Category: PDF Editing & ProductivityVerified for 2025
Top Recommended Replacements
PDFgear
FREEBest Overall Free Nitro Alternative
Why we like it
100% free with no watermarks; features a unique 'AI Copilot' (ChatGPT-powered) to summarize and edit docs; provides 'True Text Editing' (modifying existing text directly).
Keep in mind
Text editing can occasionally be clunky with complex font layouts; lacking the deep enterprise admin portal of Nitro.
Stirling-PDF
FREEBest for Privacy & Developers
Why we like it
100% private and self-hostable; includes 50+ tools (OCR, Redaction, Security); open-source core allows for total data sovereignty.
Keep in mind
Requires basic technical knowledge to self-host (Docker/Server); the web interface doesn't allow 'In-Line' text editing like a word processor.
Foxit PDF Editor
Best Professional Rival
Why we like it
Superior collaboration tools and AI-driven automation (Smart Redact); better mobile support (Android/iOS) than Nitro; often 30-40% cheaper than Adobe.
Keep in mind
The perpetual license is limited to major versions; interface can feel cluttered with too many enterprise features.
PDF-XChange Editor
Best Value for Windows Power Users
Why we like it
The fastest PDF editor on Windows; highly granular controls for annotations and stamps; perpetual license is one of the most affordable in the industry.
Keep in mind
Windows only; the interface looks like legacy software from the 2010s; steep learning curve for advanced markup.
Wondershare PDFelement
Best Modern AI Experience
Why we like it
Strongest AI proofreading, translation, and summarizing tools; very user-friendly 'Modern' UI; handles complex forms and OCR with high accuracy.
Keep in mind
Free version adds watermarks; requires a subscription for the best AI-driven cloud features.
Drawboard PDF
FREEBest for Pen/Stylus Annotations
Why we like it
World-class 'Inking' experience; real-time collaboration on a shared canvas; best for architecture, engineering, and student note-taking.
Keep in mind
Not designed for heavy text editing or 'Acrobat-style' form creation; some advanced tools require a Pro subscription.
Okular
FREEBest Multi-Format Open-Source Viewer
Why we like it
Supports PDF, EPUB, Comics, and more; features basic annotation tools and 'Digital Signatures'; 100% free and cross-platform (Win/Mac/Linux).
Keep in mind
Lacks 'True PDF Editing' (you can add text, but you can't easily change existing PDF text); interface is purely functional.
Sejda PDF
FREEBest for Quick Web-Based Tasks
Why we like it
No installation required; allows 3 tasks per day for free; very intuitive interface for simple text changes and signing.
Keep in mind
Free tier has strict limits on file size (200 pages/50MB); privacy concerns with uploading sensitive data to an online server.
PDF24 Creator
FREEBest Offline Tool for Basic Needs
Why we like it
Completely free for business and personal use; features a 'Virtual Printer' and excellent file compression; 100% offline security.
Keep in mind
Windows only; lacks the AI summaries and advanced text-editing polish of PDFgear or Nitro.
SumatraPDF
FREEBest Lightweight Viewer
Why we like it
Fastest loading speeds in the industry; incredibly small file size; supports almost every document format.
Keep in mind
View and basic annotation only—cannot edit text or manage complex PDF forms.
