🔗
URL-Safe Mode
Standard + aur / ko - aur _ se replace karta hai — URLs mein safe use
📊
Live Stats
Input chars, output chars, ratio, size, valid Base64 check — sab real-time
↔️
Swap Mode
Input aur Output ek click mein swap — decode ke liye seedha
📁
File Upload (10MB)
Koi bhi file drag & drop karo — 10MB tak support
🖼️
Image Preview
Base64 se image preview — ya image upload karke Data URL pao
🕓
History

🔒
Offline Support
Internet band ho toh bhi kaam karta hai — sab browser mein hota hai
⚙️ Advanced Options — Kya Kaam Aata Hai?
🔗 URL-Safe Mode (- _)
Standard Base64 mein + aur / hote hain jo URLs mein break hote hain। URL-safe mode mein - aur _ use hote hain।
✅ JWT tokens, API keys, URL parameters ke liye use karo
📐 No Padding (=)
Standard Base64 mein = padding characters hote hain। Kuch systems mein yeh remove karna padta hai।
✅ Mobile apps aur kuch API integrations ke liye
📏 Wrap at 76 chars
Long Base64 string ko 76 characters ke baad line break karta hai — email standards ke liye zaroori hai।
✅ Email attachments aur MIME encoding ke liye
⚡ Live Convert
Type karte hi instantly convert hota hai — button dabane ki zaroorat nahi।
✅ Quick testing ke liye on rakho
🚀 Kaise Use Karein? (4 Simple Steps)
- Mode chuno — Text, File, Image ya URL — apni zaroorat ke hisaab se
- Input daalo — text type karo ya paste karo, ya file/image drag & drop karo
- Encode ya Decode — button dabao ya Live Convert on rakhne par automatic
- Output Copy karo ya Download karo — project mein use karo!
💡 Developer Tip: CSS mein small images embed karne ke liye
Image tab mein image upload karo → Base64 Data URL copy karo →
CSS mein background: url("data:image/png;base64,...")
use karo। HTTP request save hoti hai — page speed improve hoti hai!

❓ Aksar Pooche Jane Wale Sawaal (FAQ)
Q: Base64 kya hota hai?
Base64 ek encoding scheme hai jo binary data (jaise images, files) ko ASCII text characters mein convert karta hai। 64 safe characters use karta hai — A-Z, a-z, 0-9, +, /। Yeh encryption nahi hai — sirf encoding hai। Koi bhi easily decode kar sakta hai। Data transfer ke liye use hota hai jahan text-only format chahiye — jaise emails, URLs, APIs।
Q: Base64 aur encryption mein kya fark hai?
Base64 sirf encoding hai — koi security nahi deta। Koi bhi Base64 string easily decode kar sakta hai — koi password ki zaroorat nahi। Encryption (jaise AES, RSA) data ko secure karta hai — bina key ke decode nahi hota। Base64 ko kabhi security ke liye use mat karo — sirf data format conversion ke liye use hota hai।
Q: JWT token kaise decode karein?
JWT token teen parts hote hain — dots se alag: Header.Payload.Signature। Middle part (Payload) Base64Url encoded hota hai। Use copy karo → Text tab mein paste karo → Decode karo → JSON mein user info dikhega। Signature verify karne ke liye alag tools chahiye — yeh tool sirf payload decode karta hai।
Q: URL-safe mode kab use karein?
Jab Base64 output URL mein use karna ho — jaise query parameters, API endpoints, JWT tokens। Standard Base64 mein + aur / characters hote hain jo URL mein special meaning rakhte hain aur break ho jaate hain। URL-safe mode mein yeh - aur _ se replace hote hain — URLs mein safe hote hain।
Q: Image ko Base64 mein convert karne ka faayda kya hai?
Image Base64 mein convert karne se CSS ya HTML mein directly embed ho jaati hai — ek extra HTTP request save hoti hai। Small icons, logos ke liye useful hai — page load fast hota hai। Lekin bade images ke liye avoid karo — file size 33% zyada ho jaati hai aur page overall slow ho sakta hai।
Q: "Valid Base64" check kya karta hai?
Yeh feature check karta hai ki jo tumne paste kiya woh valid Base64 format mein hai ya nahi। Agar valid nahi hai — galat characters hain ya padding missing hai — toh error dikhayega। Debugging ke liye bahut useful hai — API response ya token decode karne se pehle validate kar sakte ho।
