The uploaded file format is already matching the requested conversion format. Compression will still apply.
WebP compression preserves alpha transparency channel presets. Converting transparent PNGs to JPEGs will discard transparency backgrounds.

How to use Merge PDF
Combine multiple PDF files in the order you choose. Processing happens locally in your browser with no account or remote upload.
-
01
Add the PDF files
Choose two or more PDFs. Each selected document is read locally in your browser.
-
02
Arrange the file order
Place the documents in the sequence they should appear in the combined output.
-
03
Merge and verify
Create the new PDF, download it, and confirm the first page, final page, total page count, and file order.
No account required
Works in your browser
Review important output
- Input
- Two or more PDF files
- Output
- One combined PDF
- Processing
- Local with PDF-lib
Example: combine a report package
- Input
- Cover.pdf, Report.pdf, and Appendix.pdf
- Result
- Arrange them in that order to create one document with the cover first and appendix last.
Limits and checks
- Encrypted, password-protected, malformed, or unusually large PDFs may not open in the browser.
- Merging combines documents; it does not edit existing page content.
- Browser memory determines the practical number and size of files that can be processed at once.
Merge PDF questions
Does merging reduce PDF quality?
The tool combines PDF pages rather than intentionally recompressing their visible content. Always inspect the downloaded file.
Can I change the order?
Yes. Arrange the selected files before creating the merged PDF.
Are the PDFs uploaded?
No. Supported files are processed in the active browser session and are not sent to a Beginware file-processing server.
