PDF Tools Suite
Seventeen tools for working with PDF files. Fifteen of them never send your document anywhere.
Pages
Rearranging what is already in a document: combining files, cutting them up, and moving, deleting or turning pages.
Marking up
Adding something to every page: numbering a document for print, or stamping it as a draft.
Getting things out of a PDF
Turning a document into something else: its words, or a picture of each page.
Making a PDF from something else
Photos, spreadsheets, Markdown and web pages, turned into a document.
Which tool do I want?
Several of these sound alike, and picking the wrong one wastes a couple of minutes. The differences that actually matter:
Split, extract or remove?
- Split cuts the whole document into several files, with no page left out. Use it to break a long report into sections.
- Extract takes the pages you choose into one new file and leaves the original untouched. Use it to pull out an appendix.
- Remove is the same operation phrased the other way: name the pages you do not want and keep the rest. If you find yourself selecting nearly every page in Extract, this is the shorter route.
Two ways to make a PDF from images
The Image to PDF Converter is the direct path: drop the files, choose a page size, download. The Image to PDF Maker lays them out as a board you can drag into order and turn individually. Use the first when the files are already named in order, the second when they are not.
Two ways to read the text
PDF to Text reads the text layer a document already contains, entirely in your browser, and returns nothing for a scan. PDF to Text with OCR adds recognition for pages that are images — and checks every page locally first, sending only the ones that genuinely need it. Start with the first; it will tell you if you need the second.
What running in the browser actually buys you
It is easy to treat "no upload" as a slogan. It has four concrete consequences, and they are the reason this suite is built the way it is.
| These tools | A typical upload service | |
|---|---|---|
| Where your file goes | Nowhere — it is read in the page | Onto a server you do not control |
| Size limit | Whatever your device can hold | Usually capped, often behind a paid tier |
| Speed | No transfer, so a big file starts instantly | Upload, wait in a queue, download |
| Works offline | Yes, once the page has loaded | No |
It matters most for what people actually put through these tools: contracts, invoices, bank statements, medical letters, scanned passports, unpublished drafts. A merge of two payslips should not require handing them to anyone.
What survives, and what does not
The tools that move pages about — merge, split, extract, remove, rearrange, rotate — copy pages across without re-rendering them. Text stays selectable, fonts stay embedded, images keep their resolution, and rotation is written as a value rather than by redrawing anything.
Two things do not survive, on any tool here or anywhere else, because they belong to the document rather than to the pages being copied: the bookmark outline and interactive form values. Flatten a form before processing it if the filled-in values matter.
Two tools necessarily rasterise, and say so plainly on their own pages: the image converter, which is the whole point of it, and the grayscale converter, because there is no way to recolour a PDF's drawing instructions from a browser.
Questions
Are my PDF files uploaded?
For fifteen of the seventeen tools, no. They open and rewrite the document inside your browser, so no copy is transmitted and none is stored. The two exceptions are named on this page and on their own pages: optical character recognition, which needs a trained model on a server, and the web page converter, which needs something to fetch a page from another site because a browser is not permitted to.
Is there a file size or page limit?
No fixed limit on the tools that run in your browser, because there is no upload to cap. The real constraint is the memory of your device: a desktop handles a few hundred megabytes comfortably, while a phone is happier with smaller jobs or with a long document split into passes.
Do I need to sign up or install anything?
Neither. There is no account, no email, no watermark on the output and nothing to install. Every tool works from the page in any current browser, on a phone as well as a desktop.
Which tool do I want for splitting a document?
Split cuts the whole document into several files with no page left out. Extract takes the pages you choose into one new file and leaves the original alone. Remove is the same operation phrased the other way, where you name the pages to delete. If you find yourself selecting nearly every page in Extract, Remove is the shorter route.
Will my document lose quality?
Not on the tools that move pages around. Merging, splitting, extracting, removing, reordering and rotating copy pages across without re-rendering anything, so text stays selectable and images keep their resolution. The two that necessarily rasterise are the image converter and the grayscale converter, and both say so on their own pages.
Can I use these on a phone?
Yes. Every tool is built for a small screen first, with controls large enough to tap and buttons rather than dragging wherever dragging would fight with scrolling. Very large documents are the one place a desktop is genuinely better, because everything is held in memory.
