Pages: merge/split

Reordering, merging and splitting pages

Manage PDF pages in blupdf: reorder and delete pages, merge several documents into one, split a document into parts, and understand page limits per plan.

Updated 2026-08-27 · 2 min read

The page panel on the left of the editor shows every page of the open document as a thumbnail. From there you can change the order, remove pages, bring pages in from other documents and split a document into several files — without leaving the editor or losing the edits you have made.

Reorder and delete pages

Drag a thumbnail up or down to move a page. Select several pages with Shift-click or ⌘/Ctrl-click and drag them together. To delete, select and press Delete or use the panel's trash button; deleted pages can be restored with Undo until you export.

Reordering and deleting within one document are free — they do not consume credits.

Merge documents

Choose Add pages in the page panel and pick another document from your dashboard, or upload a new file. Its pages are appended at the end (or after the selected page, if one is selected), and you can then drag them anywhere. The source document is left untouched.

Merged pages keep their own size and orientation, so a landscape appendix stays landscape. Text blocks on merged pages are editable like any others once the source has been parsed.

Split a document

Select the pages you want to extract and choose Split to new document. blupdf creates a new document containing those pages and, if you tick Remove from original, deletes them from the current one. Repeat to break a long file into chapters, or to send only the relevant pages of a report.

Page limits per plan

Each plan sets a maximum number of pages per document, checked at upload and after a merge:

PlanPages per documentFile size
Free1010 MB
Starter5050 MB
Pro200150 MB
Business1,000500 MB

If a merge would exceed the limit, blupdf tells you before anything changes. See pricing for plan details.

Credits

Moving pages between documents — merging in or splitting out — costs 10 credits per page moved. Reordering and deleting inside a document are free. Pages brought in from a document that was never parsed are parsed on arrival (50 credits per digital page, 80 per scanned page). Export is 20 credits per page of the exported document.
