This tool uploads your file — it's deleted automatically in 15 minutes
A scanned document is a stack of photographs, so searching it finds nothing and selecting text is impossible — the words are pixels, not characters. This tool reads the text with OCR and lays an invisible text layer behind each page, so the document looks identical but becomes searchable, selectable and copyable. It handles English and Hindi, which matters for Indian forms that mix both. Unlike every other tool here, this one runs on our server: OCR needs more processing than a browser can reasonably do, so your file is uploaded, processed and then deleted automatically within 15 minutes.
Your document still looks like your document
This is the part people worry about, and it is worth being clear: the page images are kept exactly as they were. The OCR text is added behind them, invisible, so the certificate, marksheet or contract still shows the original scan with its seals, signatures and layout intact. Nothing is redrawn or retyped. That matters because an OCR tool that returns a plain-text transcript is useless when you have to submit the document itself — you would have the words and no longer have the certificate. Here you get both: the same file to submit, now with text you can search.
When OCR helps, and when it will not
OCR works well on printed text that was scanned cleanly and straight. It struggles with handwriting, with photographs taken at an angle, with faded carbon copies, and with very low-resolution scans where the letters have blurred into each other. If your scan is hard for you to read, it will be hard for OCR too. Scanning at 300 DPI in greyscale, flat and square to the page, makes far more difference to accuracy than anything the software can do afterwards. A PDF that already has a text layer is returned untouched rather than re-processed, since re-running OCR on recognised text only introduces errors.
Why this one uploads and the rest do not
Every other tool on this site runs entirely inside your browser and your file never leaves your device. OCR is the exception. The recognition engine is tens of megabytes and slow enough on a mid-range phone to be unusable, so this runs on our server instead. Your file is uploaded over an encrypted connection, processed, and deleted automatically within fifteen minutes — nothing is kept, nothing is logged beyond the fact that a job ran. If you would rather not upload a sensitive document at all, the honest answer is not to use this particular tool; the rest of the site will never ask you to.
Frequently asked questions
- Will OCR change how my document looks?
- No. The page images are kept exactly as they are and the recognised text is added behind them, invisible. The document looks identical — you can just search and select text in it now.
- Does this work with Hindi?
- Yes. English and Hindi are both supported, and you can select both at once for documents that mix them, which many Indian forms do.
- Is my file uploaded?
- Yes, and this is the only tool here that uploads. OCR is too heavy to run in a browser. Your file is processed and then deleted automatically within 15 minutes.
- Why is the text wrong in places?
- OCR accuracy depends almost entirely on scan quality. Faded print, handwriting, skewed pages and low-resolution scans all reduce it. Rescanning at 300 DPI, flat and straight, helps far more than any setting here.
- Can it read handwriting?
- Not reliably. The engine is built for printed text. Handwritten notes, signatures and filled-in form fields will usually come out wrong or be skipped.
- What if my PDF already has text in it?
- It is returned unchanged. Running OCR over text that is already recognised can only introduce mistakes, so the tool detects that case and skips the work.
- How long does it take?
- A few seconds per page. A long document is queued and processed in the background, and the page shows its progress while it runs.
