Private by design
Most online PDF tools upload your files to their servers. This one doesn't: the PDF is put together in your browser with the open-source pdf-lib library, so contracts, bank statements and ID documents stay on your device. It even works offline once the page has loaded.
Merging PDFs and images together
Add JPG, PNG or WebP images alongside your PDFs and each one becomes a page. Choose The same shape as the image to make the page fit the picture, or A4 or US Letter for standard printable pages with a small margin.
What carries over
Pages keep their text, images, links and layout exactly. Bookmarks (the outline in the sidebar) aren't copied, and fillable form fields may no longer be fillable in the merged file. Fill in forms before merging them.
Frequently asked questions
Is there a limit on files or pages?
No fixed limit. Very large files depend on your device's memory, but hundreds of pages are fine on most computers and phones.
Can I merge password-protected PDFs?
Not directly. Open the PDF with its password and save a copy without one, then merge that copy.
Can I merge JPG files into a PDF?
Yes. Add images with your PDFs, or on their own. For images only, the Image to PDF tool has more page options.
Are my files uploaded?
No. Everything happens in your browser.
