Frequently Asked Questions

Common questions about Base64 encoding.

Base64 encoding kya hota hai?

Base64 ek binary-to-text encoding hai jo binary data ko 64 printable ASCII characters (A-Z, a-z, 0-9, +, /) me convert karta hai. Ye emails, JSON APIs, data URLs me binary data bhejne ke liye use hota hai — jahan text-only channels hote hain.

Kya Base64 encryption hai?

Nahi! Base64 encryption nahi hai, ye sirf encoding hai. Koi bhi Base64 string ko easily decode kar sakta hai — koi key/password nahi chahiye. Sensitive data ke liye AES/RSA jaise actual encryption use karo. Base64 sirf format conversion hai, security nahi.

Base64 ka size kitna badhta hai?

Base64 encoded data original se lagbhag 33% bada hota hai. Ye 3 bytes ko 4 characters me convert karta hai. Example: 3 KB file ka Base64 ~4 KB hoga. Ye overhead size badhata hai par format compatibility deta hai.

URL-safe Base64 kya hai?

Standard Base64 me + aur / characters hote hain jo URLs me problems create karte hain (+ ko space samjha jaata hai, / path separator hai). URL-safe variant me + ko - se aur / ko _ se replace kiya jaata hai. JWT tokens aur URL parameters me ye use hota hai.

Hindi text ya emoji encode ho sakta hai?

Haan! Hamara tool UTF-8 encoding use karta hai, jisse Hindi, Tamil, Telugu, Bengali, Chinese, Japanese, Arabic, aur saare emojis (🌍 🎉 ❤️) properly encode aur decode hote hain. Purane tools jo sirf ASCII handle karte the, wo Unicode pe fail ho jaate hain — hamara nahi.

Image ko Base64 me kaise convert karein?

Toolbar me File tab pe jao → image drop/select karo → automatically Base64 me convert ho jaayegi. Copy Data URL button se poora data:image/png;base64,… format milega, jise HTML ke <img src="..."> me directly use kar sakte ho.

Kya ye tool free hai?

Yes, 100% free. No signup, no limit, no ads. Saara encoding/decoding aapke browser me hota hai — koi data server pe nahi jaata. Sensitive text bhi safe hai.
