PDF Merger
Combine multiple PDFs into one in your browser
About this tool
PDF Merger is a free PDF tool that combines multiple PDF documents into one file. Reorder source files with up/down controls, optionally pick a page range per file using formats like "1-3, 5, 7-10", and download the result without watermarks or signup. Page content, text, images and most annotations are preserved when merging contracts, scans and reports.
How to use
- Add PDF files. Drop your PDFs into the upload area, or click to choose multiple files from your device.
- Reorder files. Use the up and down buttons on each file card to set the merge order. Files merge top to bottom.
- Pick page ranges (optional). For each file you can leave it empty for all pages, or enter ranges like "1-3, 5, 7-10" to include only those pages.
- Merge and download. Press Merge. The combined PDF is built entirely in your browser, then a result panel appears with a Download button.
FAQ
Are my PDF files uploaded to a server?
No. PDFs are loaded, merged and saved entirely inside your browser. Files never leave your device.
How many files can I merge at once?
There is no fixed limit. We recommend keeping the combined size under about 200 MB on desktop and 50 MB on mobile to avoid memory issues.
Can I merge password-protected PDFs?
Encrypted PDFs are not supported. Remove the password first using your PDF reader, then merge the unprotected copy.
Can I pick only some pages from each file?
Yes. Each file has a range field. Enter values like "1-3, 5, 7-10" to include only those pages from that file.
Will bookmarks and form fields be preserved?
Page content, text, images and most annotations are preserved. Cross-file bookmarks and some interactive form fields may not carry over.
How do I merge PDF files for free without watermarks?
Use this tool. All merging runs in your browser — no account, no watermark, no file size limits shown after download. The output PDF is yours, clean.
