What PDFWix is
PDFWix is a free service for PDF and image tasks on web, Android, and iOS. Its PDF tools merge, split, compress, convert, edit, sign, secure, and repair files. Additional functions organize pages, fill forms, add watermarks and signatures, redact content, edit metadata, and perform OCR. Image tools handle compression, resizing, cropping, watermarking, and format conversion. The Free web app plan costs nothing, includes more than 35 PDF tools, has no daily task limits or watermarks, and requires no signup. Most tools run in the browser using WebAssembly. Protect PDF and Unlock PDF process files on servers; PDFWix says those files use TLS 1.3, stay in memory, and are not written to disk. Browser tools have device-memory limits, while Protect and Unlock accept files up to about 25 MB per request, although another FAQ gives different figures. PDFWix is not HIPAA certified. It also describes a remote MCP server with OAuth 2.1 and a pre-launch REST API waitlist.
