PDF Merge & Split

Read full description

Organize the pages of a PDF into the order you actually want. Merge, split, reorder, rotate, crop and extract — all in one screen, by dragging thumbnails. Organizing pages is free, at any length. Only exporting the result needs Pro — so you can get the document exactly right, see that it is right, and only then decide. ■ Page-level editing you can see · A thumbnail grid shows the whole document at once; drag to reorder · Select several pages to rotate, delete or crop them in one undoable step · Every page is labelled with the file it came from, so merges never get confusing · The thumbnail is the export — what you see is what you get ■ Merge and split · Combine several PDFs into one, in any order · Split by page, every N pages, or before pages you choose · See exactly how many files you will get, and which pages are in each, before committing ■ Extract and export · Select pages and export them as a new PDF · Every export is verified before it is called a success: the file is reopened and checked page by page · No watermark.

This is not redaction — the hidden content is still in the file and some PDF tools can recover it. To remove sensitive information permanently, use a tool built for redaction. The app says so in the crop editor, in Help, and in the Disclaimer. ■ Free includes · Unlimited editing: merge, reorder, rotate, delete, crop, duplicate and batch actions, at any length · Full preview, page-by-page browsing and undo · One watermark-free export: one source PDF, up to 10 pages · Your active workspace is always recoverable, even after an interruption ■ Pro unlocks · Export documents of any length · Export a document merged from any number of PDFs · Split and extract into separate files · Unlimited exports Pro is available as a one-time purchase or a yearly plan.
