About this tool
A scanned PDF is really a set of pictures, so you cannot search or copy its text. OCR reads each page and places hidden text on top, and the pages look exactly as before. Pick the language: Bangla+English, English only, Hindi or Arabic.
When to use it
A scanned PDF is only pictures, so you cannot search or copy its text. OCR reads the pictures and adds an invisible text layer, so the PDF looks the same but becomes searchable and selectable. Bangla is supported.
Tips
Scan at 300 dpi, straight and in good light. Choose the right language. Proofread names and numbers, because OCR can confuse similar characters.
Privacy
Everything runs in your browser, so your data is not uploaded or stored.
獲得最佳結果的提示
請使用檔案的副本進行操作，並在檢查結果之前保留原件。在提交到入口網站、僱主或機構之前，請開啟輸出並檢視每一頁。如果有大小限制，請確認接收網站如何計算：有些把一千位元組算作 1000 位元組，有些算作 1024 位元組。所有處理都在您裝置上的瀏覽器標籤頁中進行，因此大檔案取決於裝置記憶體，在手機上可能需要更長時間。

常見問題
How accurate is Bangla recognition?
Clean printed text gives good results. Handwriting, blurry or tilted scans make more mistakes, so straighten and sharpen the scan first.
How many pages at a time?
Long scans can take a few minutes on a phone, so start with a few pages. Pages that already contain text are kept as they are.
Does it change how the PDF looks?
No. The pages look the same. A hidden text layer is added.
Does it read Bangla?
Yes, Bangla and English are supported for clear printed text.
