How to merge PDF files
- Drop your PDFs into the box above, or press "Choose files".
- Put them in the order you want. The list order, not the order you added them, decides the result.
- Press "Merge", then "Download PDF".
There is nothing to install and no account to create. It works the same in Chrome, Safari, Edge and Firefox on Windows, Mac, iPhone and Android.
Combine only some pages
To use just part of a PDF, type a range in its "Pages" box, for example 1-3,5 (pages 1 to 3, and page 5). 2- means page 2 to the end. Leave it empty for all pages. You can add the same file twice with different ranges to interleave or reorder pages.
Combine images and PDFs into one file
JPG and PNG images go into the same list as your PDFs. Each image becomes one page, so you can mix scans, photos and PDFs into a single document, for example an application packet or a set of receipts to email as one attachment. JPG and PNG are embedded as they are, without re-encoding (a JPG with an orientation flag, such as a portrait phone photo, is redrawn once so it appears upright). WebP, GIF, BMP and AVIF are redrawn as JPG if your browser can open them; transparent areas become white and GIFs keep only the first frame. HEIC (iPhone photos) works only in browsers that can open it, such as Safari and Chrome on macOS; otherwise convert first with the HEIC to PDF page or HEIC to JPG converter.

Limits and notes
- Password-protected (encrypted) PDFs cannot be merged. This page cannot remove a password. If you know it, open the file in an app such as Acrobat or Preview, save an unprotected copy, and add that copy.
- Up to 200 files and 500 MB in total per merge. For more, merge in groups and then merge the results. Fewer files can still fail on phones with limited memory.
- Damaged files and files that are not PDFs or images are not added; the page tells you why.
- Page content (text, images, fonts) is copied as is. This page does not compress, so the merged file is about the size of the originals combined.
- Bookmarks, form fields and link annotations may not carry over. A digital signature in a signed PDF becomes invalid after merging.
- Characters not allowed in file names (
/ \ : * ? " < > |) are replaced with_.
FAQ
Are my PDFs uploaded to a server?
Not by this page's code. Merging uses pdf-lib, an open-source library hosted on this same site, and the page makes no network calls of its own. You can confirm in your browser's network tab while merging. We cannot speak for your browser or its extensions.
Is there a daily limit, a watermark or a sign-up?
No limit on how many times you merge, no sign-up and no watermark. Each merge is capped at 200 files and 500 MB to keep your browser from running out of memory.
Can I merge password-protected PDFs?
No. An encrypted PDF cannot be read, so the page lists it as not added. If you know the password, save an unprotected copy in another app first. This page does not crack or bypass passwords.
Can I reorder individual pages inside a PDF?
You reorder whole files. To rearrange pages within one PDF, add that PDF several times and give each copy a page range such as "3" or "1-2", then arrange the copies in the order you want.
Will merging make the file smaller?
No. The merged PDF is roughly the sum of the originals. If you need a smaller file, shrink the images first with the image compressor.
Does it work on iPhone and Android?
Yes, in the phone's browser. Very large merges may fail on phones because of limited memory; merge in smaller groups if that happens.
