A PDF is a structured document, not a flat image. Splitting, merging, rotating or deleting pages rewrites that structure, and it can all run in your browser so the file is never uploaded.
01A safe order of operations
Inspect the document first: read its version, page count and metadata before changing anything.
Decide the page selection, then apply exactly one structural change at a time.
Download the result and reopen it to confirm the page count, order and orientation.
02Rewriting keeps the document valid
Every output is a new PDF with its own page tree, cross-reference table and trailer, so it opens in any reader. Unselected pages are copied unchanged.
Frequently asked questions
Are my PDFs uploaded?
No. The file is read and rewritten locally in your browser; nothing is sent to a server.
Which pages change?
Only the pages you name. Rotation, extraction and deletion leave every other page exactly as it was.
