Add your PDFs
Drag and drop PDF files (up to 50 MB each) or click to browse. Each file's page count is shown so you can verify before merging.
- 2
Arrange the order
Use the arrow buttons to arrange the files top to bottom — the first file's pages come first in the merged document. Remove any file you don't need.
- 3
Merge and download
Click Merge PDFs, then download the combined file. Nothing is uploaded — your documents stay on your device.
Frequently asked questions
- Are my PDFs uploaded to a server?
- No. ToolSahara merges your PDFs entirely inside your browser using local processing. Your files never leave your device, and nothing is stored or transmitted anywhere.
- Do merged pages keep their original size and quality?
- Yes — merging simply joins the existing pages, so every page keeps its original size, orientation, and quality. Nothing is re-rendered or compressed.
- Is there a file size or file count limit?
- Each file can be up to 50 MB. There is no fixed file-count limit, but very large merges depend on your device's memory — if merging stalls, try fewer files at a time.
- Can I merge password-protected PDFs?
- Password-protected (encrypted) PDFs cannot be merged because the browser cannot read their pages. Remove the password with your PDF software first, then merge.
- One of my files was rejected. What can I do?
- The file may be corrupted or not a real PDF despite its extension. Try opening it in a PDF reader — if it opens, print or save it again as a new PDF and retry.
