What PDFWix is

PDFWix is a free online toolkit for PDF and image tasks, available on web, Android, and iOS. Its PDF tools cover merging, splitting, compression, conversion, editing, signing, security, repair, page organization, form filling, watermarks, redaction, metadata editing, and OCR. Image tools handle compression, resizing, cropping, watermarking, and format conversion. The Free web app plan costs nothing and includes more than 35 PDF tools, with no daily task limits, watermarks, or signup requirement. Most tools run in the browser using WebAssembly; Protect PDF and Unlock PDF instead process files on PDFWix servers. The service says those server-processed files use TLS 1.3, are handled in memory, and are not written to disk. Browser tools are subject to device memory, while Protect and Unlock accept files up to about 25 MB per request; another FAQ answer gives different figures. PDFWix says it is not HIPAA certified and recommends browser-based tools for protected health information. It also describes an OAuth 2.1 remote MCP server for AI assistants such as Claude. Its REST API is pre-launch, with a waitlist open and pay-as-you-go pricing planned.
