Best free PDF tools in 2026
Most "free" online PDF tools upload your document to a server, cap the number of files, or stamp a watermark on the result. The picks below do none of that: every one runs entirely in your browser, so your files never leave your device — and there's no sign-up, no watermark and no page limit.
