Every long PDF collects pages that do not belong: the blank page a scanner added, the cover sheet a fax service prepended, the duplicate a merge created, the appendix nobody needs in this copy. This tool removes exactly the pages you mark — by typing ranges, by clicking thumbnails, or both — and saves the document without them, on your device.
Two ways to mark, one clear result
Ranges are the fast route when you know the numbers: “2, 4-6” marks page 2 and pages 4, 5 and 6, and the Mark button lights them up in the thumbnail grid so you can see precisely what will go. Thumbnails are the safe route when you do not: click a page to mark it, click again to unmark, and the marked pages turn red with their fate written on them. The stats panel keeps a running count — pages in the file, pages marked, pages remaining — so the result is never a surprise. Pressing Delete then builds a new PDF from the unmarked pages only.
Kept pages are untouched pages
Deletion here works by copying the surviving pages into a fresh document at the document level (pdf-lib, running locally in your browser) — not by rendering anything to images. The pages you keep are identical to the originals: text stays text, images keep their resolution, and the file shrinks in honest proportion to what you removed. Your original file is never modified, which makes experimenting free: mark aggressively, save, check the result, and if a page is missed, start again from the untouched original.
The one rule: a PDF keeps at least one page
An empty PDF is not a valid document, so the tool refuses — plainly, before doing any work — if the marks would remove every page. If you genuinely want a whole document gone, the file itself is yours to delete; if you want a single page out of it, that is Extract Pages' job. And if the pages you want rid of sit in the middle of a document whose order also needs work, Organize PDF deletes and rearranges in one grid.
Private by design
Like every CalcViso file tool, this one runs entirely in your browser. The file you choose is read by this page, processed on your device, and offered back as a download — it is never uploaded to a server, never stored, and never seen by anyone else. Close the tab and it is gone from memory.
Worked example
Press the sample button to load a 6-page sample, then type “2, 5” in the range box and press Mark these pages: thumbnails 2 and 5 turn red, and the stats promise 4 pages remaining. Press Delete marked pages and open the download — it holds sample pages 1, 3, 4 and 6, in order, with 2 and 5 simply gone.
How to use this tool
- Drop your PDF onto the box (or create the sample) and let the thumbnails render.
- Mark pages by typing ranges (2, 4-6) and pressing Mark these pages, or by clicking thumbnails.
- Check the stats: “Pages remaining” is the size of the file you are about to save.
- Press Delete marked pages and download the result.
- Open it and flick through — the kept pages should read in sequence with no gaps in the content.
Delete or extract? The two directions of one cut
Deleting and extracting are the same operation seen from opposite sides: delete keeps everything except the marked pages; extract keeps only the marked pages. Choose by whichever set is smaller to describe. Removing a cover and a blank from a 40-page report is a deletion (“1, 40” — well, and the blank). Keeping three relevant pages from the same report is an extraction (“12-14”). Both tools copy pages losslessly, so the choice costs nothing in quality — it is purely about which list is shorter to type.
