Hamar PDF merge tool 100% browser-based hai — aapki files kisi server par upload nahi hoti:

Technical Process:

• Jab aap PDF files select karte hain, woh aapke browser memory mein load hoti hain
• PDF-lib library (open-source JavaScript) use hokar saare PDFs ko ek saath process karta hai
• Merged PDF bhi browser memory mein create hoti hai aur directly aapke device par download hoti hai
• Poore process mein koi bhi data internet par nahi jaata

Privacy Verification: Browser DevTools (F12) → Network tab open karein aur files upload karein — aap dekhenge ki koi network request nahi jaati. Sab kuch purely client-side hai.

Sensitive documents ke liye perfect: Bank statements, Aadhaar/PAN documents, medical reports, legal contracts — koi bhi sensitive PDF safely merge kar sakte hain bina server par bheje.

Technically hamar tool par koi strict file count limit nahi hai — aap jitni chahein utni PDF files merge kar sakte hain. Practical considerations:

Recommended: 2–20 files ek saath merge karna best experience deta hai — fast processing aur manageable file size.

File Size Limits:

• Individual file: Max 50MB per PDF recommended
• Total combined size: Aapke device ki available RAM par depend karta hai
• Modern devices (4GB+ RAM) mein 100MB+ total size bhi smoothly handle ho jaata hai

Performance Tips:

• Bahut large PDFs ke liye pehle PDF compress karo, phir merge karo
• Chrome ya Firefox browser best performance deta hai PDF processing ke liye
• Agar browser slow lag raha hai toh PDF files ko batches mein merge karo

Hamare tool mein “Add More” button se kisi bhi waqt additional files add kar sakte hain existing list mein.

Hamar tool mein PDF files ka order change karne ke 2 aasaan tarike hain:

Method 1 — Drag & Drop:

• File card ke baaye side par ⠿ drag handle icon dikhega
• Is icon ko pakad kar (click & hold) file card ko upar ya neeche drag karein
• Sahi position par chhod dein — file wahan aa jaayegi
• Mobile par bhi drag & drop kaam karta hai touch ke saath

Method 2 — Arrow Buttons:

• Har file card ke right side par ↑ ↓ arrow buttons hain
• ↑ button se file ek position upar jaati hai
• ↓ button se file ek position neeche jaati hai
• Yeh method precise ordering ke liye best hai

Order verify karna: File list mein har card ke left side par number (1, 2, 3…) dikhta hai jo final merge order batata hai. Merge button click karne se pehle order confirm kar lein.

Files merged PDF mein exactly usi order mein aayengi jis order mein list mein hain — pehle file ke pages pehle, phir doosri file ke pages.

Agar merged PDF download nahi ho raha toh yeh steps try karein:

Step 1 — Browser Popup Blocker check karein:
Bahut se browsers automatically download block kar dete hain. Address bar mein dekho — ek popup blocked notification hogi. Us par click karke download allow karein.

Step 2 — Different Browser try karein:
Chrome ya Firefox mein best compatibility hai. Edge, Safari bhi mostly kaam karta hai. Agar ek browser mein problem hai toh doosra try karein.

Step 3 — Corrupt PDF check karein:
Kabhi kabhi ek corrupt ya password-protected PDF merge process fail kara deta hai. Ek-ek karke files remove karke identify karein kaunsi file problem create kar rahi hai.

Step 4 — Memory issue:
Bahut large PDFs browser ka memory use khar dete hain. Browser tabs band karein, page refresh karein aur phir try karein.

Step 5 — JavaScript check karein:
Browser mein JavaScript enabled hona chahiye. Settings → Site Settings → JavaScript → Allow karein.

Password protected PDFs ke baare mein kuch important information:

Short answer: Hamar current tool password protected PDFs merge nahi kar sakta। Agar aap password-protected PDF add karte hain toh merge process fail ho sakta hai ya error aa sakta hai.

Solution — PDF password pehle remove karein:

• Adobe Acrobat Reader (Free): PDF open karein → File → Print → “Save as PDF” printer select karein → Save. Password generally remove ho jaata hai.
• Chrome browser: Password-protected PDF Chrome mein open karein (password enter karein) → Ctrl+P → “Save as PDF” → Save karein — new PDF bina password ke save hogi
• Online tools: PDF password remove karne ke liye dedicated tools available hain — PDF unlock tool use karein pehle

Password remove karne ke baad PDF hamare merge tool mein perfectly kaam karegi।

Note: Sirf woh PDFs unlock karein jinke aap legitimate owner hain. Doosron ki protected files unlock karna unauthorized hai।
