PDF Tools

Compress, merge, split and convert PDF documents online for free. Support for large files up to 100MB. No signup, no watermark.

PDF documents are the universal standard for sharing formatted content across devices, operating systems, and industries. Whether you are a student submitting assignments to a university portal, a professional preparing contracts and reports, or a business archiving records for compliance, you need reliable tools to compress, merge, split, and convert PDF files without compromising quality or privacy. FreeToolkit's PDF suite uses a hybrid processing architecture — lightweight operations like page extraction run directly in your browser via WebAssembly for maximum speed, while resource-intensive tasks like multi-file merging and high-ratio compression leverage ephemeral server processing where files are immediately purged from volatile memory after download. Every PDF tool supports files up to 100 MB for free (500 MB with Pro), requires zero registration, and never applies watermarks to your output. Our compression engine uses advanced image downsampling, font subsetting, and stream-level deflate recompression to achieve up to 90% size reduction while preserving sharp vector text and embedded hyperlinks.
