PDF page organizer

How to use it

1. Drop one PDF on the card, paste with ⌘V / Ctrl+V, or press “Choose PDF”. Every page appears as a card in output order; thumbnails render as you scroll.
2. Drag a thumbnail to move a page, or use the six buttons on each card: rotate left / right 90°, move earlier / later, duplicate, and remove. The buttons work with touch and keyboard.
3. The new PDF rebuilds automatically after every change — there is no Apply button. When the result bar turns green, preview it or download the new PDF. Undo and Reset are always available.

Example

Move p.5 to the front
Rotate p.2 right 90°
Delete p.6

report-organized.pdf — 5 pages
Order: p.5, p.1, p.2 (90°), p.3, p.4

The output name comes from the source file and is never translated. Rotation is written as page metadata on top of the page’s own rotation; the page content is not re-rasterised.

Rules, limits and known issues

• Nothing is uploaded: the PDF is read with the File API and rebuilt in this tab. The page sends no network request, writes nothing to storage, and keeps no history — a reload starts empty.
• Page content is copied, not re-encoded or compressed. Images and fonts keep their original compression, so the output is usually close to the source size; duplicated pages can make it noticeably larger. This is not a compression tool.
• Rotation is page metadata (`/Rotate`), not a new bitmap. Readers show and print the rotated page, but downstream tools may interpret the metadata differently.
• Password-protected PDFs are rejected; there is no password prompt or “ignore encryption” option. Remove the password first and save an unprotected copy.
• Form fields are not carried over. The output is not a fillable form; flatten the form in the source if it must look exactly as it does now.
• Bookmarks/outlines, attachments and document metadata (title, author, subject) are not copied. The output gets a localised title and a YKit Creator/Producer tag. Links on the page usually survive, but links to named destinations or bookmarks may stop working.
• Any organization changes the bytes, so digital signatures are no longer valid. PDF/A, PDF/X and other conformance markers are not preserved either.
• Duplicated pages repeat the full page content. A page may appear several times, increasing both the page count and the output size.
• Limits: one PDF, 50 MB, 500 source pages and 1,000 output pages. Over-limit files are rejected; duplicating is disabled at 1,000 pages. Undo keeps up to 30 steps in memory, and at most 2 thumbnails render at once.
• Thumbnails render on demand as pages approach the viewport. Complex pages can be slow or fail to render; a failed thumbnail does not block moving, rotating, duplicating, removing or exporting the page. Thumbnails use the browser’s built-in fonts and no remote font or character-map files, so a few pages (typically some CJK documents) can show missing glyphs in the preview only — the exported PDF is never affected.
• Result preview uses your browser’s built-in PDF viewer. Inline display and mobile behaviour depend on the browser; if the preview area stays blank, open the result in a new tab or download it.
• Undo exists only in this session and holds up to 30 steps. Reloading, replacing the source file or clearing the tool discards the history — nothing is written to storage.
• Output names replace path separators, control characters and reserved characters with “-”, trim the ends, cut long names and add “-organized.pdf”. The source file itself is never modified.
• All processing runs on the main thread. Large files can occupy the tab for several seconds and make other interactions feel slow; the status shows building progress while it works.
• The sample PDF is generated locally for demonstration only. It is not a real document and contains no personal data.
