Base64 & URL Encoder
Domande Frequenti
Tutto quello che devi sapere su Base64 e URL Encoding
Cos'e la codifica Base64?
Base64 e un sistema di codifica che converte dati binari in una stringa di testo ASCII usando 64 caratteri (A-Z, a-z, 0-9, +, /). Viene comunemente usata per trasmettere dati binari attraverso canali testuali come email (MIME), URL e JSON. La codifica aumenta la dimensione dei dati di circa il 33%.
Qual e la differenza tra Base64 e URL Encoding?
Base64 converte qualsiasi dato binario in testo ASCII ed e usata per incorporare file o dati binari nel testo. URL Encoding (percent-encoding) sostituisce i caratteri speciali negli URL con sequenze %XX per renderli sicuri nelle query string e nei parametri URL. Sono complementari: Base64 per dati binari, URL Encoding per caratteri speciali nelle URL.
La codifica Base64 e una forma di crittografia?
No, Base64 NON e crittografia. E una codifica reversibile che chiunque puo decodificare senza chiave. Non offre alcuna sicurezza. Se devi proteggere dati sensibili, usa algoritmi di crittografia come AES o RSA. Base64 serve solo per trasportare dati binari in formato testuale.
Questo strumento supporta i caratteri Unicode?
Si, lo strumento gestisce correttamente i caratteri Unicode (emoji, caratteri accentati, cinese, arabo, ecc.) grazie all'uso di TextEncoder/TextDecoder. I caratteri vengono prima convertiti in UTF-8 prima della codifica Base64, garantendo la corretta decodifica successiva.
What is the difference between Base64 and URL encoding?
Base64 turns binary data into ASCII text using 64 characters, while URL encoding replaces the special characters of an address with sequences such as %20, so they can be used safely in query strings.
Does Base64 encoding protect data?
Base64 encoding is not encryption: anyone can bring the string back to the original text with no key. Protecting confidential data takes a cipher such as AES or RSA.
Does Base64 handle accents and emoji?
Yes. The text is converted to UTF-8 before encoding, so accented letters, emoji and non-Latin alphabets come back identical when the Base64 string is decoded.
Does my data stay private?
Yes, and not because we promise it: this tool runs entirely inside your browser. What you type or upload never leaves your device, so it never reaches a server of ours and there is nothing we could keep, read or lose. You can check it yourself: open the page, disconnect from the internet, and the tool keeps working.
Do you store what I enter?
No. There is no database behind this tool: we do not store your files, your text or your results. When you close the tab nothing is left — not here with us, because it never arrived, and not anywhere else.
Do you profile me? Are you GDPR compliant?
We do not profile you: there is no account to create, we never ask for your email to use a tool, and we keep no profile of what you do. We are an Italian company and we work under the GDPR and the other European rules, with the privacy notice and the consent request in plain sight. One thing we say in full rather than hiding it behind a slogan: the ads on the page are Google's, and Google may use cookies to personalise them. You decide from the consent banner: if you say no the ads stay, but they are not personalised, and the tool works exactly the same.
If it is free, how do you make money?
From the ads on the page, and that is all. We do not sell your data, there is no hidden paid plan, there is no limit that eventually asks for your card, and you do not have to sign up. The ads pay for the servers and for the time we spend writing the tools: that is how we can keep them open to everyone.
