About Merge PDF
Scattered PDFs are a fact of modern paperwork: an invoice here, a signed form there, a report in three chapters. Merging combines them into a single document that's easier to file, email, and print. Add two or more files, arrange them with the up/down controls, and download one combined PDF. Pages are copied exactly as they were, with no recompression and no watermarks.
Order is everything, so set the sequence before you merge: contracts read front-to-back, and a misplaced appendix is confusing. Each file can be up to 50 MB, and there's no limit on how many files you add. The page keeps working offline once it loads.
Merging organizes; it doesn't optimize. The combined file is roughly the sum of its parts, so merge first and compress or delete pages after if size matters. Mixed page sizes are kept as they are, which can look odd if your sources differ. Standardize the paper size when you can, and always open the result for a final check.

Tips for best results
- Set the order first. A misplaced section confuses readers, so arrange your files before you merge.
- Merge, then slim down: the output is the sum of its parts, delete unneeded pages or compress after merging.
- Watch mixed page sizes: sources with different dimensions keep them, so standardize paper size where possible.
- Name files clearly: descriptive filenames make the merge order obvious before you arrange them.
- Check the result: open the merged PDF and skim for ordering or orientation surprises.
- Works offline: after the page loads, merging needs no connection, handy on planes or secure networks.
