A document job is usually a small, urgent thing: three PDFs that must become one before an email goes out, two pages a landlord wants, a scan that a portal rejects for being too big. None of it needs installed software, and none of it needs your contract travelling to a stranger’s server. This page is the door to both shelves of the site’s document work. The PDF shelf: Merge PDF, Split PDF, Images to PDF and Compress PDF. The text shelf: the case converter, the text line tools and the word counter. All seven run in your browser, all seven are free, and not one of them uploads what you drop into it.
Which tool do I need?
| The job you arrived with | The tool for it |
|---|---|
| Several PDFs that must become one file | Merge PDF |
| A few pages out of a long PDF, or one long scan to break apart | Split PDF |
| Photos or scans that must become one document | Images to PDF |
| A PDF that must fit under a size cap a form demands | Compress PDF |
| Text in the wrong capitalisation, or a list that needs a URL slug | Case Converter |
| A messy list with duplicates, stray spaces, no order | Text line tools |
| A draft that must hit a word or character limit | Word Counter |
Two of those jobs deserve a word on how they work, because it is not the usual way.
Compress PDF does not offer a “medium quality” slider. You type the cap the form demands — 100 KB, 500 KB, any number — and the tool searches for the highest quality that still fits under it, then tells you what it did. If even the lowest quality overshoots, it scales the pages down and tries again. Each page becomes an image in the process, which is exactly right for scans and wrong for a document whose text must stay selectable.
Split PDF takes page ranges the way a print dialog does: 1-3, 7, 12- means pages one to three, page seven, and page twelve to the end, in that order. One long scan containing several documents becomes several files with one command.
On the text shelf, the line tools have an order that matters: trim spaces first, then remove duplicates, then sort. Doing it the other way round leaves duplicates behind, because a single trailing space makes two identical lines look different. And the word counter updates as you type — it assumes 225 words per minute for reading time and 130 for speaking aloud, and states so on the page, because tools that quietly assume different speeds give different answers.
Are my files uploaded when I use these tools?
No. Each tool on this page states where the work happens, and for all seven the answer is: your own device. There is no queue, no upload limit and no “we delete your file within an hour” promise, because no copy of your file ever leaves your machine.
You do not have to take the page’s word for it. Open your browser’s developer tools, go to the network tab and use a tool with a small test file: a local tool shows no request carrying your file. Switch off your internet and the tool keeps working. The ten-second version of that check, and what it means for the sites that do upload, is written out in the guide why upload-based file tools are a privacy problem.
Which PDF jobs still need real software?
Being honest about the boundary is more useful than pretending there isn’t one. Four jobs:
- Reading a scan as text (OCR). A scanned page is a picture of words; making them searchable needs a real OCR engine.
- Editing existing text. A PDF stores positioned letters, not paragraphs, so changing a sentence means reflowing everything after it.
- Shrinking a text PDF that must stay selectable. The browser route rebuilds pages as images — right for scans, wrong for text.
- True redaction. A black rectangle is drawing on top of text, not removing it; the words stay in the file, selectable and copyable.
A fifth, simpler limit: a PDF that needs a password to open cannot be read here at all, by design — no server means nowhere to send the password.
For everything else — which is most PDF work on a normal day — a browser is faster, and the file never leaves your machine. The full walkthrough, including how to make a PDF from anything with “Save as PDF”, is in the guide how to work with PDFs without Adobe Acrobat.
What about the data hiding inside my files?
A PDF you send carries more than its pages: the producing application, creation and modification timestamps, and very often an author name taken from the account on the machine that made it. A proposal’s metadata naming the previous client is a real category of embarrassment.
The PDF tools here drop the producer and creator fields when they write a file, so merging or splitting does not stamp our name on your document and does not carry the old tool’s forward. What that does and does not protect against — and the checks worth running before anything public, corporate or redacted leaves your device — is in the guide the data hiding in files you send every day.
Is there a limit on file size?
For merging and splitting, the limit is your device’s memory — there is no server enforcing a quota (tool pages, checked 27 September 2026). Images to PDF takes up to 60 images per document; Compress PDF takes up to 50 pages. A hundred phone photos in one PDF would be an enormous file anyway: JPEG and PNG images are embedded as they are, without re-compression, so the document is about the size of the images combined.
The text tools keep your draft in this browser’s storage, so a reload does not lose it — and a Clear button empties it.
What comes next
Seven tools and three guides are the current shelf, not the finished one. New document tools land here as they are built and tested, under the same three rules: free, in your browser, nothing uploaded.
