PDF Toolbox
Merge, split, rotate, and remove PDF metadata.
How to use this tool
Steps
- Add one PDF to inspect its page count and metadata. Use the single-file controls for rotation, metadata cleanup, or splitting.
- For a split, enter ranges that account for every page exactly once. The tool rejects missing, duplicated, reversed, or out-of-range pages and packages valid parts in a ZIP archive.
- Add two or more PDFs to enter merge mode. Arrange the queue in the intended reading order before creating the combined file.
- Download the result, open it in a second PDF viewer, and only then clear the queue. The queue is stored in this browser's IndexedDB until it is cleared.
Supported formats
- Input: one or more PDF files that PDF.js and PDF-lib can open.
- Merge output: one PDF containing copied pages in queue order.
- Split output: a ZIP archive containing one PDF for each complete page range.
- Rotate or metadata output: one rebuilt PDF downloaded by the browser.
Things to know
- Password-protected or damaged PDFs may fail to open.
- Rotation applies 90 degrees clockwise to every page, not a hand-picked subset.
- Splitting requires all pages to be assigned; it is not a page-deletion shortcut.
- Rebuilding a signed PDF invalidates the original signature relationship, and interactive features should be retested.
