Merge, split, rotate and reorder PDF pages
How to merge several PDFs, keep only the pages you need, and fix page orientation and order right in your browser, with nothing to install.
PDF is designed to preserve content exactly as it is, so editing the body text is hard, but page-level work is fairly easy. You will often need it when one page of a scanned contract is lying on its side, or when several documents have to be submitted as a single file.
How to do it with DocDori
- In the Workspace, open the PDF with ‘Open file’. The file is never uploaded to a server; it is processed only inside this browser.
- Rotate: go to the page you want to turn and press the rotate button. Each press turns it 90°.
- Reorder: use ‘Move earlier’ to move the current page one position forward.
- Delete and split pages: remove pages you don’t need with ‘Delete page’, and use ‘Export current page only’ to save a single page on its own.
- Merge: use ‘Merge PDFs’ to pick another PDF and append it to the end. The source files can total up to 50 MB, and the result can be up to 500 pages.
- Press ‘Download edited copy’ to download a new PDF file while the original stays untouched.
What it can’t do
- It does not edit PDF body text directly the way Word does, extract text from scanned images (OCR), or verify digital signatures.
- Covering content with a black box is not safe redaction. If you need to remove sensitive information, use a dedicated tool.
- Password-protected or signed PDFs are not opened or modified.
Common problems
The merged file is too big. Scanned PDFs are large because each page is a big image. Delete the pages you don’t need before merging and the file will shrink.
What about fillable form PDFs? Basic form fields such as text boxes, checkboxes and single-choice lists can be filled in and saved. In that case the page tools are disabled so the form doesn’t break.
When this comes in handy
- When you need to bundle several certificates into one PDF, for example for job application paperwork
- When pages got shuffled during scanning, or one page went in upside down
- When you want to send just the few pages of a long report that matter for a meeting
Frequently asked questions
What happens if I close the tab while working? Your edits are not saved anywhere. Once you have finished arranging the pages, download them with ‘Download edited copy’ before closing the tab.
Does the original PDF change? No. The original file stays as it is, and your changes are always downloaded as a new PDF. If you don’t like the result, just reopen the original and start over.
Does it work with PDFs that have many pages? A single document can be up to 25 MB, and a merged result can be up to 500 pages. If yours is bigger, first split it down to the pages you need and work on those.
