PDFToolWorks offers twelve focused PDF tools that run entirely in your web browser. There is no account to create, no file is uploaded to a server, and no surprise download charge. The project started from a simple frustration: most free PDF sites quietly upload your documents, cap you after a couple of tasks, or push a subscription at the download step.
Every tool on this site processes your files on your own device, using standard browser technology. When a file is too large for your phone or an old laptop, the tools say so honestly instead of failing silently.
