How it works
The PDF Reader displays any PDF file directly in the browser — with page navigation, zoom controls, text search, thumbnail sidebar, and fullscreen mode — without requiring Adobe Reader or any plugin. Use it to view PDFs on devices where no PDF software is installed, or to preview a PDF before downloading it.
While modern browsers include a built-in PDF viewer, it varies in features and is unavailable in certain embedded browser contexts (Electron apps, webviews, some corporate environments). This tool provides a consistent, feature-rich PDF reading experience on any device.
Features: - Page navigation: previous/next buttons, jump-to-page input, keyboard arrow navigation - Zoom: in/out buttons, fit-to-width, fit-to-page, custom percentage zoom - Text search: Ctrl+F triggers a search panel that highlights all matches across all pages - Thumbnail sidebar: shows page previews for quick navigation in long documents - Fullscreen: expand to full browser window for distraction-free reading - Text copy: select and copy text from the PDF (for text-based PDFs) - Rotation: rotate the view for landscape documents
Rendering: pages are rendered using PDF.js — the same engine used by Firefox's built-in PDF viewer, maintained by Mozilla. All common PDF features are supported.
Privacy: the PDF is loaded into your browser and rendered locally. Your document is never sent to any server.
Frequently Asked Questions
- Yes, for text-based PDFs. Click and drag to select text, then Ctrl+C to copy. This works for PDFs that contain actual text data. Scanned PDFs (image-only) do not support text selection — use the Extract Text from PDF tool with OCR to get copyable text.
- Once the page is loaded in your browser, the PDF.js viewer is available. If you've already uploaded a PDF, you can disconnect from the internet and continue viewing. The PDF file itself is held in browser memory and remains viewable until you refresh or close the tab.
- Press Ctrl+F (or Cmd+F on Mac) to open the search panel. Type your search term — all matching occurrences across all pages are highlighted. Use the navigation arrows to jump between matches.
- Garbled text in PDF rendering usually means the PDF was created with font information missing or using non-standard encoding. The font glyphs are present but the Unicode mapping is absent. This is a PDF creation defect — the file itself has incorrect font encoding that no viewer can fully correct.
