes, our invoice generator includes all mandatory mentions required by French legislation (article 289 of the General Tax Code): unique sequential invoice number, issue date, complete seller identity (name/company name, address, SIRET/SIREN), customer identity, detailed product/service description, unit price excl. VAT, total amount excl. VAT, VAT rate and amount per applicable rate, total amount incl. VAT, payment terms and due date, late payment penalties. For self-employed under basic VAT exemption, mention 'VAT not applicable, article 293 B CGI'. WARNING: for complex situations (international export, reverse charge VAT, corrective invoices), consult an accountant.

Yes, our generator uses the Web Crypto API native to the browser (window.crypto.getRandomValues) which provides cryptographically strong random numbers (CSPRNG - Cryptographically Secure Pseudo-Random Number Generator). This is the same technology used by professional password managers. A 16-character password with uppercase + lowercase + digits + symbols has about 10^30 possible combinations, meaning billions of years of brute force cracking even with supercomputers. CRITICAL: security also depends on storage: NEVER write generated passwords on paper or unencrypted text file. Use an encrypted password manager (free Bitwarden, 1Password, KeePass) that stores your passwords in an AES-256 vault.

Yes, most of our generators offer many customization options. Invoice generator: company logo (image upload), custom colors, fonts, terms and conditions addition, specific legal mentions, currency choice (EUR, USD, GBP...). QR code generator: code color, background color, central logo addition, error correction level choice, custom dimensions. Password generator: exact length, included/excluded character types, batch generation. Default templates are professional and immediately usable, but you can adapt them to your brand guidelines.

Yes, several options depending on the generator. Invoices: PDF export (definitive archive), JSON export (raw data re-importable for later modification), local browser save (HTML5 localStorage, keeps your templates and last invoices). QR codes: high-resolution PNG download (300-600 DPI for printing), vector SVG export (infinitely resizable without quality loss), clipboard copy. Passwords: individual copy or complete list export (CSV, TXT). WARNING: for invoices, also keep a copy in your official accounting software if you use one (legal obligation to keep 10 years in France).
