Booklet printing
The booklet layout reorders pages (e.g. 8-1, 2-7, 6-3, 4-5 for an 8-page document) so that when you print double-sided, flipping on the short edge, and fold the stack, pages read in order. Blank pages are added to make a multiple of four. Pages are placed as vectors, so text stays sharp.
🔒 Your files never leave your device
bopdf processes your documents locally with JavaScript (pdf-lib and Mozilla pdf.js) inside your browser tab. Your PDF is never uploaded, stored or seen by us — you can even disconnect from the internet after the page loads and the tool keeps working. When you close the tab, everything is gone.
Frequently asked questions
Which paper size is used?
The size of your first page, turned landscape for 2-up and booklets.
Are my files uploaded to a server?
No. Everything happens in your browser on your own device. Files are never sent over the internet, which makes bopdf suitable for confidential documents.
Is there a file size limit?
There is no fixed limit, but very large files (hundreds of MB) depend on your device memory. On phones, files up to about 100 MB usually work well.
