Merge PDF
Combine several PDF files into one PDF, in the order you choose, with page previews and per-file progress. Your files are processed in your browser and are never uploaded.
Files you choose stay on your device — they are not uploaded to Tools99.

A good use for this
Joining chapters, scanned pages, or separate reports into one document to share or print, without uploading anything.
Limits
The merged file keeps the pages as they are; it does not re-flow text, compress images, or fix a damaged PDF. Very large files may be slow because everything runs in your browser.
