Thêm số trang vào PDF

A page-number stamper adds clean, consistent numbers to every page of a PDF, in the position, starting number and format you choose, all in your browser.

It runs locally in your browser with pdf-lib, so it is instant and your document never leaves your device.

Numbered pages make a document easier to navigate, cite and print: readers can refer to a page, a reviewer can point to one, and a printed stack stays in order. It is a small touch that makes reports, contracts and handouts look finished.

You control the position, a corner or the center, the starting number, and the format, either a plain number such as 3 or a number with the total such as 3 / 12, depending on the look you want.

Setting the start number is how you handle a cover or title page: begin numbering at a later page, or split the cover off, number the rest, and merge it back if you want the cover to carry no number.

Adding numbers is lossless. The text, fonts and images of each page are kept, and the number is drawn into a margin, so the document stays the same quality and remains searchable.
