How to organize a PDF
- Drop a PDF onto the box or press Choose files. Every page appears as a numbered thumbnail; the numbers are the pages' positions in the original file.
- Reorder pages by dragging a thumbnail onto another, or with the ← and → buttons, which also work from the keyboard.
- Use ⟲ and ⟳ to rotate a page by 90°. The thumbnail turns so you can see the result before saving. Rotate all turns every page at once — useful when a whole scan came out sideways.
- Press ✕ to drop a page. It stays visible, greyed out, so you can bring it back with ↺.
- Press Save new PDF. A new file ending in -organized.pdf downloads; the file you opened is not modified.
The summary line tells you how many pages will be kept, how many are rotated and whether the order differs from the original, so you can check before saving.
How rotation and reordering work
Reordering and deleting are the same operation underneath: the tool builds a new PDF and copies in the pages you kept, in the order they are shown. Pages are copied as objects, not redrawn, so text stays selectable and images keep their quality.
Rotation is a setting, not a redraw
A PDF page has a /Rotate entry that tells viewers to display it turned by 0, 90, 180 or 270 degrees clockwise. Rotating here changes that entry only; the drawing instructions are untouched, so rotating is lossless and instant, and rotating four times brings a page back exactly to where it started.
Some pages already carry a rotation — scanners often record a sideways page this way. The tool adds your rotation to the existing one and wraps the result round to the range 0–270°. A page stored at 90° that you turn another 90° ends up at 180°; turn it 270° instead and it ends up at 0°.
Thumbnails
Thumbnails are drawn with pdf.js one page at a time, so a long document shows its grid immediately and fills in the pictures over a few seconds. You can start rearranging before every thumbnail has appeared.
Examples
| Starting point | Changes | Result |
|---|---|---|
| 3-page file (pages A1, A2, A3) | delete page 2, move page 3 first, rotate page 3 by 90° | 2 pages: A3 (rotated 90°), then A1 |
| 1 page already stored at 90° | rotate 90° clockwise | page stored at 180° |
| 1 page already stored at 90° | rotate 90° anticlockwise (the same as 270° clockwise) | page stored at 0° |
| 10-page scan, every page sideways | Rotate all ⟳ | all 10 pages upright |
A double-sided scan fed through a single-sided scanner often comes out as all the front sides followed by all the back sides in reverse. Here you can drag the pages into reading order and drop the blank backs in one pass, then save.
Limits
- Only 90° steps. Straightening a slightly crooked scan (deskewing) needs the page to be redrawn, which this tool does not do.
- Password-protected files must have their password removed in a PDF reader first.
- Bookmarks, form fields and attachments are not carried into the new file, because they belong to the original document as a whole.
- Very long documents — several hundred pages — take a while to draw thumbnails for and use more memory; the page still works while they load.
Frequently asked questions
Does rotating a page reduce its quality?
No. Rotation only changes the page's /Rotate setting; the content is not redrawn or re-compressed.
Is the original file changed?
No. Your browser cannot modify the file you opened. The tool creates a new file, name-organized.pdf, which you download.
Can I undo a deletion?
Yes. Deleted pages stay on screen, greyed out, until you save. Press ↺ to keep one again, or Undo all changes to start over.
Is my PDF uploaded?
No. Thumbnails are drawn and the new PDF is assembled entirely in your browser.
Can I combine pages from several PDFs?
Use Merge PDF to combine the files first, then open the merged file here to arrange the pages.
