What it is

PDFWix is a free service for PDF and image work, with web, Android, and iOS platforms. Its PDF tools merge, split, compress, convert, edit, sign, secure, and repair files, and also 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 costs nothing and includes 35+ PDF tools, no daily task limits, no watermarks, and no signup requirement. Most tools run in the browser through 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 a device-memory limit, while Protect and Unlock accept files up to about 25 MB per request, with another FAQ giving different figures. PDFWix is not HIPAA certified. It lists a remote MCP server using OAuth 2.1 and a pre-launch REST API with a waitlist.
