PDF editing should not cost $20 a month. Adobe Acrobat Pro is a great product, but for most people who just need to fill a form, add a signature, merge a few files, or annotate a document, it is massive overkill. And plenty of the free online PDF editors out there require uploading your documents to some company's server, which is a non-starter if you are working with sensitive information.
The good news is that several free, offline PDF editors handle the most common tasks perfectly well.
Here are the best options that work right on your computer without an internet connection.
LibreOffice Draw
LibreOffice is a full office suite that competes with Microsoft Office, and its Draw application handles PDF editing surprisingly well. You can open any PDF in Draw and edit the text, images, and layout directly. It is not perfect for complex PDFs with fancy formatting, but for simple documents, it works great.
The text editing is genuine text editing, not just overlaying a text box on top of the existing content.
You can select, delete, retype, and reformat text within the document. You can also add images, shapes, arrows, and text boxes anywhere on the page.
LibreOffice runs on Windows, Mac, and Linux. The entire suite is free and open source with no limitations, no ads, and no registration required. For people who already use LibreOffice for word processing or spreadsheets, this is the most convenient option since you already have it installed.
The downside is that Draw sometimes struggles with the formatting of complex PDFs.
Fonts may shift, spacing can change, and embedded graphics occasionally render incorrectly. For simple edits, it is excellent. For preserving pixel-perfect layouts, look at the other options below.
PDF-XChange Editor (Windows)
PDF-XChange Editor is the most feature-rich free PDF editor available for Windows. The free version includes annotation tools, text highlighting, stamps, comments, form filling, digital signatures, and OCR (optical character recognition) for scanned documents.
The annotation tools are particularly strong. You can highlight, underline, strikethrough, draw freehand, add sticky notes, and insert custom stamps. The typewriter tool lets you add text anywhere on a PDF, and the measurement tools are useful for technical documents.
OCR is the standout feature. If someone sends you a scanned PDF (essentially an image of a document), PDF-XChange can recognize the text and make it searchable and selectable.
This feature alone would cost money in most other editors.
The free version does add a small watermark to documents if you use certain premium features (like direct text editing or page removal), but the core annotation, commenting, and form-filling features are completely watermark-free. For most tutorial and office use, you will never see a watermark.
Foxit PDF Reader
Foxit has positioned itself as the main alternative to Adobe Reader, and their free reader includes solid editing capabilities.
You can annotate, highlight, add text comments, fill forms, sign documents, and collaborate through shared reviews.
The interface is clean and familiar, resembling Microsoft Office with a ribbon-style toolbar. If you are coming from Adobe Reader and want something similar but with more features, Foxit feels like home immediately.
Form filling is particularly smooth. Foxit automatically detects form fields and lets you tab between them like a web form.
It handles both interactive PDF forms and flat forms (where you position text boxes manually over the printed fields).
Foxit runs on Windows, Mac, and Linux. The reader is completely free and handles the most common PDF tasks well. If you need advanced features like full text editing, page management, or redaction, those require the paid Editor version, but the free Reader covers 90% of what most people need.
Okular (Linux, Windows, Mac)
Okular is KDE's document viewer, and it is excellent for PDF annotation on Linux.
It supports highlights, inline notes, freehand drawing, stamps, and typewriter annotations. All annotations are saved within the PDF and can be viewed in any other PDF reader.
The review tools let you add pop-up notes attached to specific text selections, which is great for providing feedback on documents. The bookmark feature lets you mark important pages for quick navigation in long PDFs.
Okular is lightweight and opens PDFs faster than most alternatives. It does not do full text editing (you cannot change the existing text in a PDF), but for annotation, form filling, and document review, it is one of the best free options available, particularly on Linux where choices are more limited.
On Windows and Mac, Okular is available through the Microsoft Store and Homebrew respectively, though it works best in its native Linux environment.
Inkscape (Free, Open Source)
Inkscape is primarily a vector graphics editor (think free alternative to Adobe Illustrator), but it handles PDF editing in a unique way.
It imports each page of a PDF as a vector graphic, giving you complete control over every element on the page.
This approach means you can edit anything: text, images, shapes, lines, and formatting with precision. Need to change a font, resize an image, or rearrange elements on the page? Inkscape handles it. The trade-off is that it works one page at a time, so it is not ideal for multi-page documents.
For single-page PDFs that need detailed editing, like flyers, certificates, or forms, Inkscape offers more control than any other free tool.
It runs on Windows, Mac, and Linux, and the entire application is free and open source.
The learning curve is steeper than dedicated PDF editors because Inkscape is a full graphic design application. But if you are already familiar with vector editing, or willing to spend an hour learning the basics, the editing power is remarkable for a free tool.
Which One Should You Use?
For annotation and form filling: PDF-XChange Editor on Windows, Foxit Reader on Mac.
Both have strong annotation tools that work completely offline.
For editing text in simple PDFs: LibreOffice Draw. It lets you change existing text directly, which most free editors do not.
For scanned PDFs that need OCR: PDF-XChange Editor. Free OCR in a desktop application is rare.
For precise, design-level edits: Inkscape. Nothing else free gives you this level of control over every element.
For Linux users: Okular for annotation, LibreOffice Draw for text editing, Inkscape for design-level work.
None of these tools require an internet connection, and none will upload your documents to external servers. Your files stay on your computer, which is exactly how it should be.
