TSUBAMI / PRACTICAL GUIDE
Merge, split, extract or reorder PDF pages?
Choose the right page operation before processing your document.

Merge brings files together
Use Merge PDF when two or more documents should become one. The file list determines which document comes first. You can move files with the arrows, sort names alphabetically or reverse their order. Open the result and verify the transition between documents.
Extract makes one selected document
Extract PDF pages creates one new PDF from page numbers or ranges. For example, 4, 1-2 puts page four first and then pages one and two. Numbers refer to positions from the beginning of the file, rather than printed page labels.
Split creates several files
Choose Split PDF for one file per page, fixed groups of N pages or custom ranges separated by semicolons. For example, 1-2; 3-5 produces two files. Multiple outputs also have a ZIP download. Splitting does not automatically guarantee a particular file size.
Organize duplicates and reorders
Organize PDF accepts an explicit sequence with repeated page numbers. The sequence 3, 1-2, 3 produces four pages and includes page three twice. Omit pages you do not want, or use Remove PDF pages to name the pages that should be deleted instead.
Check more than appearance
Page operations copy or rewrite document structures. They do not intentionally rasterize the page, but interactive form behavior, bookmarks and annotations can change. Modifying a signed document can invalidate its digital signature. Keep the original signed file and inspect important outputs in a suitable reader.
Continue locally
After processing, Use result carries the generated copy to another compatible tool in tab memory. For example, merge first, then add page numbers. This is a local handoff; leaving, reloading or closing the page clears the in-tab files.
