Free Online PDF, Document, Image & AI Tools
PDF Master is a lifetime-free platform of online tools that help you work with PDFs, documents, images, and AI without installing anything. Whether you need to merge PDF files, split a large document, compress a PDF to fit an upload limit, or convert a PDF to Word, you can do it online in seconds. Your files are processed securely and never leave your device — a level of privacy that traditional desktop software and many online converters simply cannot match.
Every tool is genuinely free. There are no subscriptions, no watermarks stamped on your output, and no daily caps designed to push you toward a paid plan. You can browse the full catalogue of tools or jump straight into a category below.
Essential PDF Tools
The core PDF tools cover the tasks you reach for every day. Combine reports and chapters with Merge PDF, pull out the pages you need with Extract Pagesor remove the ones you don't with Delete Pages. Shrink heavy files with Compress PDF without sacrificing readability, fix orientation with Rotate PDF, and tidy up the structure with Organise PDF. Because these use audited open-source libraries, processing is instant and your documents stay private.
Document Conversion
Need to move between formats? Our document conversion tools preserve your layout as faithfully as possible. Turn a PDF into an editable document with PDF to Word, or go the other way with Word to PDF. Extract tables into a spreadsheet using PDF to Excel, rebuild a deck with PDF to PowerPoint, or render a web page to a print-ready file with HTML to PDF. Fonts, tables, and images are carried across so the result looks like the original.
Image Tools
Working with scans and graphics is just as easy. Combine photos into a single document with Image to PDF, export pages as pictures with PDF to JPG, or shrink large photos with Image Compressor. We support PDF, DOCX, XLSX, PPTX, JPG, PNG, WEBP, and HTML, so almost any file you encounter has a home here.
AI-Powered Document Tools
For dense or lengthy files, our AI tools turn documents into answers. Get the gist of a long report with AI Summariser, or ask questions directly with Chat with PDF. They're ideal for research papers, contracts, manuals, and meeting packs where reading every page isn't practical.
Security, Signing & Privacy
Sensitive documents deserve real protection. Add a password and encryption with Protect PDF, remove one you own with Unlock PDF, and permanently remove confidential content with Redact PDF. You can also sign a PDF by drawing, typing, or uploading a signature, and add a watermark to mark drafts or assert ownership.
