The best free PDF editors for Windows in 2026
PDF editing used to mean paying Adobe. It doesn't anymore. The catch: half the free PDF editors out there are ad-stuffed, watermarked, or trial-limited. We tested every major option. Seven were actually worth installing.
1. SwiftPDF — Editor's Choice
Free. Installer is about 12MB. Grade: A+.
SwiftPDF is the top pick. It handles text editing, image replacement, page management, annotations, form filling, batch processing, and conversion — all offline, all free. The interface is clean, startup is instant, and there's no account. For 99% of people, this is the only PDF tool you need.
2. Adobe Acrobat Reader (free version)
Free with limits. Installer ~600MB. Grade: B.
Adobe's free Reader handles viewing, basic comments, and form filling well. The catch is real editing is locked behind the Pro subscription at $22.99/month. The install is huge, it updates constantly, and it forces an Adobe account. Fine for reading, frustrating for editing.
3. LibreOffice Draw
Free, open source. ~350MB (comes with the full suite). Grade: B+.
LibreOffice Draw can open PDFs and treat them as vector graphics. It works well for text-heavy documents. Complex layouts with weird formatting sometimes come out looking strange.
4. PDF24 Creator
Free. ~60MB. Grade: B.
PDF24 is a solid toolbox for creating new PDFs, converting between formats, and combining documents. Less capable than SwiftPDF for deep text or image editing, but a good pick if you mostly create PDFs from other files.
5. PDFsam Basic
Free. ~45MB. Grade: B-.
PDFsam is a one-trick app: splitting and merging. It does that reliably. If page-level operations are all you need and the dated Java UI doesn't bother you, it's a fine secondary tool.
6. Foxit PDF Reader
Freemium. ~180MB. Grade: B-.
Foxit has been around forever and remains capable, with some basic editing in the free tier. The free version has gotten more limited over time, and the installer has historically tried to bundle extra software — watch the install wizard carefully.
7. Sumatra PDF
Free, open source. ~5MB. Grade: B.
The lightest option here. Under 5MB, instant launch, and excellent for reading long PDFs. Zero editing features — it's a viewer, full stop. If you just need to read big manuals, nothing beats it.
Bottom line
For actual editing, install SwiftPDF and stop looking. It's free, fast, private, and does what most paid tools do. Pin it to the taskbar and you're set.
