Edit a Scanned PDF for Free: OCR and Editable Text

Scanned PDF OCR checklist

0 of 10 complete · saved on this device

• 1. Write down one job before you open a tool: make the words in a scan selectable or searchable, save those words as a plain-text file, or change the words in the scan. Preview’s Embed Text page, Chrome’s computer PDF page, PDF24’s OCR page, and Stirling’s OCR guide describe text you can select, search, or copy. Sejda’s OCR page describes a searchable PDF or a plain-text file. Acrobat’s edit-scans article is the page that says the scan becomes an editable PDF copy you type in. That article does not say the steps are free. Changing text that is already in a born-digital PDF on a Mac stays on the Preview text guide. This page does not copy that markup procedure.
• 2. On a Mac, keep three Preview pages apart. The Embed Text page says Preview can recognize text in an image-based PDF, like a scan or a picture of a document, and embed the text in the document. The steps are: go to Preview, open a PDF, choose File > Export, and select Embed Text. Preview scans for text and embeds it so that it can be selected in any PDF viewer. The note says this option only appears if no text was previously recognized in the document. That page does not say you can type a replacement for a word in the scan. It does not display a price. The Live Text page is a different job: open a photo or image that shows text, then drag to select it and choose Copy Text. It says Live Text isn’t available in all regions or languages, and it points to the macOS Feature Availability webpage. It does not name File > Export or Embed Text. The annotate page checked the same day still says you can’t edit the text of a PDF in Preview. Its Text tool says to type your text, then drag the text box where you want it. That page does not name Embed Text, a scan, or OCR. The markup steps stay on the Preview text guide.

• 3. For Chrome on a computer, open the manage-PDFs page’s Computer version. On 5 November 2026 that page says you can open, search, and edit PDFs in Chrome, and that the viewer can highlight, annotate, or draw, add text, fill out and sign paperwork, and take personal notes. A separate paragraph says that when you use the Chrome PDF viewer, scanned PDFs of physical documents are automatically converted to be searchable and selectable using optical character recognition. After the conversion, you can highlight, search, copy, paste, and find text. The conversion is completed on your device without sending any data to Google or third parties. Add text, on the same page, is a separate control: select Add text, choose the font, style and color, and click where you want to add text. Download is With your changes or Without your changes, and Chromebook users select Save. The OCR paragraph does not say the recognized words become a paragraph you retype. The page does not display a price. It does not say free.

• 4. For Microsoft Edge, the PDF reader article checked on 5 November 2026 lists view and print, basic form filling, a table of contents, page view, caret browsing, inking, highlight, text notes, and read aloud. Its reading-features sentence includes search among Zoom, Rotate, Fit to page or width, and jump to page. The article says JavaScript forms aren’t supported and that XFA isn’t supported. It does not name OCR, optical character recognition, or a scanned document. It does not display a price. Filling a form that already has fields stays on the Chrome and Edge fill guide. That guide is not this OCR procedure.

• 5. For PDF24’s online OCR tool, use the OCR page’s own sentences. The page title says the tool is 100% free and online. The badges on the page say Free, Online, No limits, and Secure. The heading says to make scanned documents and photos searchable with text recognition, copy text from them, and save as PDF/A with deskewed, cleaned pages. The steps say to select the files or drop them in the file box, modify the settings, and start the OCR, then download the new searchable PDF files. The settings named on that page are save as PDF/A, remove artefacts and noise, deskew pages, set meta information, and join to a single output file. The page says you do not need to install software, that the text is recognized on PDF24 servers in the cloud, and that the files and results are deleted from the server after a short period of time. File transmissions are SSL secured. A warning on the page says OCR is very time-consuming and says to also use PDF24 Creator as an alternative OCR solution. The page does not say the recognized words can be retyped in the scan. It does not mention advertising. It does not display a dollar amount. It does not print a one-hour deletion time.

• 6. For PDF24 Creator, keep the download page apart from the online OCR page. On 5 November 2026 the download page says Creator is free Windows software for private and business use, with a PDF printer, working offline so files stay on your PC. Its PDF OCR line says to recognize text in PDF and image files via OCR and create PDF files with a text layer. The free answer says Creator can be used completely free of charge and without any restrictions, including by companies, authorities, and agencies. The same page says Creator can only be installed on Windows, and that Linux and Mac are not currently supported. It says Creator works offline, files remain on the PC, and files are not uploaded to the internet. The page prints latest version 11.32.0 and the line 2026-11-02 Version 11.32.0. The download rows name Windows 11 and Windows 10. A separate row for version 9.20.0 says that version does not include the Toolbox, OpenJDK, and Webview2. That row does not say it removes the PDF OCR line. The page does not say the text layer can be retyped. It does not say the online OCR tool and this desktop line are the same control. The tools homepage, checked the same day, says all PDF24 tools are free of charge and without any restrictions, and that this is achieved via some advertising on the web pages. It says the online tools process files on PDF24 servers and that files are removed after a short time. It points to Creator when files should remain on the PC. The homepage does not name OCR or a text layer. Its advertising sentence is not the OCR page’s “No limits” badge.

• 7. The PDF24 edit page is a third page. Its title says 100% free and online, and its badges say Free, Online, No limits, and Secure. It says you can write on PDF pages, insert images, shapes, and signatures, add comments, black out content, rearrange pages, and fill in forms. A tip says to convert a PDF to Word to edit the text. The text-editing answer says the best way to change the text is to convert the PDF to Word, edit in Word, and convert the Word file back to PDF. The page says the app runs on PDF24 servers in the cloud and that files and results are removed after a short time. It does not name OCR, a scanned document, or a text layer. It does not display a dollar amount. This guide does not treat that Word tip as an OCR step.

• 8. For Sejda, use the OCR page checked on 5 November 2026. The subheading says the page shows how to OCR convert PDF documents, for free. Step 1 is to select the PDF. The page says files are transferred safely over an encrypted SSL connection, that documents stay private, and that they are permanently removed after processing. It says Sejda Desktop offers the same features as the web service and converts the documents locally. That sentence does not say Desktop is free and does not display a dollar amount. Step 2 is to select the language. Step 3 is to select the output formats, a searchable PDF and/or plain text. The searchable result is described as a PDF that contains text, where the invisible text is overlayed on the original images at the correct locations. The other output is a plain-text file containing just the text. The page says higher-resolution documents lead to better results and says not to compress scans before OCR. It says it cannot guarantee 100% accuracy, that this is a best-effort approach, and that characters may be incorrect. It does not say you can retype a word inside the scan. It does not print an hourly cap or a page cap.

• 9. For Stirling PDF, leave each sentence on its page. The documentation homepage says Stirling is a private, open-source PDF editor, and the desktop card says it works offline. The homepage does not name OCR and does not display a dollar amount. The functionality page names OCR / Cleanup scans as make scanned PDFs searchable and clean them up. The same page names PDF Text Editor as edit the existing text and images in a PDF, and Add Text as type text anywhere on a page. Those are not the OCR sentence. It says not every tool is available everywhere, and that in the desktop app tools with a cloud badge need Stirling Cloud or a server. It does not mark OCR with that badge in the list. The OCR guide says OCR finds the text in scanned or photographed pages and adds it to the PDF so you can search, select, and copy it. The steps are: select one or more PDFs and open OCR / Cleanup scans, choose every language in the document, pick an OCR mode and any processing options, then click Process OCR and Review, check the result, and download it. Auto, the default, skips pages that already have text. Force OCRs every page and replaces any existing text. Strict stops if any page already has selectable text. The guide says that in the desktop app, OCR usually needs Stirling Cloud or a server. The “Where your tools run” page lists OCR under tools that usually need Cloud or a server. Its Local Only section says every tool runs on the computer and nothing is uploaded, and that a tool the built-in engine cannot run shows a cloud badge. Its Stirling Cloud section says running tools by hand doesn’t use credits. That credits sentence does not name OCR. The languages page says the OCR tool can offer only languages whose Tesseract language pack is installed on the server, that the standard Docker images include English, German, French, Portuguese, and Simplified Chinese, and that the ultra-lite image has no OCR. It says Stirling uses OCRmyPDF in the standard and fat images and falls back to Tesseract otherwise, and that the processing options work only with OCRmyPDF. None of these pages says the OCR result is a paragraph you retype. None displays a dollar amount.

• 10. For Acrobat, keep the edit-scans article and the recognize-text article apart. The edit-scans article, last updated on the page Oct 22, 2026, says to open the scanned PDF and select Edit. It says Acrobat automatically applies OCR and converts the document to an editable PDF copy. Then select the text element you want to edit and start typing. It says the new text matches the original font in the scanned PDF. On Windows, save with Menu > Save as. On macOS, save with File > Save as. The tips say to double-check the OCR text before editing, and they name Scan & OCR > Recognize Text as the rescan. They also say to minimize edits to tables, graphs, or images, and to keep a copy of the original file. The recognize-text article, also last updated Oct 22, 2026, says a scan contains only image data, not searchable text, and that OCR converts image text into selectable, searchable text. Its steps are All tools > Scan & OCR, In this file, a page range and a language, optional Settings, then Recognize Text. It says Acrobat creates a searchable text layer. A try-it line on both articles says “Make your scanned document editable in a few simple steps.” The recognize-text steps say a searchable text layer. This guide does not merge that line with those steps. Neither article says the steps are free, names Acrobat Reader, or displays a dollar amount. This guide did not open Acrobat and did not save a file.
