How to merge PDF files — step by step
Add your PDF files
Click the upload area to select multiple PDFs, or drag and drop them directly. You can add files from any folder on your device. Each file is read into local browser memory only.
Arrange the order
Drag files into the sequence you want them to appear in the final document. The first file in the list becomes the first pages of the merged PDF.
Click Merge PDF
The tool combines all pages from all files into a single PDF document. Page content, images, and links from each source file are preserved exactly as they appear in the originals.
Download the merged file
Click the download button to save the combined PDF. The file is generated locally and downloaded directly — no server, no wait, no signup.
No upload. No watermark. No daily limit.
Smallpdf and iLovePDF both restrict free users to 2 merge operations per day and add watermarks to output unless you pay. TrulyFreeTools imposes no daily caps and adds no watermarks — the merged PDF you download is identical to what you would receive from a paid tool.
All processing runs inside your browser tab using WebAssembly — your files never travel anywhere. Think of it like a desktop application that lives in a browser window. You could turn off your internet connection after the page loads and it would still work. That's how local the processing is.
Frequently asked questions
Can I merge more than 2 PDFs at once?
Yes. Add as many files as needed and rearrange them before merging. No limit on the number of files per session.
Does merging PDFs affect quality?
No. Merging combines page streams without re-encoding content. Images, text, and formatting in source files are preserved exactly.
Is there a page limit?
No server-imposed limit. The practical constraint is device memory. Merging documents with several hundred pages works on any modern desktop.
Will hyperlinks and bookmarks be preserved?
Hyperlinks within individual pages are preserved. Document-level bookmarks from source files are not automatically unified in the current version.
How do I merge PDFs on iPhone without an app?
Open this page in Safari on your iPhone, upload your PDFs, arrange the order, and tap Merge. The merged file downloads to your Files app. No installation required.
Can I merge password-protected PDFs?
Remove the password first using the Remove PDF Password tool on this site, then merge the unlocked files. Encrypted PDFs cannot be read by the merge engine.
