Notes
- Numbers are drawn on top of the page content. If a page already has a number, header or footer in that place, they will overlap: check the preview and change the position or margin.
- Positions follow the page as it is displayed, so rotated and landscape pages get upright numbers in the corner you chose.
- Numbers and text in Western European characters are added as real text with a standard PDF font. If the format contains other characters, such as Korean, Japanese, Chinese, Thai, Cyrillic or Vietnamese letters with tone marks, each number is added as an image drawn with your device's fonts and cannot be selected or searched.
- Digital signatures in the PDF become invalid, because the file is changed. Encrypted (password-protected) PDFs are not supported.
- The numbers are printed on the pages only. The page labels that some PDF readers show in their page box are not changed.
- Very large PDFs (over about 100 MB or several thousand pages) need a lot of memory and may fail on phones.
- The PDF is processed in your browser and is not uploaded to LeedyBox. PDF.js and pdf-lib are loaded from leedybox.com itself.
How to use
- Choose a PDF or drop it on the box. Encrypted PDFs cannot be used.
- Choose where the numbers go and the margin. Turn on "Mirror on facing pages" for double-sided printing.
- Pick a format such as "Page {n} of {total}" or type your own, and choose Arabic or Roman numerals and the start number.
- Choose the pages to number, for example skip a cover page, and decide whether the skipped pages count.
- Set the font, size and colour, check the preview and press "Add page numbers and download". Open the downloaded file to check it.
Frequently asked questions
Is my PDF uploaded to a server?
No. The PDF is read and changed in your browser with the pdf-lib library and is not uploaded to LeedyBox. Only the libraries themselves are downloaded, from leedybox.com itself.
How do I leave the cover page without a number?
Choose "Skip the first pages" and enter 1. If the cover should still count as page 1, so that the next page shows 2, turn on "Count the pages without a number". Otherwise the first numbered page gets the start number.
What happens if my PDF already has page numbers?
Existing numbers cannot be removed or detected by this tool. New numbers are drawn on top of the page, so choose a position and margin where the page is empty and check the preview.
Can I use words in my own language, such as Korean or Russian?
Yes. Type them in the text field around {n}. The standard PDF fonts only cover Western European characters, so in that case each number is drawn with your device's fonts at about 300 dpi and added as an image. It prints sharply but cannot be selected or searched.
Is there a limit on file size or number of pages?
There is no fixed limit, but the whole PDF is held in your device's memory. Files over about 100 MB or with thousands of pages may be slow or fail, especially on phones. Encrypted PDFs are not supported.
