Merge PDF files
Combine two or more PDFs into a single document. Drag to set the order, then download the merged file. Everything happens in your browser, so your documents are never uploaded anywhere.
100% private: files are processed in your browser and never uploaded to any server.
How it works
- Drop two or more PDF files into the box above, or click to choose them.
- Drag the files into the order you want them to appear in the final document.
- Click “Merge PDFs” and download the combined file.
When merging PDFs is the right move
Combining several PDFs into one is one of those small tasks that comes up constantly. You scan a document a few pages at a time and end up with a folder of separate files. You collect signed pages back from different people. You want to send a single attachment instead of five. Merging turns that scattered pile into one clean document that opens, prints and archives as a unit.
Because the pages are copied across untouched, merging is also lossless. Text stays selectable, images keep their resolution, and links and bookmarks survive. Nothing is re-rendered, so a merged PDF is exactly as sharp as the originals — it is just held in a single file now.
How order and page ranges work
The final document follows the order of the files in the list, top to bottom. Every page of the first file comes first, then every page of the second, and so on. If you need a different sequence, drag the files into place before merging, or use the up and down arrows.
If you only want certain pages from a file, split it first with the Split PDF tool to pull out the pages you need, then merge those. Because everything runs in your browser, chaining tools like this is instant — there is no upload between steps.
Doing it without uploading anything
Merging often involves private material — think of assembling a contract from signed pages, or combining bank statements for a mortgage application. Pdfect builds the merged file entirely in your browser using a PDF library compiled to run on your device, so none of those pages are ever uploaded. You can confirm it by going offline after the page loads: the merge still works, because there is no server involved.
Frequently asked questions
Is there a limit on the number or size of PDFs I can merge?
No. Because merging happens on your device, there are no queues, no daily limits and no maximum file size beyond what your browser can handle.
Are my PDFs uploaded to a server?
No. Pdfect merges PDFs with code that runs inside your browser. Your files never leave your device — you can even disconnect from the internet after the page loads and the tool keeps working.
Will the merged PDF keep the original quality?
Yes. Pages are copied into the new document as-is — text, images and vector graphics are not recompressed or altered.
Can I change the order of the files before merging?
Yes. After adding your files, drag them (or use the arrow buttons) to arrange them in any order. The merged PDF follows the order shown in the list.
Can I merge more than two PDFs at once?
Yes. Add as many files as you like — they are all combined into a single document in the order shown in the list. There is no fixed limit beyond what your browser can hold in memory.
Do bookmarks and links survive the merge?
Internal page content, text and images are preserved exactly. Links within the pages are kept; some document-level structures like bookmarks may be simplified, since the pages are copied into a fresh document.
