Hi @abivanth.r

Use Read PDF with OCR activity. By Default the scaling will be 2. You can enter scale from 0 to 5. and you can change the Profile too. Usually for Scanned PDF’s keeping Profile as None and scaling 2 should work. This is not same at all cases. So start the scale from 0 and increase it by 0.5. Keep Profile as None or scan. Check in both the ways which the extracting the data accurately.

If Tesseract OCR Engine doesn’t work you can go with OmniPage OCR engine. For this you need to download the dependency UiPath.OmniPage.Activities. In this also you will have Profile and scan. keep that accordingly and check. larger values for Scaling in OmniPage OCR engine fails.

Hope you understand!!

Use Omnipage ocr it extract the Pdf Data correctly as compared to other OCR’s it can extract Chinese and English Data by slightly changing the Image DPI and Scales.

@abivanth.r

Try changing different Scalings until you get the data properly,But remember ocr activities does not extract the data 100% accurare you to keep the track that which scaling gives you the best data extraction you have to stick on that.
I hope it helps you
