The simplest way to edit a PDF on Windows
Windows 11 comes with a built-in PDF editor in Microsoft Edge that handles the most common edits — adding text, drawing, and highlighting — without installing anything else. Open your PDF in Edge, click the pencil icon in the toolbar, and you can type directly into forms, mark up pages, or add notes. When you finish, save the file with File > Save As.
If you need to do more than mark up a document — like rearrange pages, delete sections, or merge multiple PDFs — you will need a dedicated tool. The choice depends on whether you want to pay, how often you edit PDFs, and what kinds of changes you make most.
Key Takeaways
- Microsoft Edge's built-in editor handles text, highlighting, and form-filling for free and requires no installation.
- Adobe Acrobat Reader (free version) lets you comment and highlight but cannot change the actual PDF content.
- Paid tools like Adobe Acrobat Pro or Nitro allow you to edit text, rearrange pages, and merge files, but cost money monthly or as a one-time purchase.
- Free desktop tools like PDFtk or online editors work for straightforward jobs but may have limits on file size or the number of edits per month.
- The right tool depends on whether you edit PDFs daily, what changes you need to make, and whether you want to pay for the feature.
Using Microsoft Edge for basic edits
Open your PDF file in Microsoft Edge by dragging it into the browser or right-clicking it and selecting "Open with" > "Microsoft Edge". Once the PDF loads, look for the pencil icon in the top toolbar. Click it to enter edit mode.
In edit mode, you can add text boxes anywhere on the page by clicking where you want to type. You can also highlight text, draw freehand marks, and add typed notes. The toolbar shows options for pen color, eraser, and undo. These changes exist only in Edge until you save the file — the original PDF on your computer stays unchanged unless you overwrite it.
When you are done, go to File > Save or File > Save As. If you choose Save As, you can give the file a new name or save it to a different folder. Edge saves your changes back into the PDF format, so the file stays compatible with any other program that reads PDFs.
When you need more control: paid desktop tools
Adobe Acrobat Pro is the industry standard for serious PDF work. It costs about $180 per year or $20 per month. With it, you can edit text directly (not just add boxes), delete or rearrange pages, merge multiple PDFs into one, split a PDF into separate files, and compress large files to make them smaller. You can also fill forms, sign documents, and protect PDFs with passwords.
Nitro is a cheaper alternative at roughly $120 per year. It handles most of the same tasks — text editing, page rearrangement, merging, and form-filling — but some advanced features cost extra. Nitro also integrates with Microsoft Office, so you can convert Word documents to PDF directly from within Word.
Both tools let you edit text that already exists in the PDF, which Edge cannot do. If your PDF contains text you need to change, delete, or move around, you need one of these paid options or a free alternative.
Free desktop tools for occasional use
PDFtk Free is a command-line tool that runs on Windows and handles page splitting, merging, rotating, and removing. It does not have a graphical interface — you type commands into the Windows Command Prompt — so it is best for people comfortable with text-based instructions. It is genuinely free and has no limits on file size or number of edits.
LibreOffice Draw is part of the free LibreOffice suite. You can open a PDF in Draw and edit it like a document, adding and changing text, moving objects around, and deleting content. The downside is that LibreOffice sometimes reformats the PDF when you open it, so the layout may shift slightly. It works best for PDFs with straightforward layouts.
Both of these are free and have no monthly fees, but they require more patience than paid tools. PDFtk requires typing commands, and LibreOffice Draw may need you to fix formatting after you edit.
Online PDF editors and their trade-offs
Web-based tools like Smallpdf, ILovePDF, and PDF.io let you upload a PDF, make changes in your browser, and read the result. Most offer a free tier with limits — usually a few edits per day or per month, or a file size cap of 50 MB or so. Paid plans remove these limits.
The main advantage is that you do not install anything on your computer. The main disadvantage is that you are uploading your PDF to someone else's server. If your PDF contains sensitive information — medical records, financial data, legal documents — you should check the website's privacy policy before uploading. Some services delete files after a few hours, but others may keep them longer.
Online editors work well for one-off jobs or when you are on a computer where you cannot install software. For regular use or sensitive documents, a desktop tool is safer.

How to choose the right tool for your situation
Start with Microsoft Edge if you only need to highlight, annotate, or fill in forms. It is already on your computer, costs nothing, and handles these tasks well. If Edge does not do what you need, move to the next step.
If you edit PDFs more than once a week and need to change text or rearrange pages, a paid tool like Adobe Acrobat Pro or Nitro is worth the cost. The time you save compared to free tools pays for itself quickly. If you edit PDFs rarely, try LibreOffice Draw or an online editor first — they are free and handle most jobs.
If your PDFs contain sensitive information, avoid uploading them to online tools. Use a desktop tool instead, whether free or paid. If you work with very large files or need advanced features like batch processing, Adobe Acrobat Pro is the most reliable choice.
Frequently Asked Questions
Can I edit a PDF directly in Microsoft Word?
Word can open some PDFs and convert them to editable documents, but the conversion often breaks the layout, especially for complex PDFs. Right-click a PDF, select "Open with" > "Word", and Word will attempt the conversion. Check the result carefully — text may move, images may shift, and formatting may change. For straightforward PDFs with mostly text, it sometimes works well. For anything with a specific layout, use a dedicated PDF tool instead.
What if my PDF is password-protected?
If the PDF is locked to prevent editing, you need the password to unlock it. Most paid tools and some online editors have an unlock feature where you enter the password and they remove the restriction. If you have forgotten the password and own the document, contact whoever created it. If someone else locked it intentionally, you cannot legally remove the protection.
Can I edit a scanned PDF (a PDF made from a photograph of a document)?
Scanned PDFs are images, not text, so standard PDF editors cannot change the words. You need optical character recognition (OCR) software to convert the image to editable text first. Adobe Acrobat Pro includes OCR. Some online tools also offer it. After OCR converts the image to text, you can edit it like a normal PDF. The conversion is not always perfect, especially for poor-quality scans, so check the result carefully.
Is it safe to use free online PDF editors with confidential documents?
It depends on the service and your comfort level. Read the privacy policy to see how long files are kept and whether they are encrypted during upload. Many reputable services delete files after a few hours and use encryption, but you are still trusting a third party with your data. For highly sensitive documents, use a desktop tool that stays on your computer instead.
Why does my edited PDF look different when I open it again?
Different programs display PDFs slightly differently depending on how they render fonts and spacing. If you edited the PDF in one tool and opened it in another, minor shifts in text position or line breaks are normal. If the changes are major, the tool may have reformatted the PDF during editing — LibreOffice Draw does this sometimes. To avoid this, stick with one tool for editing and opening the same PDF.
