Open a file, use a tool, download the result. That's it. WHAT'S INSIDE ✅ Edit PDF — rotate, delete, and reorder pages; insert text and images ✅ Annotate PDF — highlight, underline, freehand drawing, notes, stamps ✅ Redact PDF — permanently black out sensitive content ✅ Watermark — stamp text watermarks across every page ✅ Page numbers — add page numbers with custom position and format ✅ Compress PDF — shrink file size (keep text, or rasterize + JPEG) ✅ Merge PDF — combine multiple files in your chosen order ✅ Split PDF — split every N pages or by custom ranges, zipped for you ✅ Extract pages — pull out just the pages you need ✅ Sign PDF — draw or type a signature, drag-and-drop it onto the page ✅ PDF → JPG — render every page as an image (zipped if multiple) ✅ PDF → Word (.docx) — extract text, line by line ✅ PDF → Excel (.xlsx) — reconstruct tables from text coordinates ✅ PDF → PowerPoint (.pptx) — one slide per page, as an image ✅ AI Assistant (optional, not offline) — summarize or ask questions about a PDF via an AI endpoint you configure with your own API key AN HONEST LIMITATION The Word/Excel/PowerPoint conversions run fully offline, so they preserve content, not pixel-perfect layout — Word output is line-based text, Excel reconstructs tables from text position (works best on already-tabular PDFs), and PowerPoint places one page-image per slide. True layout-perfect conversion needs a heavy server-side OCR/layout engine, which isn't something we can (or want to) run silently in your browser. PRIVACY FIRST • 14 of 15 tools never send your file anywhere — everything happens locally in your browser (some tools use a local WebAssembly module for speed) • The one exception, AI Assistant, is clearly labeled, opt-in, and requires your own API key before anything leaves your browser • No analytics and no session recording — BigPDF collects nothing • No content scripts and no access to the pages you browse • No account required for the free tier • Full privacy policy: https://getpekka.com/en/privacy/bigpdf/ SIMPLE PRICING • 5 free tool uses per week (all tools share one pool, resets weekly) • Monthly — $9 / month, cancel anytime • Yearly — $49 / year (save 55% vs monthly) ⭐ most popular • Lifetime — $99 one-time, no renewal Paid plans remove the weekly limit across all 15 tools. PERFECT FOR • Anyone who needs to edit, sign, or convert a PDF without uploading it to a random website • Students and professionals merging, splitting, or extracting pages regularly • Anyone who wants a quick redaction or watermark tool without installing desktop software • Multilingual users — the interface is available in more than 50 languages ## Rankings - #65,538 — Overall - #161 — sign ## Permissions and access ### Permissions - `storage` - `https://api.gethogrider.com/*` - `https://ollama.com/*` ## Safety - **Risk impact:** Low risk impact - **Risk likelihood:** High risk likelihood ### Analysis details - Request access to the following domains: gethogrider.com, ollama.com - This extension was recently updated in the past month.
