Organise PDF pages visually

See every page as a thumbnail, then drag to reorder, rotate what is sideways and drop what you do not need. All of it in your browser, with nothing uploaded.

Thumbnails are rendered on this device.

    Nothing is uploaded. This page opens and rewrites your PDF using your own browser's memory, then shows you the finished pages so you can check them before you download.

    Using Organise PDF, step by step

    1. Drop a PDF onto the box above. Every page is rendered as a thumbnail so you can see what you are working with.
    2. Drag a page to move it, or use the arrows on the thumbnail. The number under each page shows where it will end up.
    3. Use the rotate button on any sideways page, and the cross to mark a page for deletion. Marked pages fade out and can be restored.
    4. Press Save organised PDF to build the new document and download it.

    The document nobody assembled on purpose

    Most PDFs that need organising were produced by a machine rather than a person. A sheet-fed scanner returns pages in whatever order they came off the stack, and inserts an occasional blank when it catches the back of a single-sided sheet. A phone camera records whichever way you were holding it. A merged pack inherits the ordering of a file browser rather than of a reader. None of this is anyone's fault, but the result is a document that works against the person reading it.

    Fixing it is worth more than it seems. If a document is going to a reviewer — an admissions officer, a loan officer, a procurement committee — they are working through a queue and forming an impression fast. Pages in the right order, the right way up, with the blank sheets gone, reads as competence. It costs two minutes.

    Working with the grid

    Everything here is reversible until you press save. Dragging a thumbnail picks it up and drops it between two others; the arrows do the same thing one position at a time, which is more precise for small adjustments and works with a keyboard. Rotation steps in ninety-degree increments and shows you the result immediately, so you can tell a page that needs 90° from one that needs 270° without guessing.

    Deletion is deliberately soft. A marked page fades and stays in place rather than vanishing, which means you can mark half a dozen candidates, look at the whole document, and change your mind about one of them before committing. Restore deleted brings everything back at once.

    Two bulk actions cover the most common mechanical problems. Rotate all 90° fixes a document scanned entirely in landscape. Reverse order fixes the classic sheet-feeder result where a stack has come out back to front — a job that is miserable one page at a time and instant in bulk.

    What gets written to the new file

    When you save, a fresh PDF is built by copying the page objects you kept, in the order you set, with the rotations you chose recorded as page properties. Nothing is redrawn, so text stays selectable and images keep their exact resolution. The file size will drop roughly in proportion to the pages you removed.

    If the finished document then needs page numbers, add them afterwards rather than before — numbering before reordering produces a document whose printed numbers disagree with its actual sequence, which is worse than having no numbers at all. Same logic applies to compression: shrink the final arrangement, not an intermediate one.

    Frequently asked questions

    Can I undo a deletion?

    Yes. Deleting only marks a page — it fades out and the button turns into a restore button. Nothing is actually removed until you press save, and even then your original file on disk is untouched.

    Does rotating here save the rotation permanently?

    Yes. The rotation is written into the page's own properties, so every reader and printer will show it the right way up. This is different from the temporary "rotate view" button in most PDF readers, which only changes what you see and is forgotten when you close the file.

    Why are the thumbnails a little slow on a long document?

    Because each one is genuinely rendered — your browser draws every page exactly as a reader would. For very long documents the tool renders the first pages first so you can start working while the rest catch up. It is still far quicker than uploading the file somewhere.

    Will reordering degrade quality?

    No. Pages are copied whole into a new document. The thumbnails are throwaway previews; the pages that get saved are the original page objects, untouched.

    Can I organise several PDFs at once?

    Combine them first with Merge PDF, then bring the merged file here. That way you see every page from every source in one grid and can interleave them freely.
