PDF OCR
Scanned PDF ka text pehchaanein aur aisi file paayein jise search aur copy kiya ja sake.
Recognition aapke device par chalti hai, isliye scanned records aur archives aapke paas rehte hain. Pehli baar recognizer aur uska bhasha data ek public CDN se download hota hai; pages ka content kabhi nahi bheja jaata.
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. Har page 144 ya 216 dpi par image ki tarah dobara banta hai aur nayi file inhi images se banti hai, isliye wo original jaisi dikhti hai, lekin zyada resolution wala scan aapki chuni hui resolution par wapas aata hai aur links ya form fields saath nahi aate. Badle mein document ab 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.
Aksar pooche jaane wale sawaal
Kya pehchana gaya text scan ki jagah le leta hai?
Nahi. Har page ek image ki tarah rehta hai, 144 ya 216 dpi par dobara bana hua, aur pehchana gaya text uske peeche invisible roop mein juda jaata hai, isliye searchable PDF original jaisa dikhta hai. Kyunki file inhi images se dobara banti hai, zyada resolution wala scan aapki chuni hui resolution par wapas aata hai, aur links aur form fields saath nahi aate.
Recognition ke liye mere scanned pages upload hote hain?
Nahi. Recognition aapke browser mein chalti hai aur aapke pages kabhi bahar nahi jaate. Pehli baar browser ek public CDN se recognizer ki program files aur bhasha ka data download karta hai; aapke document ka kuch bhi nahi bheja jaata, aur bhasha ka data agli baar ke liye cache ho jaata 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.
