Add two or more PDFs, put them in order with the up and down arrows, and the tool copies every page into one new file called merged.pdf. Pages are copied exactly as they are, so text stays selectable and images keep their original resolution. Each file can be up to 250 MB, and there is no fixed cap on the number of files beyond your device's memory. Password-protected PDFs cannot be merged directly: remove the password first with Remove PDF Password, then add the unprotected copy. Bookmarks and document properties from the source files are not carried into the merged file, so add a new outline with Bookmark PDF if you need one. All processing happens in your browser and nothing is uploaded.

Frequently asked questions

How do I merge PDF files without uploading them?

Open this tool, add your PDFs and click Merge PDFs. The files are read and combined by your own browser, so they never reach a server. You can check this by switching off your internet connection once the page has loaded and merging anyway.

Does merging PDFs reduce quality?

No. Each page is copied into the new file as it is, without being re-rendered or compressed. Text stays selectable, vector graphics stay sharp and images keep their original resolution.

How do I change the order of the merged files?

After adding the files, use the up and down arrows beside each file name to move it. The files are joined from top to bottom. To reorder individual pages after merging, use Rearrange PDF Pages.

Can I merge password-protected PDFs?

Not directly. If any file is encrypted or damaged the merge stops and names that file. Remove the password with Remove PDF Password, or fix the file with Repair PDF, then add the new copy and merge again.

Is there a limit on how many PDFs I can merge?

There is no set limit on the number of files, and each file can be up to 250 MB. The real ceiling is your device's memory, so very large batches may be slow on older phones or laptops.
