Merge PDF files
Put several PDFs into one file. Reorder them before you merge. The documents never leave this browser.
No uploads. Runs on your device.
How it works
- Add two or more PDFs. You can drop a whole set at once.
- Move files up or down until the page order is right.
- Merge, then download a single PDF.
Questions
Are the files uploaded?
No. The merge runs in a background thread on your device. Closing the tab discards the bytes.
Will bookmarks and form fields survive?
Pages are copied into a new PDF. Visible page content is kept. Some viewer-specific extras, such as outline bookmarks, are not copied.
Can I merge a password-protected PDF?
No. Remove the password first. PDF4ALL does not ask for or store PDF passwords.
