What is a PDF page organizer?
This tool lets you organize a PDF like a photo album: every page appears as a thumbnail, and you can delete the pages you don’t want and reorder them with arrows, then export a clean new PDF. It all runs locally in your browser — pdf.js for the preview, pdf-lib for the rebuild — with no upload.
How to use
- Select or drop in a PDF.
- Click "✕" on a thumbnail to delete a page, and "↑ / ↓" to reorder.
- Click Download to export the organized PDF.
Common use cases
- Remove blank or unwanted pages from a scan.
- Put pages back into the right order.
- Pull out inner pages you don’t want to share before sending. To merge several PDFs or split out a range, use the matching PDF tools.
Deleting one page removed 99%; deleting another removed <1%
Same five-page document, same tool, same “delete one page” action — and two completely different outcomes. Drop page 3 and 3.4 KB remains (-99%). Drop page 4 and 333.3 KB remains (-<1%). The difference is not in the tool but in what the page held: page 3 carries a photograph, page 4 only text. There is a loop here you can close with a calculator. Extracting page 3 gives 339,189 bytes; deleting page 3 leaves 3,513. Together that is 342,702 against an original of 342,093 — just 609 bytes more. That excess is each output carrying its own copy of the PDF file structure, and our merge page measures the same effect in reverse (859 bytes less). Two tools, two directions, numbers that agree. The practical upshot: to shrink a PDF, stop counting pages and find the heavy one.
