FAQ
Common questions
- How do I merge PDF files online for free?
- Add your PDF files to the tool above, drag the rows to set the order you want, and click Merge. Your browser combines the files using pdf-lib and downloads the result immediately — no account, no upload, completely free.
- How do I combine two PDF files into one?
- Drop both PDFs onto the tool, confirm the order in the file list (drag to swap if needed), and click Merge. The tool combines them into a single PDF and downloads it in seconds. Add as many files as you like — there is no limit.
- Is there a free online PDF merger with no sign-up?
- Yes — this tool is completely free with no account, no credit card, and no usage limits. Everything runs in your browser using pdf-lib, so your files never leave your device.
- Is this PDF merger free to use?
- Yes — completely free with no account, no credit card, and no usage limits. Everything runs in your browser.
- Are my files uploaded to a server?
- No. Your files never leave your device. All merging happens locally in your browser using pdf-lib. Closing the tab discards everything.
- How many PDFs can I merge at once?
- There is no hard limit. In practice, very large batches (50+ files) may be slow depending on your device's memory. For most use cases — combining a few reports, chapters, or scans — performance is instant.
- What is the maximum file size?
- Each individual file can be up to 25 MB. This covers the vast majority of documents. For very large or scanned PDFs, consider compressing them first.
- Does the merged PDF preserve bookmarks, forms, and annotations?
- Basic page content (text, images, vector graphics) is fully preserved. AcroForm fields are copied but may lose interactivity depending on the original. Bookmarks (outlines) are not merged in this tool.
- Can I merge more than two PDFs?
- Yes. Add as many PDF files as you need and drag them into the order you want before merging.
