How to merge PDFs
Choose the files
Click Merge PDFs on the start screen and select all the PDFs at once, or drop them together onto the page. They are combined in the order you picked them.
Arrange the pages
Bullet PDF opens in Pages mode: drag pages or whole groups to reorder, rotate any that are sideways, delete the ones you do not need, and add more files with Insert file.
Download
Press Download PDF. Form fields, links and bookmarks from the first PDF are kept.
Merging without the mess
Any number of files
Combine as many PDFs as you like in one go, then add more between any two pages later.
PDFs and images together
Mix JPG, PNG, WebP and GIF images with PDF pages; each image becomes a page.
Drag to reorder
Thumbnails of every page: drag one or a selection to a new position.
Rotate and delete
Fix sideways scans and drop blank pages before you save.
Extract instead
Select pages and download just those as a new PDF, if you only need part of the result.
No file size cap
There is no upload, so there is no upload limit. Large files are limited only by your device's memory.
Questions about this tool
Is there a limit on how many PDFs I can merge?
No. Select as many files as you like; the combined document can be hundreds of pages.
Does merging keep the form fields and links?
Fields, links and bookmarks from the first PDF you open are kept. Pages from the other PDFs are copied in with their content and appearance intact.
Can I merge PDFs on a phone?
Yes. Use the file picker to select several PDFs at once (tap and hold, or use the Select option in your file browser), then arrange them in Pages mode.
Can I put the pages in a different order from the file order?
Yes. Pages mode shows every page as a thumbnail; drag them anywhere, including a group at a time.
How do I add a PDF to one I already have open?
In Pages mode choose Insert file, or drop the file between two page thumbnails.
Ready?
It opens in a second. Nothing to install, nothing to sign up for.
