One field, three jobs
In Pages to keep mode, the order you type is the order you get — entering 3,1,2 doesn't just keep those three pages, it puts page 3 first, page 1 second, and page 2 last. That's the trick this tool leans on: reordering is just "keep everything, but in this order."
Pages to delete mode is the plainer option when you just want a few pages gone and everything else left in its original order.

What reordering a PDF actually does
A PDF stores each page as a self-contained object, with a separate structure recording the order they appear in. Reordering, rotating or deleting pages rewrites that structure rather than the page content itself, which is why the operation is lossless. Text stays selectable, vector artwork stays sharp, and embedded fonts are preserved — nothing is rasterised or re-compressed.
That distinguishes it from workflows people sometimes fall back on, like printing to PDF or exporting pages as images and reassembling them. Those approaches flatten everything, destroy selectable text, and typically multiply the file size several times over for a worse-looking result.
Common jobs and one caution
Most reordering work falls into a few patterns: a scanner produced pages in reverse, a double-sided scan interleaved fronts and backs in the wrong sequence, a cover page needs moving to the front, or blank separator pages need removing before sending a document to a printer. Rotation usually comes from a scanner feeding landscape pages through a portrait setup, and fixing it before the document is shared saves everyone tilting their heads.
The caution concerns what reordering does not carry with it. Internal links, bookmarks and a table of contents point at specific page targets, and depending on how a document was produced those references can end up pointing at the wrong pages once the order changes. Form fields and digital signatures are more fragile still — a signature covering the document as a whole will be invalidated by any structural change, because that is precisely what it exists to detect. If a PDF is signed or contains a filled form, work from an unsigned copy.
Common questions
How do I reorder pages?
Use "Pages to keep" and type the page numbers in the order you want them to appear, such as 3,1,2. The output PDF follows that exact order, which means this one field can keep, drop and reorder pages all at once.
What's the difference between the two modes?
"Pages to keep" builds the new PDF from only the pages you list, in the order you list them. "Pages to delete" does the opposite — it keeps everything except what you list, in the original order.
Is my PDF uploaded anywhere?
No. Pages are copied entirely in your browser using a JavaScript library. Nothing is sent to a server.
Does reordering pages reduce the quality of a PDF?
No. Pages are stored as self-contained objects, and reordering rewrites the structure that lists them rather than the content itself. Text stays selectable, vector graphics stay sharp and nothing is re-compressed, unlike exporting pages as images and reassembling them.
Will my bookmarks and internal links still work afterwards?
Not always. Bookmarks and internal links point at specific page targets, and depending on how the file was created those references can end up pointing at the wrong page once the order changes. Check them before sending an important document.
Can I reorder a signed or form-filled PDF?
A digital signature covers the document structure, so any structural change invalidates it — that is exactly what it is designed to detect. Form field data can also be affected. Work from an unsigned copy and apply signatures after the pages are in their final order.
