Press the button and save the result. Several files come back as one ZIP archive.

The number is written into the page, not painted over it

Each number is appended to the content stream of its page, the same way the original text was written there. Nothing is re-rendered and nothing is flattened into a picture: images keep their original compression, text stays selectable, links, bookmarks and form fields keep working, and the file grows by roughly a kilobyte per page. Because the number is real text rather than a stamp, a reader can search for it, a screen reader can announce it, and a printer renders it crisply at any paper size.

Title pages, offsets and rotated sheets

Two separate settings cover almost every numbering habit. The first numbered page decides where printing starts, so a cover sheet stays clean. The starting value decides what is printed there, so a chapter can continue at 47 instead of restarting. A page range narrows the job further when only part of the document needs numbers. Sheets carrying a rotation flag are measured in the orientation you see on screen, and a crop box smaller than the paper pulls the margin inward, so the number never lands outside the visible area.

Your file stays on your device

The PDF is read, numbered and rewritten inside your browser tab. There is no upload, no queue on a server, and no copy left behind for anyone to delete later. Close the tab and the document is gone from memory, which is why confidential contracts and medical reports can be numbered here safely.

Frequently asked questions

How do I skip the title page?

Set the first numbered page to 2. Page one is then left untouched, and numbering begins on the second sheet. If you also want that sheet to read 1 rather than 2, leave the starting value at 1.

Can I start numbering at something other than one?

Yes. The starting value is what gets printed on the first numbered page, and it can be any number up to 99999. Continuing a bound report at 47 or matching a printed original is a common reason to change it.

What formats are there besides plain digits?

Six more: Page 3, 3 of 40, Page 3 of 40, lowercase and uppercase Roman numerals, and letters that run a, b, c and then aa, ab. A custom pattern also accepts the tokens for number, total and file name.

Does it work with Cyrillic and Chinese characters?

Cyrillic, Greek and Western European letters, yes. The three built-in PDF fonts only cover Western European letters, so as soon as your pattern contains anything else, a Noto Sans subset is embedded, which adds 40 to 120 KB once per document, not per page. Chinese, Japanese, Korean and Arabic words in a pattern are not supported yet, because that font has no glyphs for them: on those pages keep the pattern to digits, which print in every style.

What happens if the number lands on my text?

The number is drawn on top, so the two would overlap visually. Increasing the margin or moving to another of the nine positions fixes it in one step, and the bottom centre position is clear on almost every layout.

Can I remove the numbers later?

Not selectively, because they become ordinary page content once saved. Keep the original file if you may need a clean copy. Running the tool twice stacks a second number on top of the first rather than replacing it.

Is my file uploaded anywhere?

No. Everything runs in JavaScript inside your browser tab, and the file never leaves your device. There is no account, no queue and no server-side copy, so even a two gigabyte document is handled locally.

How many files can I number at once?

Up to twenty. The same position, format and font are applied to every one of them, each file keeps its own page count, and the results come back as a single archive named pulsarkit-numbered.zip.
