About DocDox

DocDox is a suite of free, browser-based document tools built for people who need professional-grade utilities without the subscription cost or privacy risk. Every tool runs entirely in your browser using WebAssembly and modern JavaScript — your files are processed locally on your device and are never sent to any server.

We cover the three document tasks people need most: PDF tools for merging, splitting, compressing, editing, and converting; image tools for compression, format conversion, resizing, and AI background removal; and text & AI tools for summarization, word counting, and case conversion. All 18 tools are free, require no account, and impose no server-side file size limits.
