Frequently asked questions
Is there a watermark, signup or daily limit?
None of the above. Drop a file in, get the result, download it.
How do the tools work without uploading my PDF?
The PDF libraries (pdf-lib, pdf.js, docx) are pure JavaScript and run on the page itself — no server round-trip required. Open DevTools, watch the Network tab while you process a file: nothing carrying your PDF is sent.
What is the maximum PDF file size?
There is no hard cap. Browser memory limits practical processing to ~200 MB on a modern laptop. Very large PDFs (500+ pages, or PDFs full of high-resolution scans) may slow the tab or run out of memory — your file is never lost, since it never left your device.
Do you keep logs of what people do with the tools?
No. We log anonymous page-view analytics, but we never receive your files. Browser "Do Not Track" preferences are respected.
Which browsers are supported?
The latest two versions of Chrome, Edge, Firefox and Safari (desktop and mobile). The tools rely on modern File API and WebAssembly features, so they will not work on Internet Explorer 11 or browsers older than 2021.
