Delete PDF Pages

How do I delete pages from a PDF?

1. Drop a PDF onto the drop zone, or click it to choose one.
2. Wait for the thumbnail preview to appear, then click each page you want to remove; selected pages are highlighted.
3. Or type the page numbers into Pages to delete, for example 2, 5-7.
4. Click Delete pages.
5. Download the new PDF and check that the right pages are gone.

Delete PDF Pages renders a small thumbnail of every page with PDF.js so you can see what you are removing, then uses pdf-lib to build a new document containing only the pages you kept. The kept pages are copied as objects, not re-rendered, so text remains selectable, images keep their resolution and the file shrinks roughly in proportion to the pages removed. Deleting the 30 pages of appendices from a 40-page report cuts the size by about three quarters.

There are two ways to choose pages and they stay in sync. Clicking thumbnails is quickest when you can recognise the pages by sight, such as blank scanner pages, a cover sheet or a duplicate. Typing into Pages to delete is quicker for long documents: 2, 5-7 removes page 2 and pages 5 to 7, and ranges can be combined freely. Page numbers count from 1 and match the numbers under the thumbnails, which may not match numbers printed on the pages themselves if the document has a cover or preface.

The tool works on one PDF at a time so that the preview is unambiguous. You cannot delete every page; at least one must remain. If you want to keep only a small selection from a long file, it is often quicker to use Split PDF with a custom range such as 3-5 than to click through dozens of thumbnails. Password-protected PDFs need Unlock PDF first, and Reorder PDF Pages can also drop pages by leaving them out of the new order.

There is no file size limit beyond your device's memory, no signup and no watermark. Rendering thumbnails for a 500-page document takes a few seconds; the deletion itself is almost instant. Everything runs in your browser, the PDF is never uploaded and nothing is stored, so it is safe to use on contracts, statements and other private documents.

How it works: this tool uses pdf-lib and PDF.js (Mozilla), open-source libraries loaded into your browser. No server is involved, so Kilnfile never sees your file. Last reviewed 20 September 2026.
