Kya pehchana gaya text scan ki jagah le leta hai?

Nahi. Image bilkul waisi hi rehti hai aur text uske peeche invisible roop mein juda jaata hai. Isiliye searchable PDF original jaisa hi dikhta hai.

Recognition ke liye mere scanned pages upload hote hain?

Nahi. Recognition engine aapke browser mein chalta hai. Sirf bhasha ka data ek baar aata hai, aur browser use cache kar leta hai.

Ek baar mein kitne pages pehchan sakta hoon?

Har run mein tees tak, kyunki recognition itni dheemi hai ki lambe documents batch mein behtar sambhalte hain.

Kaunsi quality setting chunni chahiye?

Tez wali se shuru karein. Zyada wali tab lein jab likhaawat chhoti ho, scan purana ho, ya pehli koshish gadbad aayi ho.

Jis PDF mein pehle se text hai, us par OCR chala sakta hoon?

Chala sakte hain, par faayda nahi: pehle ek shabd select karke dekh lein. Text pehle se ho to seedhe convert karein.

PDF OCR ke baare mein

Scanned PDF document ki ek tasveer hai. Aap use padh sakte hain, lekin aur koi nahi: search kuch nahi paati, copy kuch nahi deti, aur har wo tool jo text par chalta hai khaali haath rehta hai. Text recognition isse theek karta hai — wo akshron ki shaklein padhta hai aur jo mile use file mein ek invisible layer ki tarah, chhape shabdon ke bilkul upar, likh deta hai. Page waisa ka waisa dikhta hai — scan ko chhua nahi jaata — lekin ab document searchable, selectable aur convertible hai. Recognition aapke browser mein chalti hai, baarah bhashaon mein se kisi bhi ek mein.

Common errors aur troubleshooting

Pehchana gaya text galtiyon se bhara hai. — Recognition scan par nirbhar hai. Zyada quality wali setting aazmayein aur dekhein ki bhasha page se milti hai — German page par English data theek yahi nateeja deta hai.
Recognition bahut dheemi hai. — Yeh sach mein bhaari kaam hai, aur wo server ke bajaay aapke apne processor par ho raha hai. Tez quality lein aur lambe documents baantein.
Do bhashaon wala document theek nahi pehchana ja raha. — Har run mein ek bhasha use hoti hai. Document ko bhasha ke hisaab se baantein, har hissa pehchaanein aur nateeje merge kar lein.
Haath ki likhaawat nahi pehchani gayi. — Yeh chhapa aur typewriter ka text pehchanta hai. Handwriting ke liye bilkul alag tarah ka model chahiye.
