Oxna – Free PDF Reader & Local PDF Tools

100% free, private PDF toolkit in your browser. Merge, split, edit, sign, OCR, redact, and ask OxnaAI with page citations.

Oxna puts its free PDF tools one click away in Chrome. Click the Oxna button in the toolbar to open any of the 53 tools on oxna.ai, or search for the one you need. Right-click a page for three shortcuts: Ask OxnaAI and Auto-Highlight, Annotate and Comment, and the full list of tools. The tools cover everyday PDF work: editing and annotating, signing, combining and splitting files, converting to and from other formats, and making scanned pages searchable. Ask OxnaAI answers questions about a PDF and shows the page each answer comes from, or highlights every mention of a word and adds your comment. Private by design The tools run in your browser, so your PDF is not uploaded to Oxna. When you ask OxnaAI, your question and the text it reads are sent to the AI service to get an answer. The extension itself reads nothing from the pages you visit and collects no data. It asks for one permission, for the right-click menu. Free No account, no subscription and no adverts. Oxna also makes a desktop PDF reader and editor for Mac, Windows and Linux: oxna.ai/pdf/download.
