About the PDF Viewer

PDF Viewer opens one PDF from your device and displays it with a local copy of PDF.js — the file is never uploaded, changed or saved. Move between pages with the arrows, by typing a page number or by clicking a thumbnail, and use zoom in and out, fit width, fit page and rotate view. Fullscreen is available where your browser allows it. The viewer shows the file name, file size, number of pages, the current page and the zoom level, and Download Original saves the exact file you opened.

Search finds words in the text the PDF already contains and highlights the matches page by page. Scanned or image-only PDFs usually have no text layer, so there may be nothing to search — this viewer does not perform OCR. Password-protected PDFs can be opened if you know the password, and wrong passwords or damaged files are reported clearly. Very complex PDFs, forms and some fonts may look slightly different from other viewers.

Frequently asked questions

Is my PDF uploaded or changed?

No. It is opened only in your browser with a local copy of PDF.js. The viewer never modifies the file, and Download Original gives you back the exact same file.

Why can’t I search my scanned PDF?

Scanned or image-only PDFs usually contain pictures of text rather than real text. This viewer searches only existing text and does not perform OCR.

Can I open password-protected PDFs?

Yes, if you know the password. It is used only in your browser, and wrong passwords are reported clearly.

Does rotate change my file?

No. Rotate only changes how the page is shown in the viewer.

Why is there no fullscreen button?

Fullscreen depends on your browser. If it is not supported, for example inside some embedded browsers, the button is hidden.

Why does a page look different from another reader?

PDF readers render some complex graphics, forms and fonts differently. If something looks wrong, compare with another viewer.

Is my PDF uploaded anywhere?

No. The PDF is opened and processed by local copies of PDF.js and pdf-lib running in your browser. Nothing is sent to a server, and passwords you type are used only in this tab.
