PDF Tools
Merge PDFs or split them into pages – all local in your browser, nothing is uploaded.
Everything happens locally in your browser – your PDFs are never uploaded or stored.
Merge several PDF files into one document in any order, or take a PDF apart: extract a page range like '1-3, 5' as a new PDF or save each page as its own file.
The crucial difference from most online PDF services: your files are never uploaded. All processing happens with JavaScript right in your browser – even sensitive documents like contracts or certificates stay 100% on your device.
Frequently asked questions
Are my PDFs uploaded to a server?
No, never. Merging and splitting run entirely locally in your browser. You can even use the tool offline after the page has loaded.
Are there limits on file size or page count?
No artificial limit – the boundary is your device's memory. Typical documents with hundreds of pages are no problem.
Do password-protected PDFs work?
Encrypted PDFs often can't be processed. Remove the protection beforehand using the password in your PDF program.
