What Is a Searchable PDF?
A regular scanned document saved as PDF is really just a picture of text — you can't select, copy, or search it. A searchable PDF has an invisible text layer placed precisely over the image, so the document looks the same but you can now select, copy, and search its text just like a normal document.
How Our Tool Creates Searchable PDFs
The Image to Searchable PDF (OCR) tool uses Tesseract OCR — an industry-standard text recognition engine — to detect every word in your scanned images, then embeds that text as a hidden, precisely-positioned layer over each page. The visual result is identical to your original scan; the difference is everything is now selectable and searchable.

Frequently Asked Questions
Will the searchable PDF look different from my original scan?
No — the original image is preserved exactly as-is; the recognised text is added as an invisible layer on top, so visually nothing changes.
Does it work with handwriting?
OCR engines like Tesseract are optimised for printed text — handwriting recognition is much less reliable and not the primary use case.
Is there a limit on how many pages I can convert?
Up to 20 images per conversion — run it again in batches for longer documents.
