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.
获得最佳结果的提示
请使用文件的副本进行操作，并在检查结果之前保留原件。在提交到门户网站、雇主或机构之前，请打开输出并查看每一页。如果有大小限制，请确认接收网站如何计算：有些把一千字节算作 1000 字节，有些算作 1024 字节。所有处理都在您设备上的浏览器标签页中进行，因此大文件取决于设备内存，在手机上可能需要更长时间。

常见问题
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.
