delete-pdf-pages

A delete-PDF-pages tool removes selected pages from a PDF and saves the result as a new file (the original on disk stays untouched). The ZTools Delete PDF Pages tool offers a thumbnail grid where you click to mark pages for deletion, plus a range-string input for power users (5, 8-10, 15). Built on pdf-lib, it preserves text quality, images, fonts, and form fields on the remaining pages exactly. Useful for trimming blank pages, removing confidential appendices, or excising scanned photos that snuck into a document scan.

Use cases​

Removing blank pages produced by a scanner​

Auto-feeders sometimes capture blank backsides of single-sided originals. Click the blank thumbnails, hit Delete, save the cleaner file.

Removing confidential pages before external sharing​

A board pack has internal salary data on pages 28-35. Delete those pages, save as the "external" version, send. Keep the original intact for board records.

Trimming a draft to its final length​

You drafted 30 pages but the final report should be 20. Delete the cut sections in one operation; faster than recreating the file.

Removing unwanted cover or appendix pages​

A downloaded PDF has marketing covers, table-of-contents, and bibliographies you don't need. Delete pages 1-3 and 45-50 to keep just the body.

How it works​

  1. Drag-drop your PDF — Loads into browser memory.
  2. Mark pages to delete — Click thumbnails to mark, or type a range string (5, 8-10, 15). Marked pages are visually crossed out.
  3. Preview the result — A "remaining pages" count shows how many will be in the output. Verify before saving.
  4. Click Delete and Save — pdf-lib builds a new PDF containing only the unmarked pages, preserving all original content.
  5. Download — Save the trimmed file. The original on your disk is untouched — this tool produces a new file.

Examples​

Input: 30-page PDF, delete pages 5, 12, and 28-30

Output: 26-page PDF with the remaining pages in original order

Input: 50-page scan with 10 blank backsides interspersed

Output: 40-page PDF, blanks removed, ready for archival

Frequently asked questions​

Will my PDF be uploaded?

No. Page deletion happens entirely in your browser via pdf-lib. No file leaves your device.

Is the original file modified?

No. The tool builds a new file from the source; your original on disk stays exactly as it was.

Are bookmarks preserved?

Yes for bookmarks pointing to surviving pages (re-indexed to new page numbers). Bookmarks targeting deleted pages are removed.

Can I undo a delete after saving?

No — the saved file omits the deleted pages. Always keep your original until you've verified the trimmed version is correct.

Can I delete pages from a password-protected PDF?

Unlock first with our PDF Unlock tool (you must know the password).

Is there a fast way to delete every blank page?

Manually clicking is fast for a few; for hundreds, use a desktop tool with auto blank-detection (e.g., qpdf or pdfcrop).

Tips​

  • Always preview "remaining pages" before saving — easy to delete more than intended.
  • Pair with our Rotate PDF tool when scanned pages need fixing AND trimming.
  • For frequent blank-removal at scale, a desktop tool with automatic detection is faster.
  • Keep the original file until the trimmed version is verified.
