Local merge workflow
Select the PDFs, order them carefully, merge them in the browser, then open the generated file and verify page order before sending it.
- Use descriptive file names before selecting files.
- Put source PDFs in the intended order.
- Review the merged output before deleting originals.
- Split or remove pages first if only part of a document should be shared.
When to split before merging
If only a few pages are needed from a larger document, split the source first. Merging whole documents can accidentally include pages that should not be shared.
Limits to know
Browser-local PDF work depends on available memory and browser PDF parsing. Very large, encrypted, or damaged PDFs may fail and need dedicated desktop tooling.
FAQ
Are PDFs uploaded during local merge?
No. The merge workflow runs in your browser and generates a new local PDF.
Does merging PDFs compress them?
No. Merging combines pages. Use the PDF Compress tool for a local rewrite, and expect image-heavy PDFs to remain large.
