How this service works

Documents: DOCX template fill, Office to PDF, any file to Markdown, PDF to Word, OCR, PDF pipeline.

Output

Returns a JSON object containing the numbered PDF either as inline base64 or a 24-hour download URL (with expiry, byte size, content type, and SHA-256 hash), plus metadata: operation name, input/output byte sizes, input/output page counts, first and last page numbers stamped, and a flag indicating whether untrusted active content (XFA, JavaScript) was stripped from the PDF.

Example use cases

Paginate client report before delivery

“Take this PDF at https://storage.example.com/q3-report.pdf and add page numbers at the bottom-right in times font size 10, formatted as 'Page {n} of {N}', and return a download link I can send to the client.”

Skip cover page in academic paper

“Add page numbers to my paper PDF at https://files.example.com/thesis.pdf, but start numbering from page 2 so the cover is skipped — use bottom-center placement, helvetica font size 10, and give me the file back as base64.”

Faint subtle page stamps for internal draft

“I need subtle page numbers on this draft PDF at https://docs.example.com/draft.pdf — use bottom-left position, courier font, size 8, opacity 0.3, black color, and return a download URL valid for 24 hours.”

When to prefer

Choose this endpoint when you need to add or customize page numbers on an existing PDF — especially when you need fine-grained control over font, color, position, opacity, format string (e.g. '2 / 10'), and page range (e.g. skipping a cover). It also sanitizes active content (JavaScript, XFA) from the PDF as a side benefit. Prefer it over general PDF editors when you want a lightweight, pay-per-call API that returns a clean numbered PDF without a full suite subscription.

Side effects

PDF URL is unreachable, private, or IP-literal — returns error refusing the URL
PDF exceeds 20 MB size limit
Invalid color hex pattern (must be #rrggbb)
Invalid pages range string format
font_size or margin out of allowed range
opacity below 0.05 or above 1
PDF is corrupt or not a valid PDF file
Network timeout fetching remote PDF

Input

Schema · Request body

Field	Type	Description
url	—	Public http(s) URL of the PDF (at most 20 MB; private, internal and IP-literal hosts are refused); or use pdf_base64.
font	string	Built-in PDF font: helvetica (default), helvetica-bold, times, times-bold, courier or courier-bold.
color	string	Text colour as #rrggbb (default #000000, black).
pages	—	Pages to number (default all), e.g. 2- to skip a cover.
format	string	{n} = this page's number, {N} = the last number.
margin	number	Points (1/72 in) from the page edge (0-144, default 28).
output	string	base64 (default): the file comes back inline as base64. url: the file is stored for 24 hours and the reply carries a download link (url, expires_at, bytes, content_type, sha256) instead of the base64, which keeps the file out of your context window.
opacity	number	0.05 (faint) to 1 (opaque, default).
position	string	top-left, top-center, top-right, bottom-left, bottom-center (default) or bottom-right.
font_size	number	Points (4-72, default 10).
pdf_base64	—	The PDF as base64 (at most 10 MB decoded per request); or use url.
start_number	integer	Number printed on the first numbered page.
