Combine PDFs into one file
Merging is useful when you have several parts of one document, such as scanned pages, invoices or application forms, and need to send them as a single file. Add your PDFs, put them in the order you want, and download the merged PDF.
Set the order
Files are merged from top to bottom. Use Up and Down beside each file to change the order. The list shows the number of pages in each file so you can check the total.
What is kept and what is not
Pages are copied exactly as they are, including text, images and fonts, so quality does not change. Document-level features such as bookmarks and interactive form fields may not carry over to the merged file. If you rely on them, check the result.
Password-protected and very large files
Protected PDFs cannot be merged. Remove the password in the app that created the file first.
Merging happens in your browser's memory, so many large files at once can slow down a phone. Merge in smaller groups, then merge the results.
Questions
- Is it free?
- Yes. There is no watermark, no signup and no daily limit for normal use.
- Are my files uploaded?
- No. Everything runs in your browser, so your PDFs never leave your device.
- Is there a limit on the number of files?
- No fixed limit. Very large files depend on your device memory, so merge in smaller batches if the page becomes slow.
- Is there a page limit?
- There is no fixed limit. Your device memory decides how much you can merge at once.
- Will merging reduce quality?
- No. Pages are not re-rendered, so the content stays the same.
- Can I reorder individual pages?
- Not in this version. Use Split PDF to extract pages in a custom order, for example by typing 5, 1, 3, and then merge the results.
