About PDF Toolbox
PDF Toolbox is an independent project by a small team of web developers. We built it because most sites that call themselves a “free PDF converter” quietly upload your documents to their servers. Our live tools don't: they run entirely in your browser, on your device, and your files are never transmitted anywhere.
Why we built this
PDFs are often the most sensitive files people handle online — contracts, invoices, medical letters, ID scans, payslips. Yet the standard workflow for “merge two PDFs” has long been: upload both files to a stranger's server, wait, and download the result, trusting a privacy policy you never read to say what happens to the copies. We thought that was backwards. Modern browsers are more than capable of reading, rewriting, and rendering PDF files locally, so that is what this site does. When you merge, split, compress, rotate, or sign a PDF here, the work happens in JavaScript on your own machine. Close the tab and nothing persists.
The site is deliberately simple: static HTML pages, one shared stylesheet, and a small amount of JavaScript. There are no accounts, no upload endpoints, and no server-side processing at all — in fact, the live tools work even if you save the site to disk and open it from a local folder with no internet connection.
What this site does
- Live tools (merge, split, compress, rotate, sign, image conversion, and many more) process your files entirely in your browser using open-source PDF libraries. Nothing is uploaded; the output is generated on your device and offered as a download.
- Guide pages cover jobs a browser genuinely cannot do well — such as high-fidelity Word-to-PDF conversion or true PDF encryption — and honestly explain the reliable ways to do them with software you already have, instead of pretending a lossy in-browser approximation is the real thing.
- The blog publishes practical, tested advice on working with PDFs, written by us, not syndicated.
What this site does not do
- It does not upload, store, scan, or analyze your documents. There is no server that could receive them.
- It does not require an account, an email address, or payment for any tool.
- It does not set analytics cookies unless you explicitly accept them in the consent banner — and it works identically if you decline. Details are on the Cookies & GDPR page.
- It does not claim capabilities it lacks. Where a conversion is approximate (for example, reconstructing an editable Word file from a PDF), the tool page says so plainly.
Who we are
We are a small team of web developers who have spent years building document-handling software professionally. This site is a side project, funded out of pocket; the ad slots and affiliate links you may see marked on some pages are inactive placeholders. We are not affiliated with Adobe or any other PDF software vendor. PDF Toolbox exists because we wanted these tools ourselves and figured other people would too.
