Choose a fileThis online PDF reader opens any PDF file using PDF.js, entirely in your browser. No plugin, no download, no account needed. Navigate pages with keyboard shortcuts, zoom from 50% to 200%, and read your document without sending the file to any server. It works on Chromebooks, school computers, and any device where installing software is restricted.
Drop your PDF into the upload area or click to select it from your device. The reader loads the first page immediately. Use the navigation buttons in the toolbar or your keyboard arrows to move through the document. Pick a zoom level from the toolbar dropdown: 50%, 75%, 100%, 125%, 150%, or 200%. The print button in the toolbar sends the current page to your printer. There is no login prompt, no file size warning, and no waiting for an upload to complete.
After dropping the file, the dropzone is hidden and the reader takes its place. Click the upload area again if you need to open a different file.
The reader supports keyboard navigation so you can read hands-free. Press the right arrow or down arrow key to advance to the next page. Press the left arrow or up arrow key to go back to the previous page. These shortcuts activate as soon as a PDF is loaded. Zoom level must be changed using the toolbar dropdown. Keyboard navigation does not conflict with scrolling inside a page at 100% zoom.
Opening a PDF locally requires software: Adobe Acrobat Reader on Windows, Preview on macOS, or a third-party app on mobile. On Chromebooks, dedicated PDF software does not exist at the OS level beyond the built-in viewer. On school or work computers, IT policy often blocks software installation. This online reader requires nothing beyond a browser tab. It opens standard PDFs, scanned documents, and most files that don't require a password, without any installation step.
The main difference from a desktop reader is that this tool is read-only. It has no annotation or editing functions. If you need those, other tools on this site handle them separately.
Most online PDF readers upload your file to a server before displaying it. Google Docs, for example, sends the file to Google's servers when you open a PDF through it. That means a third party processes and may temporarily store your document. This reader uses PDF.js to render the document entirely inside your browser tab. The file is read from your device's memory and never transmitted over a network.
This matters when the PDF contains medical records, legal documents, financial statements, or any content you'd prefer not to pass through external infrastructure. The file stays on your device from the moment you drop it to the moment you close the tab.
This reader is designed for reading only. It does not support annotation, text highlighting, form filling, or editing. If you need to add text to a PDF, use the Add Text to PDF tool. For form filling, signing, merging, splitting, or compressing, see the full list of 49 PDF tools on the home page. The reader also cannot open password-protected PDFs that require a password to view. Use the Unlock PDF tool first to remove the password, then open the file here.
Very large PDFs with many high-resolution pages may take a few seconds to render per page. This is a browser memory limit, not a server limit, since all rendering happens locally.
