What PDF Merge helps you do
Combine two or more PDF files into a single document without uploading them to Haivix. The file list shows the final order, and simple move and remove controls let you correct the sequence before the merged PDF is created.
Files are processed entirely in your browser. Nothing is uploaded to Haivix servers.
How to use PDF Merge
- Add two or more PDF files, then move them into the order the recipient should read.
- Remove any incorrect file, then merge and download the combined PDF.
- Open the result and check pages before sending or uploading.
What you can do with PDF Merge
- Add multiple PDF files in one browser session.
- Move documents up or down to control the final page sequence.
- Remove an incorrect file before merging.
- Create and download one combined PDF locally on your device.
Example: assemble a client handoff
Add the cover page, proposal, supporting evidence, and terms. Arrange the files in the order the recipient should read them, then merge and open the downloaded PDF for a final page-by-page check.
For a long package, rename the source files with numeric prefixes before adding them. That gives you a reusable source order and makes future revisions easier to assemble.
What to know before you start
- Encrypted or damaged source files may need to be unlocked or repaired before they can be merged.
- Browser memory limits depend on the device, so very large scanned files can take longer or fail on low-memory phones.
- Merging combines pages but does not automatically optimize image quality, bookmarks, form behavior, or file size.
