Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
LightPDF is a PDF service for individuals and organizations that need to merge, split, compress, convert, edit, annotate, sign, protect, and unlock PDF files. Its tools also include OCR and AI-powered document assistance. The product is suited to users who want web-based PDF help with the option to work across Windows, macOS, iOS, Android, a Chrome extension, and an API. The free plan makes it accessible for occasional tasks, while paid plans expand file handling, storage, and platform access.
Pricing is structured around a free plan and three paid options. The Free Plan is web only, supports files up to 10MB, and includes cloud storage for 1 year and 5 files. The Monthly Plan costs $5.99 per month and adds web, mobile, and desktop access, unlimited maximum file size, unlimited cloud storage, and 1,000 AI credits per month. The Yearly Plan costs $15.99 per year with the same core paid features and a 3-day free trial. The Lifetime Plan costs $39.99 one-time and includes 40,000 lifetime AI credits. According to the published plans, paid access is the practical choice for larger files and regular multi-device work.
LightPDF covers a wide range of common PDF workflows rather than focusing on a single editing task. Users can combine two or more PDFs, extract pages, convert documents to Word, PowerPoint, Excel, images, and other formats, add annotations, and apply electronic signatures or passwords. Cloud storage and API access also support broader workflows. However, the free tier is limited by platform, file size, and storage capacity, and the available feature coverage may be less comprehensive for users comparing specialized PDF editors. Choose LightPDF for inexpensive web assistance and broad format support; look elsewhere if you need a more fully verified feature set for advanced PDF work.
