Your file is deleted the moment it's done. The big PDF sites keep your bank statements and IDs on their servers. Here the original goes right after processing, the result after 45 minutes, or sooner, on your click.
Why photos in, not PDFs
This page only accepts photos of a document, never a finished PDF, and the data explains why that rule exists. In the 38 days we've been measuring, one of the handful of upload rejections logged sitewide was exactly the mismatch this page is built to avoid: someone uploaded an already-scanned PDF, a picture of text, not real text, to a tool that needed selectable text underneath. A scanned PDF has no hidden text layer to search; that's the whole reason OCR exists as a separate step. Feed OCR PDF a photo instead, and it builds that text layer for you rather than assuming one is already there. On usage: this exact page recorded one completed OCR job in the window we tracked (15 July, 21 August), against 257 real visitors to the site as a whole across 27 countries. That's a small number and we're not going to dress it up: a new tool starts quiet, and the number belongs here more than a rounded-up one.
What the OCR option does
Normally a scanned PDF is just a picture of the page, you cannot search it. Tick the OCR box before downloading and ScanReviver runs OCR over the cleaned pages and adds a hidden text layer underneath the image, so the PDF looks identical but the words become selectable and searchable.
- Select and copy text out of the PDF
- Search inside the document with Ctrl/Cmd-F
- Recognises English, Dutch, German, French, Spanish and Portuguese
- The page still looks exactly like your scan
Under the hood this is ordinary OCR text recognition: an online OCR reader that turns the picture of a letter into an actual, selectable letter. Already have a finished, already-scanned PDF file rather than a loose photo? This page only takes photos in, so run it through PDF to JPG first to get an image per page, then add OCR here the normal way.
How to make a searchable PDF
OCR is optional and off by default, because it adds some processing time. You turn it on for the pages that are text you want to search.
- Upload your document photos and crop and clean them as usual.
- Tick โMake the PDF searchable with OCRโ before you export.
- Press Download PDF and wait a little longer while the text layer is built.
- Open the PDF and try selecting or searching the text.
Good to know
You upload photos, not a finished PDF, ScanReviver builds the searchable PDF for you from the cleaned pages. Clean, sharp text reads best; faint, blurry or handwritten text is harder for any OCR engine. Start from a tidy page with clean a scanned document or go straight to the multi-page flow with scan to PDF.
ScanReviver improves readability; it does not use generative AI and never rewrites text, changes numbers, edits dates or recreates signatures or stamps. Very dark shadows, text hidden under a finger, glossy glare and severe blur can still look imperfect, so always check the result before you rely on it.
A free PDF OCR online tool, not a program to install
This is a free OCR tool in the browser, not OCR PDF freeware you download and run on your own machine. The OCR runs on our own server, the original is deleted right after processing and the result within 45 minutes, so there is nothing to install and nothing left behind. What comes back is an ordinary PDF file any reader opens, just with an invisible text layer added inside it, and you get that searchable PDF online in a few seconds.
Want to OCR a PDF you already have?
If you want to OCR a PDF that already exists as a file, ScanReviver works from the photo side instead: you upload the page photos first, and the searchable text layer is added while the PDF itself is being built. To convert PDF scans, turn them into page images with PDF to JPG first; that is also how to make PDF files from old scans searchable.
The many ways to say "OCR a PDF"
As an online OCR tool for PDF pages it starts from document photos, since a scanned PDF has no text to recognise on its own. It is a PDF OCR converter built around photos, not a PDF to OCR converter that rewrites an existing file. Tick the box and the letters in the photos become real text; you can recognize text in PDF pages in English, Dutch, German, French, Spanish and Portuguese, with no charge per language and no watermark. The text OCR reads best is clean and sharp, so faint or handwritten lines may need checking. In Spanish this is called PDF a OCR.
Free OCR PDF output is what this page builds, up to 10 documents a day, and PDF OCR online free covers the whole flow: upload, recognise, download. Online OCR for PDF pages here also cleans each photo first, because a cleanup before recognition gives better text. The recognized words go straight into a hidden layer inside the file, so OCR PDF to text happens without a separate export, and you can still copy the text to another app later. Use OCR PDF online from any browser: every online OCR PDF job runs on our server, you get OCR free of charge, and the OCR converter adds nothing to the page. Like any decent PDF converter free of charge, it needs no account before the first document.
Once the searchable text layer is in, you can also translate the PDF into another language: the layout stays intact there too. Need the pages back out as sharp images instead, for diagrams or line art? PDF to PNG keeps the text edges crisp where a JPG would smear them. Want the gist of that same text instead of reading the whole thing? Summarize PDF writes a short summary once it has a text layer to read. Prefer to ask it specific questions instead? Chat with PDF answers directly from the document's own text. Copied that text out and a script or CSV import breaks on it for no visible reason? TextNinja's hidden characters tool shows exactly which invisible character is sitting in the text and where.
Common questions
Which languages does the OCR read?
English, Dutch, German, French, Spanish and Portuguese. The text layer covers those six languages; you do not have to pick one.
Can I upload my PDF to OCR it?
No. You upload photos of the pages and ScanReviver builds the searchable PDF from them; it does not take a finished PDF as input. OCR for PDF files you already have starts by turning their pages into images with PDF to JPG and uploading those. So OCR for PDFs, whether one page or many, always starts from images here.
Why is OCR off by default?
Because it adds processing time. Turn it on only for the pages whose text you actually want to search.
Will OCR change how the page looks?
No. The invisible text sits underneath the image, so the PDF looks exactly like your original photo after cleaning, but the words become selectable.
How do I make a PDF searchable with OCR?
Upload your photos, tick 'Make the PDF searchable with OCR' before downloading, and the text layer is added automatically. That is how to make a PDF searchable here, and how to OCR a PDF document of one page or thirty. How do you OCR a PDF from a phone photo? The same way, in the phone's browser. OCR and PDF happen in one step, with the text layer baked in as the file is built, so how to do OCR in PDF form needs no second export.
Is the result searchable in any reader?
Yes. An OCR PDF document opens and searches normally in any PDF reader, in Google Drive or in a phone's Files app. The OCR PDFs you get back are regular PDFs with an invisible, selectable text layer, so OCR PDF documents from here behave like any other file. That is all the OCR PDF format is.
What is PDF OCR?
PDF and OCR together mean optical character recognition applied to a PDF: the software reads the letters in a photographed or scanned page and writes them back in as real, searchable text, without changing how the page looks. With OCR text recognition PDF pages become searchable while looking exactly the same; thanks to OCR recognition PDF files you can only look at become files you can search.
Can I do OCR on a form?
Yes, as long as you photograph the form and upload the photo. The text layer covers the whole page including the form fields, in all six languages.
Can I OCR a PDF for free?
Yes, for up to 10 documents a day. Uploading photos, running OCR and downloading the searchable PDF costs nothing, with no account and no watermark, so you can OCR a PDF for free without a trial. PDF OCR free of charge covers all six languages.
Do I need a scanner or software?
No. Photograph the pages with your phone and this page becomes your PDF scanner, cleaning, straightening and adding the text layer in one pass, so there is no separate OCR scan step and you never have to scan PDF pages on a flatbed. There is no PDF OCR software to download and no PDF OCR program to install; it runs in the browser.
Can I get the text into Word?
Not in one step: OCR here builds a searchable PDF, not a Word file. If you need editable text in Word, convert that searchable PDF with PDF to Word afterwards, also free. That two-step route is a PDF to Word OCR workflow without the OCR software PDF to Word converters often ask you to buy.
Does going from PDF to OCR PDF change the file?
Only by adding the hidden text layer. PDF to OCR PDF here means uploading the page photos and ticking OCR, so the page looks the same and every word becomes selectable.
Can I OCR several pages into one file?
Yes. Upload the pages together, up to 10 at once in the box above (the full scanner on the home page takes up to 30); each one is cleaned, straightened and OCR'd, and they combine into one PDF with the text layer on every page.
Is there a video walkthrough of OCR on a scanned page?
Yes. Watch the free OCR PDF demo, a video showing a scanned page turn searchable.
Can the OCR read handwriting?
Not reliably. Handwritten text is harder for any OCR engine than clean printed text, and faint or blurry text is harder too. The text layer covers English, Dutch, German, French, Spanish and Portuguese.
Is this an OCR PDF scanner I can use without a physical scanner?
Yes. Photograph each page with your phone, upload the photos, tick the OCR box and download a searchable PDF. The pages are cleaned and straightened first, so a flatbed scanner is not needed.
