How to merge PDF files online
- Choose at least two PDF files from your device.
- Check the file list. Files are combined in the order you add them; remove and re-add a file if you need to change that order.
- Click Merge PDFs. Keep the tab open while your browser combines the pages.
- Download merged.pdf, open it and check the page count and order before sharing.
Combine documents without uploading them
The PDF merger processes files in your browser. It does not send document contents to a server or save them to cloud history. No signup, payment or watermark is required for local merging. Download the result before closing the tab.
Example: one PDF for an application
Add a cover letter first, then your résumé and supporting documents. The merged file keeps each source page’s dimensions, so portrait and landscape pages can appear in the same output. If you need to rearrange individual pages afterwards, use Organize PDF.
Questions about merging PDFs
Does merging compress my files?
No image downsampling is applied by the merge tool. It copies pages into a new PDF. File size can change when the document is rebuilt. If your upload has a size limit, try Compress PDF after merging and review the result.
Can I combine scanned PDFs?
Yes, if they are readable PDF files. A scan stays an image; merging does not perform OCR or make scanned text searchable.
Will signatures, bookmarks and fillable fields survive?
The merger combines page content, not every document-level feature. Do not rely on it to preserve interactive form fields, bookmarks, attachments or certificate-backed signatures. Keep your originals and check the exported PDF.
Why does a large or protected PDF fail?
Available browser memory limits the size of a merge. Try fewer files on a desktop browser. Password-protected or damaged PDFs may fail; open an unlocked copy you are permitted to use. Your originals are not modified.
