PDF Tools by Renderlog

PDF Tools by Renderlog とは？

All the PDF tools you actually need — merge, split, compress, OCR scanned PDFs into searchable text, sign, unlock, and convert to Word — running entirely in your browser via pdf.js and WebAssembly. Files never touch a server. No signup, no ads, no upload limits, works offline after first load. Free forever. Built for anyone who's ever hesitated to upload a contract, ID scan, or salary slip to a "free" tool that quietly stores your files on someone else's machine.
