Convertitori
Converti qualsiasi unità — lunghezza, peso, temperatura, volume, area, velocità, energia, dimensione dei dati e altro ancora.
›Are these conversions accurate?
Yes. Every unit conversion uses double-precision floating-point math (15+ significant digits) with the official conversion factors.
›Do I need to install anything?
No — every converter runs entirely in your browser. There's no signup, no download, no upload.
›Can I share a specific conversion?
Yes. The URL updates with your input value and units, so you can bookmark or share any result directly.
Calcolatrici
Finanza, date e ora, salute e fitness, cucina e tipografia — calcolatrici per tutti i giorni.
›Are my financial or health data sent anywhere?
No. The calculators run locally; only the live exchange-rate endpoint is contacted, and only for public market data.
›Where do currency rates come from?
Live mid-market rates from the European Central Bank, refreshed multiple times per hour.
›Can I bookmark a specific calculation?
Yes — the inputs are encoded in the URL so you can share or save any scenario.
Formattatori e Codice
Formatta, minimizza e converti JSON, XML, YAML, CSV, SQL, regex — più generatori di codice, schemi, framework, DevOps e testing.
›Is my data sent to a server?
No. JSON, CSV, YAML, XML, regex and code-gen tools all run entirely in your browser — your data never leaves your device.
›How big a payload can I paste?
Anything your browser can hold in memory — typically several megabytes. Very large files are best processed locally with a script.
›Which languages can I generate types for?
TypeScript, C#, Java, Python, Go, Rust, Swift, Kotlin, Dart, Scala, Elixir, Haskell, C++ and PHP — from JSON or JSON Schema input.
Codificatori e Crittografia
Base64, URL, esadecimale, hash, HMAC, JWT, chiavi e cifrari classici — tutto lato client, mai registrato.
›Which hash and signature algorithms are supported?
SHA-1/256/384/512, HMAC, RSA, ECDSA, Ed25519 and PGP via the browser's Web Crypto API and OpenPGP.js. MD5 is intentionally omitted for security use.
›Can I decode a JWT or X.509 cert safely here?
Yes. JWT, X.509 and PGP tools all run locally — tokens, certs and keys are parsed in your browser and never sent over the network.
›Is Base64 Unicode-safe?
Yes — input is normalised to UTF-8 before encoding so accented characters, emoji and CJK round-trip correctly.
Generatore
UUID, password, codici QR, lorem ipsum, dati fittizi e selettori casuali — casualità crittografica integrata.
›Are passwords I generate ever logged?
Never. Passwords are produced by crypto.getRandomValues in your browser and are not transmitted anywhere. The password vault is encrypted client-side too.
›How random are the UUIDs and tokens?
All identifiers use the Web Crypto API's CSPRNG — the same source browsers use for TLS — so they're cryptographically suitable for tokens and keys.
›Can I generate codes in bulk?
Yes — UUIDs, passwords and QR codes all support batch generation with one click, downloadable as text or zip.
File e Media
Immagini, audio, video, PDF, ebook e utilità per file, tutto nel tuo browser.
›Are my files uploaded anywhere?
No. Image, audio, video, PDF and spreadsheet tools all process your files locally in your browser. Nothing is uploaded, stored or logged.
›What image formats can I convert between?
PNG, JPG, WebP, AVIF, HEIC, JFIF and SVG — plus resize, crop, rotate, compress, strip EXIF metadata and run a full image editor.
›How are audio and video processed?
All edits run client-side via FFmpeg-wasm or the browser's native Audio/Video APIs. Files stay on your device.
Colore e design
Colori, palette, contrasto, gradienti e unità CSS.
›Which color formats are supported?
HEX, RGB, HSL, OKLCH (perceptually uniform) and named CSS colors — convert between any of them in either direction, plus pick from images.
›Can I check WCAG accessibility contrast?
Yes. The contrast checker reports the ratio plus pass/fail for AA and AAA at both regular and large text sizes, and the color-blindness simulator previews common conditions.
›Do the CSS generators output Tailwind?
Where it applies, yes — the Tailwind colour finder maps any HEX/RGB to the closest Tailwind class.
