PDFs are the format people send when the layout has to survive — contracts, tickets, scans, reports, receipts. Almost every edit you need is a page-level operation: join these two files, pull out pages 4–7, delete the blank scan, put the appendix at the end. This is how those operations work, which ones browser tools can do honestly, and what to check before you send the result on.
Why page surgery is the common case
A PDF is a container: pages, fonts, images and a cross-reference table that records where each object lives. That structure is exactly why page-level edits are safe and cheap — copying a page into another document or dropping one does not touch the content streams inside the pages you keep. Nothing is re-compressed, no text is re-laid-out, and the fonts stay embedded. The pixels and the words come out exactly as they went in.
Merging: combining sources into one file
Merging is the operation people need most, and the one where order matters. Merge PDF takes any number of files, lists them so you can see the sequence, and lets you move a document up or down before writing the output. A favourite trick: put a one-page cover sheet first, or merge the signed page from one file into the body of another.
- Merge contracts with their annexes, or a report with its appendix.
- Combine a scanned signature page with an otherwise digital document.
- Pull several receipts into a single expense file before submitting.
- Assemble a portfolio from one-page exports of other formats.
Splitting, extracting and deleting
Three operations look similar and answer different questions. Split PDF turns one document into several — by every page, by a fixed chunk size, or by the ranges you list. Extract PDF Pages pulls selected pages into a new document and leaves the original alone. Delete PDF Pages does the opposite: keeps everything except the pages you mark.
| You want to… | Use | Result |
|---|---|---|
| Keep pages 4–7 of a 20-page file | Split or Extract | One new 4-page file |
| One file per page | Split (every page) | 20 single-page files |
| Remove a blank scan | Delete PDF Pages | The original minus that page |
| Cut a 40-page report into 10-page chunks | Split (fixed size) | Four 10-page files |
Range syntax is worth knowing: "1-3, 7, 12-15" means the first three pages, page seven, then twelve through fifteen. Whitespace is ignored, so a hand-typed range still works.
Reordering and rotating
Scanned batches frequently arrive in the wrong order, or a page gets fed in upside down. Reorder PDF Pages shows thumbnails of the real pages and lets you drag them into a new sequence; Rotate PDF turns individual pages or the whole document in 90° steps, which is the fix for landscape pages captured in portrait.
Watermarks, page numbers and finishing touches
Once the pages are in the right order, presentation work is cheap. Watermark PDF stamps text across each page — useful for marking drafts with DRAFT or CONFIDENTIAL, with control over size, rotation, opacity and position. Add Page Numbers prints a page counter in the corner or the footer, with the starting number and format you choose, which is what turns a stack of exports into something that reads like a document.
Making the file smaller, or pulling content out
If the result is too heavy to email, Compress PDF reduces it, and the page-level operations above never inflated it to begin with — nothing was re-encoded. When the target system wants images rather than a document, PDF to Image rasterises pages to PNG or JPEG at the resolution you pick; when it wants text, PDF to Text extracts the character stream. In the other direction, Image to PDF turns photos and screenshots into a document, with the SEO pages for the common single-format cases (JPG to PDF, PNG to PDF) covering the one-click version.
A short checklist before you send the file
- Open the result and scroll through it — page order problems are obvious visually.
- Check the page count in the status bar against what you intended.
- Confirm nothing confidential was left in from the source file.
- Re-check metadata if the document is going outside your organisation.
That browser-first model is not limited to PDFs: the same reasoning applies to image metadata hygiene and to any file you would rather not hand to a server.
