Scanned PDF se text copy kaise kare
Scanned PDF me se text select ya copy kyun nahi hota? Kyunki scanned page asal me ek photo hai - text nahi. OCR (Optical Character Recognition) us photo ke characters ko pehchan kar asli text banata hai. Yeh guide batati hai ki PDF Saathi Hub ke OCR tool se kaise karein.
OCR aapke device par hi chalta hai - document kahin upload nahi hota. Pehli baar chalane par tool language data download karta hai (ek baar ka), isliye pehla run thoda lamba ho sakta hai.
Step by step: scanned PDF se text
- OCR PDF kholein aur scanned PDF select karein. File aapke device se upload nahi hoti.
- Language chunein - document jis bhasha me hai (Hindi, English, ya dono)। Sahi language chunna accuracy ke liye zaroori hai।
- OCR shuru karein। Pehli baar me language data download hota hai, isliye thoda samay lagega; baad ke runs fast hote hain।
- OCR ke baad naya PDF milta hai jisme text layer hai - ab aap text select, copy aur search kar sakte hain।
- Text ko kahin paste karein, ya PDF to Word se editable document banayein।
Best accuracy ke liye
- Saaf scan: 200+ DPI ka straight, shadow-free scan sabse acche results deta hai।
- Sahi language: Hindi document par English OCR chalane se galat characters aate hain।
- Printed text: printed/typed documents par accuracy bahut high hoti hai; handwriting par limited।
- Dark text, light background: low-contrast ya faded pages par errors zyada hote hain।
Honest limitations
Haath se likha text, bahut purane faded documents, ya heavily decorated fonts par OCR galtiyan kar sakta hai - output ko proofread zaroor karein, khaas kar numbers aur names। OCR ke baad bhi page ka visual layout same rehta hai; sirf text layer add hota hai।
