QR Code Kaise Banaye: Free QR Aur Barcode Generator Ki Guide

Dukaan ke counter par, poster par, wedding card par, ya kisi form ke neeche - QR code aaj har jagah dikhta hai. Achhi baat ye hai ki apna QR code banana ke liye kisi designer ya paid app ki zaroorat nahi hai. PDF Saathi Hub ka QR & Barcode Generator ek free tool hai jo aapke browser me hi QR code ya standard barcode banata hai aur PNG ya SVG image ke roop me download deta hai. Aap jo type karte ho wo kisi server par nahi bheja jaata.

Is guide me hum dekhenge: QR aur barcode me kya chunna chahiye, step-by-step code kaise banayein, aur print ya share karne se pehle kaunsi jaanch sabse zaroori hai.

Tool kya karta hai?

Generator ke do mode hain:

• QR Code mode - koi bhi text, multi-line content, Hindi text, website link, email ya address. QR me jo likhoge wahi save hoga.

• Barcode mode - chhote English/numeric codes ke liye. Formats: CODE128 (English, digits aur common symbols), EAN-13 (12 ya 13 digits), UPC-A (11 ya 12 digits).

Size (General ya Big) aur color choose karke Create Code dabao, preview dekho, phir Download PNG ya Download SVG se image save karo. PNG normal use ke liye theek hai; SVG printing ke liye scalable format hai.

Step-by-step: QR code kaise banayein

1. Decide karo kya rakhna hai. Website link, plain text, email ya address - jo bhi QR me chahiye, pehle se ready rakho. Link hai to poora address bilkul sahi likho (https:// samet).

2. Tool kholo. PDF Saathi Hub par QR & Barcode Generator page open karo. Signup nahi chahiye.

3. Text type karo. Dhyan rahe - tool email ya address ki correctness automatically check nahi karta. Jo likhoge wahi encode hoga.

4. Size aur color chuno aur Create Code dabao.

5. Preview ko scan test karo. Doosre phone ke camera ya scanner se preview scan karo aur decoded text ko apne input se milao. Galat destination wala QR bhi dekhne me bilkul theek lagta hai - isliye scan test sabse important step hai.

6. Download karo. PNG ya SVG me save karo aur file ka naam samajhne layak rakho.

Print karne se pehle 4 checks

1. Scan test usi size par karo jis size me print hoga. Browser preview ka success printed output ki guarantee nahi hai.

2. White margin (quiet zone) mat kato. QR ke chaaron taraf ka khaali border scan ke liye zaroori hai.

3. Contrast high rakho. Bahut halka color ya low contrast par scan fail ho sakta hai.

4. Static QR ka link baad me nahi badalta. QR me jo data encode ho gaya wo permanent hai. Naye destination ke liye naya code banao. Website links ke liye download se pehle destination khud kholkar dekh lo.

Barcode kab use karein?

Barcode sirf chhote English text aur numbers ke liye hai - long paragraphs ya Hindi ke liye nahi. EAN-13 aur UPC-A retail product numbers ke liye hote hain aur inme sahi digits/check digits zaroori hote hain. Dhyan rahe, ye tool official product number generate nahi karta - wo apni authority se milta hai. Agar barcode me leading zeros ya special characters zaroori hain, to download ke baad scan result se match zaroor karo.

Privacy aur safe use

Koi bhi vyakti QR scan karke uski information padh sakta hai. Isliye personal ID, secret password ya private document ka unrestricted link kabhi QR me mat daalo. Aur ek baat - QR banana us destination ko safe declare nahi karta. Jo link aap encode kar rahe ho, wo aapki apni zimmedari hai.

Common sawaal

Kya QR ka destination baad me change kar sakte hain?
Nahi. Static QR me encode hua data change nahi hota. Nayi value ke liye naya code banao.

Kya tool free hai? Files upload hoti hain?
Haan, bilkul free hai - no watermark, no sign-up. Sab kuch aapke browser me locally process hota hai; aapka input kisi server par upload nahi hota.

Kya QR me Hindi text chalega?
Haan, QR mode me Hindi, multi-line text, email aur address sab chal jaate hain. Barcode mode sirf English/numeric ke liye hai.

SVG ya PNG me kya chunoon?
Normal sharing aur documents ke liye PNG kaafi hai. Agar code bade size me print hona hai (poster, banner), to SVG better hai kyunki wo bina quality khoye scale hota hai.

Agla step

QR image download karne ke baad agar use kisi document ya PDF me jodna ho, to PDF Saathi Hub ke JPG to PDF ya PDF Merge tool se kaam poora karo. Dono free hain aur browser me hi chalte hain.
