Add page numbers to a PDF.

Five: 1, Page 1, Page 1 of 9, 1 / 9 and - 1 -. In the formats with a total, the total is the last number written, so it stays right when you skip pages or start from another number.

At the top or the bottom of the page, on the left, in the middle or on the right, at a margin from 8 to 96 points from the edges (72 points is an inch). A page turned in the file gets its number where the reader sees the top or bottom, standing upright.

Helvetica, one of the fonts built into every PDF reader, so nothing is embedded and the file barely grows. The size runs from 6 to 36 points, in any color.

No. Each number is drawn over the page's own content, so text stays selectable and nothing is redrawn. Links and form fields are kept.

No. The PDF is read into your browser's memory and numbered there with pdf-lib, an open-source library, and the page makes no request with it. Files up to 500 MB work, memory allowing.

Write 2- in Pages to number from page 2 to the end. Numbering counts the pages that get a number, so page 2 would show 1; set Start at to 2 and it shows 2.

Yes. Pages takes a list such as 1-3, 5, 8-, and the pages left out get no number; they're dimmed in the strip under the preview. Leave it empty to number every page.
