About this tool
Merging PDFs is the most common document task there is: combining scanned pages into one file, assembling a report from separate chapters, or attaching an ID to an application form. This tool combines any number of PDF files into a single document, entirely inside your browser. Nothing is uploaded — files are read by your own device, stitched together in memory, and saved straight back to your downloads folder.
Unlike most online mergers, you're not limited to whole files. Open the per-file page range option and you can pull just the pages you need from each source document — "1-3, 7" from one file, everything from another. You can even mix in JPG or PNG images, which are converted to full-size PDF pages automatically and merged in order.
There are no file count limits, no size caps beyond what your device's memory can handle, and no watermarks stamped on the result. One thing to know: PDF bookmarks (outlines) are not carried over when pages are copied between documents, which is a limitation of how PDF page copying works.
Frequently asked questions
Is there a limit on how many PDFs I can merge?
No fixed limit. Because merging happens on your device, the practical limit is your browser's memory — hundreds of typical documents are fine. Very large scanned files (hundreds of megabytes each) may be slow on older hardware.
Will the merged PDF have a watermark?
No. The output is a clean PDF with your pages and nothing else. The tool is completely free, with no premium tier holding features back.
Can I merge only some pages from each file?
Yes. Click "Pick pages per file" after adding your documents and enter a range like "1-3, 7" for any file. Files with no range entered are included in full.
Do my files get uploaded to a server?
No. The merging runs in JavaScript inside your browser. You can disconnect from the internet after the page loads and the tool will still work.
Are bookmarks and links preserved?
Links and form fields that live on a page are preserved. Document-level bookmarks (the chapter outline some PDFs have) are not carried over — this is a limitation of PDF page copying that affects nearly every merge tool.
