Why Choose PDF AI
PDF AI offers a complete set of free online PDF tools that cover every common task: merging multiple PDFs into one document, splitting a large PDF into individual pages, compressing file size for email attachments, and converting between PDF, Word, Excel, PowerPoint, and image formats.
Unlike many competing PDF tools, we do not require account registration, do not add watermarks to your files, and support uploads of up to 200 MB per task. Every tool is available immediately in your browser without downloading software or installing browser extensions.
Beyond basic conversion and merging, our platform includes tools for adding password protection, removing known passwords, rotating pages, reordering pages, adding watermarks, inserting page numbers, and adding signature images to documents. Whether you need to prepare a job application, organize scanned receipts, or finalize a contract, there is a tool for it.
For step-by-step instructions with practical examples, visit our PDF Guides & Tutorials section, which covers every tool in detail.
