How-to
How to delete pages from a PDF in your browser
A blank page, a duplicate scan, or a page you never meant to include is common after scanning, merging, or exporting from another app. This guide removes one or more pages from a PDF without installing Acrobat or any other desktop software, and without sending the file to a server. The PDF Organize tool runs the whole operation locally, using PDF.js to show thumbnails and pdf-lib to build the new file.
Step by step
- Open the PDF Organize tool and drop your PDF in. The tool reads the page count and renders a thumbnail for every page directly in your browser, so you can see exactly what you are about to edit before changing anything.
- Click the x icon on every page thumbnail you want to remove. The page dims and gets a red outline to mark it as deleted; click the same icon again, now showing an undo arrow, if you change your mind before exporting. A counter below the grid tracks how many pages are kept out of the total.
- Type an output file name if you want one other than the default, then click Export. The tool rebuilds the PDF from the pages you kept, in their current order, and offers it as a download named yourfile-organized.pdf. Nothing is uploaded at any point in the process.
What deleting a page actually removes
Marking a page as deleted does not hide it behind a flag inside the same file the way some editors leave stray objects behind. When you click Export, pdf-lib copies only the pages you kept into a new PDF document; the deleted pages and their content are not included in the output at all. The file you dropped in stays untouched on your device: the tool works from a copy of its bytes in memory, and only the exported result is written to disk when you download it.
Reorder and rotate pages in the same pass
The same grid that lets you delete pages also lets you move a page up or down and rotate it 90 degrees at a time, so a scan that came out of order or sideways can be fixed alongside the deletion instead of running three separate tools. If you need to split the surviving pages into several files, or combine the result with another document, the PDF split and PDF merge tools both accept the file this tool produces.
No upload: thumbnails and export both happen locally
Rendering thumbnails uses PDF.js, the same rendering engine Firefox uses to display PDFs in the address bar, running inside your browser tab. Building the final file uses pdf-lib, a JavaScript PDF library that also runs entirely client-side. At no point does the PDF leave your device: opening your browser's developer tools and watching the Network panel during the whole process shows no request carrying the file.

Frequently asked questions
Does deleting pages make the PDF smaller?
Usually yes, roughly in proportion to how much of the original content was on the removed pages. A PDF where most of the size comes from embedded photos shrinks a lot when a page full of images is removed; a PDF made mostly of text barely changes size regardless of how many pages you remove. If the result is still too large for your purpose, run it through the PDF compressor afterward.
Can I remove a page from a password-protected PDF?
Not directly: the tool needs to read the page content to build thumbnails and the new file, so an encrypted PDF has to be unlocked first. Use the PDF unlock tool with the password you already know, then reopen the result here to delete pages.
