Online PDF Viewer

What does the Online PDF Viewer do?

The Online PDF Viewer opens local PDF files directly in your browser and displays available document information. After you choose a file, it creates a local preview URL and reads metadata such as page count, title, author, subject, creator, and modification time. It is useful for quick reading, review, and printing.

Main features

Drag-and-drop upload: Click the upload area or drag in a PDF file.
Local preview: Uses the browser's built-in PDF viewer and does not intentionally upload the file to the application server.
Page navigation: Enter a page number to jump to a target page.
Fit modes: Choose automatic zoom, fit to width, or fit to page.
Document information: Read the file size, page count, and available PDF metadata.
Common actions: Open in a new tab, print through the browser, or download the original PDF.

How to use it

Select a PDF in the upload area or drag the file onto the page.
Wait for the tool to read the page count and document information, then use the preview panel to read it.
Adjust the page number and fit mode as needed.
Use Open in New Tab for a separate reading view, Print for a paper copy, or Download PDF to save the original file.

Privacy and compatibility

The PDF remains in the current browser session and is previewed through a local object URL. You need to select the file again after refreshing or closing the page. Built-in PDF capabilities vary by browser; if the embedded preview does not appear, open the file in a new tab. Password-protected, malformed, or very large PDFs may fail metadata parsing even when the browser can still display them.

FAQ

Why do page navigation or zoom behave differently across browsers? These parameters are handled by the browser's built-in PDF viewer, and support for URL options varies.

Does the tool modify the PDF? No. Reading, printing, and downloading all use the original file selected by the user. The tool only reads available document information.
