Add Blank Page to PDF

Why add a blank page?

A blank page is the quiet workhorse of PDF editing. Print shops often want a blank sheet before a cover so the first real page lands on the right side of a booklet. Double-sided documents sometimes need a spacer so each chapter starts on a fresh leaf. And when you plan to scan a signed sheet back in, an empty placeholder holds its spot until the real one arrives. This tool inserts one clean, empty page exactly where you point it — no shuffling, no re-exporting from the original app.

Matched to your page size

Nothing looks worse than a Letter-sized blank stuck between A4 pages. This tool reads the size of the neighbouring page and builds the new blank one to match, so it slots in seamlessly whether your document is Letter, A4, Legal, or a custom dimension. Everything happens in your browser using pdf-lib — your file is never uploaded to a server, so private contracts, medical forms, and financial statements stay on your device.

How to use it

1. Click PDF file and choose the document you want to edit.
2. Pick where the blank page goes: at the start, at the end, or after a specific page.
3. If you chose "after a specific page," type the page number to insert behind.
4. Click Add blank page & download and grab the new file from your downloads.

FAQ

Does the blank page match my document's size?

Yes. The new page copies the width and height of the page next to the insert point, so it fits your Letter, A4, or custom layout perfectly.

Is my file uploaded anywhere?

No. Everything runs locally in your browser. Your PDF never leaves your device, which keeps sensitive documents private.

Can I add more than one blank page?

Each run adds one blank page. To add several, just run the tool again on the file you downloaded, or repeat for each spot you need.

Will it work on a password-protected PDF?

Encrypted or password-protected PDFs can't be opened here. Remove the password first, then add your blank page.
