About PDF Reader
This PDF reader lets you open a PDF file when a computer has no PDF app, a work laptop blocks installs, or you'd rather not open an attachment in some unknown program. Choose a file and it opens in the browser straight away. Pages load as you scroll and give their memory back when they are far away, so even a long document stays quick on a phone, and the page you stopped at is remembered on this device for next time.
Search looks through every page, highlights each match and steps through them with a counter, and the text can be selected and copied like on a web page. The side panel shows page thumbnails and the PDF's own contents, and links inside the document work. Fit the width or the whole page, zoom, rotate, switch to night mode for reading in the dark, turn pages with the arrow keys, and print or download. A PDF with an opening password opens once you type it. Everything happens on your device: the PDF is never uploaded, so reading doesn't use any of your daily tasks.
