Delete pages from a PDF

How Delete PDF Pages works

The file is read with a FileReader, rewritten in memory and offered as a download. This is why large PDFs are limited by your device's RAM rather than by an upload size limit. A 200 MB scan never crosses the network, so the slowest part is your own disk.

That is the whole architecture: static files, one script, no upload endpoint to leak or log. Close the tab and the work is gone.

Why deleting a page is not editing the original

A PDF stores pages as separate objects with a cross-reference table pointing at each one. Removing a page means building a new document that references only the pages you keep, then writing a fresh cross-reference table. The file you upload is opened read-only, so there is no way for this tool to damage it.

That is also why the output is usually a little smaller but never a lot: the pages you kept are copied with their own resources, fonts and images, and shared objects stay shared.

Marking pages quickly

Two ways to mark, and they combine. Click any number to toggle that single page, or type a list into the box — 1, 4-6, 9 — and press mark. A 200-page scan with three blank sheets at the end takes two seconds.

The counter under the grid always says how many pages will remain, which is the number that actually matters before you download.

What changes on the kept pages

Text, images, form fields and links stay exactly as they were. What can change: bookmarks that pointed at a deleted page lose their target, page labels renumber, and a link elsewhere in the document that jumped to page 7 may now land on whatever moved into that position. If the document has a table of contents, check it after the edit.

Encrypted PDFs are refused rather than silently mangled — remove the password in your reader first, then delete the pages here.

• No file size limit beyond your device's own memory.
• Free to use, with no account and no usage counter.
• Results are produced locally, so they are not logged or shared with anyone.
