About this tool
Add two or more PDFs, and images if you like, put them in the order you want, and download one merged.pdf. The files are read from your device and the result is built in this tab.
In what order are the files merged?
In the order shown in the list. Use the arrow buttons next to a file to move it up or down. Each image becomes one A4 page, scaled to fit.
Are my files uploaded?
Nothing is uploaded. The page can only make requests back to this site, and the site has no upload endpoint. You can confirm it in your browser's network panel.
Are there size limits?
Each file must be under 100 MiB. A batch can hold up to 30 files and 200 MiB, and the merged PDF can have at most 500 pages.
What gets lost when merging?
Merging copies pages into a new document. Editable form fields and bookmarks are not kept, and links and annotations may change. Keep your originals.
Can I merge a password-protected PDF?
No. Open a copy in a PDF viewer, save it without the password, and add that copy. PDFs with XFA forms or signature fields are not supported either.
