Create Blank PDF

Generate an empty PDF at an exact page size

Sometimes you don't need to convert anything — you need a clean PDF that already has the right page dimensions before you ever put content on it. This tool builds that document for you: pick a size, an orientation, and a page count, and you get a blank.pdf with empty pages set to precise physical measurements. No source file required.

Where a blank PDF actually saves you time

• A tablet notebook. Generate 50 or 100 blank A4 portrait pages, drop the file into GoodNotes, Notability, or Samsung Notes, and you have a paginated handwriting notebook — without buying a template pack.
• A spacer or cover page for merging. When you assemble a report with the Merge PDFs tool, a single blank page makes a clean section divider or keeps a double-sided print landing on the correct side. Create one page here, then merge it in at the right position.
• A stamping base. The Sign PDF tool drops a PNG signature onto a page, and Edit PDF stamps transparent overlays (notes, highlights, redaction boxes). Both need a page to stamp onto — a correctly-sized blank gives you a predictable canvas.
• A print-shop placeholder. Need an A1 landscape sheet for a poster proof, or a Tabloid (11×17 in) page to mock up a spread? Generate the empty page at the exact trim size so the layout starts from the right dimensions.

The sizes, in real measurements

The ISO 216 "A" series halves on each step: A4 is 210 × 297 mm, A3 is twice A4 (297 × 420 mm), and the chain runs A0 (841 × 1189 mm) down to A6 (105 × 148 mm). Every A size shares the same √2 aspect ratio, which is why scaling between them never distorts a layout. The North American sizes don't follow that rule: Letter is 8.5 × 11 in, Legal is 8.5 × 14 in, and Tabloid is 11 × 17 in. Choosing landscape simply swaps width and height. Internally a PDF measures pages in points (1 pt = 1/72 in), so the file carries the size as exact geometry, not pixels — it prints at true dimensions regardless of screen DPI.

Practical tips

• Pick the size to match your printer or device, not your screen. If you'll print at home or office, Letter or A4 portrait is the safe default.
• Generating a few hundred pages produces a tiny file — empty pages carry almost no data, so a 500-page A4 blank is only a few kilobytes.
• The page count is capped at 500. If you need more, generate two files and combine them with the merge tool.

When to use a different tool instead

• You have images to turn into pages — use Images to PDF, which sizes each page to your photos or scans.
• You already have a PDF and need its pages at a different dimension — use Resize PDF, which scales existing content rather than creating empty pages.
• You want page numbers stamped on a document — that's Number Pages; this tool only makes the blank canvas.

This tool never adds text, lines, or grid backgrounds — every page comes out genuinely empty. If you want lined or graph paper, generate the blank here and draw the rules in Edit PDF.
