What is an online PDF viewer?

An online PDF viewer opens a PDF in a browser for on-screen reading without a desktop reader. This viewer provides previous and next page controls, zoom, fullscreen mode, touch navigation, and a download control.

The current viewer renders one page at a time on canvas and does not provide text search, annotations, printing controls, or a password-entry flow. Available behavior depends on the PDF structure, browser, and device.

Quick answers

Frequently asked questions

What can I do in the online PDF viewer?
You can open one PDF, move between pages, zoom from 10% to 800%, enter fullscreen where supported, swipe pages at fit width on touch devices, and download the unchanged selected file.
Does the PDF viewer work on mobile?
The viewer has a responsive mobile toolbar and supports horizontal page swipes at fit width. Zoomed pages retain normal panning behavior. Performance depends on PDF complexity and available device memory.
Can I search for text in this PDF viewer?
No. The current viewer renders pages on canvas and does not provide a text-search control or searchable text layer. Use PDF OCR when a scanned document needs searchable text.
Can I open a password-protected PDF?
The current page does not provide a password-entry flow, so a protected PDF may fail to open. If you are authorized, unlock it with the correct password before using the viewer.
Is the selected PDF uploaded to a server?
No application document-processing request is used. The selected file is read and rendered locally in your browser.
What is the PDF viewer file-size limit?
The file handler does not enforce a fixed cap. Practical capacity depends on file size, page count, PDF complexity, available browser memory, and device performance.
