Marks to add:

Use both when a review packet needs navigation and a document-status stamp.

Pages to mark:

Examples: all, all except cover, odd, even, 2-end, 1-3, 5.

Number format:

Keep {n} in the format so every selected page receives a number.

Number style:

Choose the running label style used by {n} and {total}.

Start number:

Use a higher number when continuing a combined packet.

first label

Number position:

Choose the header or footer location for page numbers.

Watermark text:

Use concise text that should appear on every selected page.

Watermark position:

Choose where the single watermark should sit on each selected page.

Watermark size: {{ normalized.watermarkFontSize }} pt

Scale the watermark for the current document size.

Watermark rotation:

Use negative values for a rising left-to-right diagonal.

deg

Watermark opacity: {{ normalized.watermarkOpacityPercent }}%

Subtle watermarks usually sit between 12 and 28 percent opacity.

Number font size: {{ normalized.numberFontSize }} pt

Number color:

Choose a color that remains readable on the document background.

Number horizontal margin:

Distance from the page edge when using left or right positions.

Number vertical margin:

Distance from the top or bottom edge of the page.

Mirror facing pages:

Odd pages use the outside right and even pages use the outside left when left or right is selected.

Watermark font:

Helvetica Bold is the default for clear status stamps.

Watermark color:

Choose a color that stays visible at the selected opacity.

Watermark horizontal offset:

Nudge the single watermark without changing the base position.

Watermark vertical offset:

Nudge the single watermark away from important document content.

Tile watermark:

Use this when a single centered mark is too easy to crop out.

Tile spacing:

Larger values create a lighter repeated pattern.

Output filename:

Leave blank to append -marked to the source filename.

A PDF often travels farther than the folder, email, or case note that explained it. Review packets get printed, exhibits are split from filings, board papers are merged into agenda books, and training handouts are forwarded without the original message. A visible mark drawn onto the page solves a practical problem: the page itself carries the cue a reader needs.

Visible page numbers and watermarks solve different parts of that problem. A page number gives people a shared way to cite, sort, and reassemble a packet. A watermark gives the page a status such as DRAFT, CONFIDENTIAL, APPROVED, or REVIEW COPY. Neither mark changes the legal meaning of the document by itself, and a watermark is not encryption, redaction, or access control.

Common PDF page mark types and limits
Visible mark	Common job	Main limit
Page number	Citations, packet navigation, print sorting, and appendix numbering.	It may not match the page label shown by the PDF viewer.
Watermark	Draft status, confidentiality notice, approval state, or review copy warning.	It warns readers but does not secure, redact, or remove content.
Tiled watermark	Repeated status text across pages that might otherwise be cropped or copied.	It can make dense scans harder to read if opacity or spacing is too strong.

PDF numbering can be messy because several numbering systems can coexist. A viewer may show page labels, the original document may already have printed folios, and a visible packet sequence may start after a cover or continue from another volume. A cover sheet, appendix divider, exhibit slip, signature page, or replacement page can all justify a visible sequence that does not match the source file's page count.

PDF page with a selected range, footer page number, watermark, margins, and page box.

Placement is a page-geometry problem. Existing PDF content does not move aside when a footer number or watermark is added. A mark that is mathematically inside the page can still cover a signature block, collide with an old footer, sit too close to a binding edge, or disappear into a shaded scan. Page size, rotation, margins, text width, opacity, and mirrored outside numbering all affect whether the mark stays useful.

A marked copy should be treated as a review aid, not as the source of truth for security or document control. Page marks help readers talk about the same sheet of paper; they do not prove that every copy was updated, that hidden content was removed, or that the recipient has permission to see the file.

How to Use This Tool:

Use one source PDF per pass. The PDF is read in the browser, and the marked download is created there after the settings pass validation.

Choose, drop, or load the demo PDF. Source files must be PDFs, stay within the 75 MB file cap, and have no more than 500 pages for the browser-side marking pass.
Choose Marks to add. Use page numbers for navigation, a watermark for visible status text, or both when the packet needs a sequence and a review label.
Set Pages to mark. The range accepts practical phrases and tokens such as all, all except cover, odd, even, first, last, exact page numbers, closed ranges such as 2-8, open ranges such as 4-end or 8-, and exclusions with !.
If page numbers are enabled, set the format, style, starting number, and position. Keep {n} in the format. Add {total}, {page}, or {docTotal} only when the label needs selected-page total, original source page, or whole-document page count.
If a watermark is enabled, choose concise text, placement, size, rotation, opacity, color, and optional tiling. Lower opacity keeps body text easier to read; tiled mode repeats the mark and ignores the single-position setting.
Open Advanced when margins, colors, facing-page mirroring, watermark offsets, tile spacing, font choice, or the output filename need adjustment.
Click Mark PDF, then inspect Marked PDF, Mark Setup, and Page Placement. If the button is disabled, check for a missing file, blank watermark text, a number format without {n}, too many pages, or a range that selects no pages.

Interpreting Results:

Marked PDF confirms whether an output file exists, which source file was used, how many pages were marked, which mark mode ran, the output filename, file size, and local processing note. Mark Setup is the settings audit. Page Placement is the quickest place to catch wrong ranges, unexpected number text, mirrored positions, watermark stamp counts, and mixed page boxes before sharing the file.

PDF page marking result checks
Result cue	What to verify	Common misread
Pages marked	The listed pages match the intended source pages.	A selected-page total is not always the whole PDF total.
Number mark	The resolved text uses the intended format, start number, and style.	`{page}` is the original PDF page, while `{n}` is the running selected-page label.
Number position	Header or footer placement is correct after any facing-page mirroring.	Mirroring changes left/right anchors by page parity for outside numbering.
Watermark stamps	A single stamp or tiled repeat count appears as expected.	A tiled watermark can add many marks per page and may be too dense at small spacing.
Page box	Mixed sizes and rotated pages are reviewed in the downloaded PDF.	Point dimensions describe geometry, not whether the visible content leaves enough blank space.

Warnings should be treated as part of the result, not as background noise. Invalid range tokens may be ignored, ranges beyond the document can be clipped, rotated pages need manual inspection, and an empty selection means no output can be made. The downloaded PDF is the final evidence because it shows the marks as future readers will see them.

Technical Details:

Visible PDF marks are drawn into page content. A page number is text placed at a calculated header or footer coordinate. A watermark is text placed at a single anchor or repeated across a page grid. Existing text, scans, signatures, and images are not reflowed, rewritten into editable paragraphs, or moved away from the new mark.

PDF placement uses page boxes measured in points. In common PDF user space, 72 points represent one inch, so a letter-size page commonly appears as 612 by 792 points. The origin used for drawing text is at the lower-left of the page box. Header and footer placement therefore depends on page width, page height, margins, font size, and the measured width of the actual label text.

Rule Core:

PDF page marking rules and boundaries
Rule	Behavior	Boundary
Page range	Named pages, odd/even pages, exact numbers, and ranges are converted into a sorted one-based page list.	Invalid tokens are warned about; pages beyond the source length are ignored or clipped.
Exclusion	`all except ...` starts with the full document and removes named pages or ranges.	`cover` and `first` both refer to source page 1.
Number sequence	The first selected page receives the start number, and later selected pages increment by one.	The running label sequence is independent of the original PDF page number.
Number style	Arabic, padded Arabic, Roman numerals, and letter styles are generated from the running label number.	Padded numbers use the width needed by the largest selected running number.
Watermark tiling	Repeated anchor points are spaced by the selected tile gap across each selected page.	Each selected page is capped at 360 watermark stamps.

Formula Core:

The running page label is based on selected-page order, while placement is based on the page box and text metrics. These equations show the core coordinates before final clamping to the page bounds.

\begin{array}{lcl} n_{i} & = & s + i \\ x_{left} & = & m_{x} \\ x_{center} & = & \frac{W - T_{w}}{2} \\ x_{right} & = & W - m_{x} - T_{w} \\ y_{bottom} & = & m_{y} \\ y_{top} & = & H - m_{y} - f \end{array}

Here, s is the start number, i is the zero-based index within the selected pages, W and H are page width and height, T_w is measured text width, f is font size, and m_x and m_y are horizontal and vertical margins. Left placement uses the horizontal margin directly. Center and right placement change when the label text gets wider.

A simple substitution shows why a long label shifts right-aligned text. On a 612 pt wide page with a 36 pt horizontal margin and a 72 pt label width, the right x-coordinate is 612 - 36 - 72 = 504 pt. If the label widens to 100 pt, the same right edge stays inside the margin, but the starting x-coordinate moves to 476 pt.

PDF page mark validation bounds
Input	Accepted range or pattern	Effect on marks
Source PDF	PDF file, up to 75 MB and 500 pages for processing	Protects browser memory during local reading and writing.
Start number	1 to 999999	Sets the first running page-number label.
Number font size	8 to 24 pt	Changes label height and top-position offset.
Number margins	12 to 144 pt	Controls distance from page edges for header and footer numbers.
Watermark text	Up to 120 characters, required when watermarking	Blank text blocks watermark output.
Watermark opacity	5% to 100%	Balances visibility against interference with page content.
Watermark rotation	-90 to 90 degrees	Controls the stamp angle for single and tiled watermarks.
Tile spacing	120 to 480 pt	Controls the density of repeated watermark anchors.

Privacy Notes:

The selected PDF is read and rewritten in the browser, and the marking action does not make an upload request for the source file. The page may still need network access to load PDF-writing support before a marked PDF can be created. Treat the downloaded file as a new document copy and review it under the same confidentiality rules as the source.

Advanced Tips:

Use all except cover for review packets with a title sheet, then confirm the first marked source page in Page Placement.
Use {page} only when the visible label must show the original source page. Use {n} for a clean running sequence across selected pages.
Turn on facing-page mirroring when footer numbers should sit on the outside edge of a printed spread; inspect even and odd rows before sharing.
Keep watermark opacity low on scanned or text-heavy pages, and raise it only after the downloaded PDF remains readable at normal zoom.
Use tiled watermarking sparingly. Smaller tile spacing can add many stamps per page, and each page is capped at 360 stamps for browser memory safety.

Worked Examples:

Board review packet: A 24-page PDF has a cover plus 23 agenda pages. Use all except cover, page numbers at bottom right, and a low-opacity CONFIDENTIAL watermark. Page Placement should list 23 source pages, starting at source page 2.

Continued appendix: A report appendix begins on source page 8 and should continue a larger binder at number 101. Use 8-, set the start number to 101, and use a format such as A-{n}. The stamped number sequence follows selected pages, not the source page values.

Troubleshooting a blank range: A 12-page PDF with range 20-30 will produce a warning because no source pages match. Change the range to a valid span such as 2-12 or all except cover, then confirm the selected page count before marking again.

Tiled draft proof: A proof copy uses watermark-only mode, tiled watermark on, a diagonal rotation, and a wider tile gap. The placement rows show how many stamps each selected page receives, but the downloaded PDF still needs inspection because dense scans can make low-opacity text hard to read.

FAQ:

Does this change PDF page labels?

No. It draws visible text onto selected pages. Viewer page labels are a separate navigation feature and can differ from the numbers printed or stamped on the page.

Can a watermark protect a confidential PDF?

No. A watermark is a visible notice, not encryption, redaction, or access control. Use proper PDF security and redaction workflows when the file needs actual protection.

Why is the Mark PDF button disabled?

Common causes are no loaded PDF, more than 500 pages, no selected pages, a number format missing {n}, blank watermark text, or a mark mode with no visible mark to add.

What happens with rotated or mixed-size pages?

The placement table reports each page box, and rotated pages trigger a warning. Open the downloaded PDF before sharing because the coordinate box can be valid while the visual orientation still needs review.

Will existing text or images move away from the new marks?

No. Page numbers and watermarks are drawn at calculated coordinates. Existing text, images, scans, and signatures do not reflow around them.

Glossary:

Visible page number: Text drawn directly onto the page, usually in a header or footer position.
PDF page label: A navigation label shown by a PDF viewer. It may not be printed or visible on the page content.
PDF point: The coordinate unit used for placement. One inch is commonly represented as 72 points.
Selected-page total: The count of pages chosen by the range, which can differ from the total number of pages in the source PDF.
Facing-page mirror: A placement option that sends odd pages to the right side and even pages to the left side when outside numbering is needed.
Tiled watermark: A repeated grid of watermark text rather than one single watermark anchor.
