- PDFs and pictures together
- Merge two files or twenty, and mix in JPG, PNG, WebP or iPhone HEIC pictures: each becomes one page.

About this tool
Merging usually means uploading sensitive paperwork such as ID scans, bank statements or signed contracts to someone else's server. This tool does the same job inside your browser tab using the open-source pdf-lib library, so the files never travel over the internet.
Each page is copied into the new document exactly as it was, which keeps text selectable and images sharp. A picture becomes a page the size of the picture itself, turned the right way up if a phone saved it sideways. If you need only some pages from a file, use Split PDF first and then merge the result.
Frequently asked questions
Are my PDFs uploaded to a server?
No. The merge runs entirely in your browser. Once your files are added, it even finishes with the internet switched off.
Is there a file size limit?
There is no upload limit because nothing is uploaded. Very large files, in the hundreds of megabytes, depend on how much memory your device has.
Can I merge password-protected PDFs?
Not directly: a locked file is marked "Password-protected" in the list. Open it in a PDF reader, remove the password, save it, and then merge it here.
Are links and bookmarks kept?
Page content, text and most links are kept. The bookmark outline and fillable form fields may not carry over to the merged file.
Can I merge a PDF with JPG images?
Yes. Add JPG, PNG, WebP or iPhone HEIC pictures with your PDFs and drag them into place. Each picture becomes one page at its own size, so the photo of a receipt can sit right after the invoice it belongs to.
Does it work on iPhone and Android?
Yes, on iPhone, iPad and Android, without an app: merge PDFs on an iPhone in Safari, or combine PDFs on Android in Chrome. Choose the files from Files or Google Drive and drag them into order. On an iPhone the merged file goes to the share sheet (Save to Files), and Android Chrome asks where to save it. Two PDFs or twenty, it works the same, on a Chromebook too.
Is this online PDF merger free?
Yes. Merging is free, with no sign-up and no watermark. The files are joined in your browser, so they are never uploaded.
Can I add a photo from my camera as a page?
Yes. Tap "Take a photo" on a phone or "Use the webcam" on a computer, under the box before you add files or under "Add more" once the list shows; each shot joins the list as a page at the photo's own size. Add your PDFs with "Add more" and drag everything into order. With your phone linked through the code under "Use your phone's camera", the photos you take on it keep arriving in the list while you work.
PDF merge kaise kare, 2 PDF ko ek kaise banaye? (How do I merge two PDFs into one?)
Mobile se bhi hota hai aur computer me bhi, aur mobile me koi app nahi chahiye: yeh page kholein, PDF files chunein, tarteeb dein aur "Merge PDFs" dabayein. On a phone or a computer, open this page in Chrome or Safari, tap the box to choose two or more PDFs from Files or Google Drive, put them in order and tap "Merge PDFs". The merged file is saved to your device; nothing is uploaded.
