Frequently asked questions

By default, headPDF processes files locally in your browser (client-side). That means your PDFs stay on your device. If we ever add server-based tools, they’ll be clearly marked inside the tool before you upload anything.

No. headPDF does not see, read, or store your PDF files. Most tools run locally in your browser, so files never leave your device.

We collect only anonymous technical statistics such as the number of processed files and their total size. We do not collect file contents, text, images, page data, or filenames. This information is used only to improve the product.

Add PDFs → open Options (optional) → reorder, rotate or delete pages → click Merge → download the final PDF.

With local processing, limits depend on your device and browser. Very large PDFs may be slower on mobile devices.

Yes. Use Options to preview pages, delete what you don’t need, and then split the remaining selection into new files.

You’ll download a ZIP file that contains multiple PDFs (for example: one per page or per range).

Some PDFs are encrypted or protected and may block editing by design. Try unlocking the PDF first if you have permission.

Large PDFs can be heavy for mobile devices. Try desktop, close other tabs, and process fewer pages at once.

Check if a browser extension blocks downloads or popups. On iOS, downloads may behave differently depending on the browser.
