Organize PDF: how it works
To organize a PDF, open the Organize PDF tool and use drag-and-drop to reorder, rotate, or delete pages, then download the rearranged file. All edits happen in your browser, so the document is never uploaded.

- Drag page thumbnails to reorder them, rotate any page, or delete pages.
- Click to apply.
- Download the reorganized PDF.
In your browser vs. uploading to a server
Best for reordering scanned documents or assembling a report. Combines reorder, rotate, and delete in one private, in-browser view.
Frequently asked questions
How do I rearrange pages in a PDF?
- Open the Organize tool and drag the page thumbnails into the order you want; you can also rotate or delete pages in the same view before downloading.
Are my files uploaded to a server?
- No. PDFER runs entirely in your browser using WebAssembly and JavaScript. Your files are read into memory on your device, processed locally, and never sent to PDFER or any third party. Closing the tab or leaving the tool erases them from memory.
Is it free, and is there a file-size limit?
- Yes, it is free with no account, no watermarks, and no daily caps. Because processing happens on your own device, the only practical size limit is your device's available memory rather than a server upload quota.
