Can I preview pages before deleting them?

Yes. Thumbnail previews of all pages are shown before you confirm any changes. You can see exactly which pages are marked for deletion and remove any mistaken selections before proceeding.

What happens to bookmarks that point to deleted pages?

Bookmarks (the PDF outline/navigation panel entries) that reference deleted pages are removed automatically from the output. Bookmarks that point to remaining pages are updated with corrected page number references if the deletion changed their numbering.

Is there an undo if I delete the wrong pages?

Before you download, you can reset your selection and start over. Once you have downloaded the file, re-upload your original and make the correct selection. It is good practice to keep a backup of the original PDF before making permanent deletions.

Can I delete pages from a password-protected PDF?

Yes, if you have the password. Enter it in the password field during upload. The output file will not be encrypted — if you need the output to remain password-protected, run it through the Encrypt PDF tool after deletion.

Does deleting pages reduce the file size proportionally?

Roughly, yes. If you delete half the pages, the file size will decrease by approximately half. The exact reduction depends on the content of the deleted pages — pages with large images reduce the file size more significantly than pages with only text.

What is the difference between Delete Pages and Extract Pages?

Delete Pages removes selected pages and gives you the remainder. Extract Pages saves the selected pages as a new separate PDF file, leaving the original unchanged. Use Delete Pages when you want to trim a document. Use Extract Pages when you want to create a subset document from specific pages.

Can I delete all pages except one specific page?

Yes. Select all pages using the 'Select all' control, then deselect the page you want to keep. Or use the range field to specify all pages except the one you need.

Does the tool detect and remove blank pages automatically?

Yes. The 'Remove blank pages' option scans for pages that contain no content or only white space and marks them for deletion automatically. You can review the detected blank pages in the thumbnail view before confirming.

I need to split a PDF into separate files, not just remove pages. Is there a tool for that?

Yes. The Split PDF tool divides a document into multiple separate PDF files based on page ranges or a fixed number of pages per file. This is more efficient than running Delete Pages multiple times to isolate individual sections.

Will the page numbers printed in the document content change after deletion?

No. If the PDF has page numbers printed as text within the page content itself — for example, '12' in the footer of page 12 — those are part of the page content and are not automatically updated. Only the logical PDF page references (bookmarks, internal links) are updated. If printed page numbers are important, you may need to use a PDF editor to update them manually after deletion.

How to Use

1Upload your PDF by dragging it into the upload area or clicking to browse for the file.
2Review the page thumbnails. Click any page you want to delete to mark it for removal, or type page numbers and ranges in the selection field.
3Verify your selection — marked pages are highlighted in the thumbnail view. Deselect any pages marked incorrectly.
4Click 'Delete selected pages' and wait for the tool to process the document.
5Download the trimmed PDF. Use Reorder Pages or Compress PDF as next steps if needed.

Printers, scanners, and PDF export tools have a habit of inserting pages you did not want. A scanner adds blank reverse sides from single-sided originals. A PDF export from a presentation includes a title slide you need to remove before sharing. A contract comes in with three pages of standard boilerplate that are not relevant to the signed version. Before you can use the PDF, you need to trim it — and doing that without a proper tool means either downloading desktop software or working around it by printing to PDF, which re-renders the content and often degrades image quality. Dokk.ai's page deletion tool shows you a thumbnail preview of every page in your PDF before you make any changes. Click a thumbnail to mark a page for deletion — marked pages are highlighted so you can review exactly what will be removed before committing. You can also type page ranges directly (for example, '1, 3, 7-10') to select a batch of pages at once without clicking each one individually. This is significantly faster for documents where you know the page numbers to remove but do not want to scroll through thumbnails. The deletion is processed on the server side, producing a clean PDF that contains only the pages you kept. Unlike printing to PDF, the remaining pages are not re-rendered — their original content streams, fonts, images, and vector graphics are preserved exactly. If the original PDF was text-searchable, the output is also searchable. If it had embedded bookmarks referencing pages that were deleted, those bookmarks are removed automatically to prevent broken navigation. For the complementary operation — taking a subset of pages out of a PDF to create a separate document rather than discarding them — the Extract Pages tool saves the selected pages as a new file while leaving the original intact. When the goal is to divide one long PDF into several smaller files based on page groups, the Split PDF tool handles this efficiently in a single step. If you are working on a larger reorganization of a PDF, deleting unwanted pages first, then using Reorder Pages to rearrange the remaining ones, and finally running Compress PDF to reduce the overall file size is a clean three-step workflow that produces a properly structured final document.
