Why You Need a Good PDF Tool
PDFs are everywhere — contracts, invoices, eBooks, forms, manuals. While Adobe Acrobat is the industry standard, its subscription cost makes it overkill for most home users. The good news: there are excellent free alternatives that handle the most common PDF tasks without any cost or limitations.

1. PDF24 Creator
PDF24 is arguably the most feature-complete free PDF tool available. It bundles over 25 utilities: merge, split, compress, convert, protect, rotate, and more — all in a clean desktop interface. It also installs a virtual PDF printer, letting you "print to PDF" from any application. There are no watermarks, no page limits, and no subscription.
2. Sumatra PDF
If you just need to read PDFs quickly without bloat, Sumatra PDF is unbeatable. It launches almost instantly, supports keyboard navigation, and also reads ePub, MOBI, XPS, and comic book formats. It's tiny (~10 MB) and available as a portable app — great for USB drives.
3. PDFsam Basic
PDFsam (PDF Split and Merge) does exactly what the name says, and does it well. The Basic (free) version lets you split PDFs by page ranges, merge multiple PDFs into one, rotate pages, and extract pages. The interface is straightforward, and there are no watermarks on output files.
4. LibreOffice Draw
LibreOffice Draw is part of the free LibreOffice suite and can open PDF files for direct editing. It's not perfect for complex layouts, but for editing text, moving images, or adding annotations on a simple PDF, it gets the job done without any cost.
5. Okular
Okular is a powerful document viewer from the KDE project. Beyond basic viewing, it offers rich annotation features: highlights, sticky notes, inline text notes, and stamps. Annotations are saved without permanently modifying the original PDF, which is useful for collaborative review workflows.
6. iLovePDF (Web-Based)
For quick, one-off PDF tasks without installing anything, iLovePDF is a solid web-based option. Compress a PDF, convert Word to PDF, split pages — it handles common tasks fast. Be mindful of uploading sensitive documents to any online service.
7. NAPS2
NAPS2 (Not Another PDF Scanner 2) is a free scanner utility that makes scanning documents to PDF incredibly easy. It supports batch scanning, OCR (optical character recognition) to create searchable PDFs, and outputs clean, well-formatted files. If you have a scanner and work with physical documents, this is essential.
