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.
