What is an online PDF viewer?
An online PDF viewer opens a PDF in your web browser, so you can read it on any device without installing a PDF reader. PDFDaily's viewer draws each page on your device, shows thumbnails of every page and lets you zoom in on small print.
Is it safe to view a PDF online here?
Yes, viewing a PDF here is private: the file is read in your browser and never sent to a server, which also makes large documents open quickly. Close the tab and nothing is left behind.
Can I do more than read the PDF?
Yes, the viewer leads straight into the tools you need next. Select Edit PDF to change text or add notes, Sign PDF to add your signature, or Compress PDF to make the file smaller for email. To combine it with other documents, use Merge PDF.
