Merge PDF — frequently asked questions

Can I merge PDF files without uploading them to a server?

Yes. This merge tool runs entirely in your browser — the PDFs are read and combined locally on your device and never touch our servers. Open your browser's Network tab while merging to verify there are no uploads.

How many PDFs can I combine at once?

There is no fixed cap. Because merging happens locally instead of through an upload, the practical limit is your device's memory rather than a server quota — combining a large batch of typical documents works fine.

Will merging change the quality or formatting of my PDFs?

No. The pages are copied into the new document as-is — text, fonts, images and vector graphics are not re-rendered or recompressed, so the merged file looks identical to the originals.

Can I change the order of the files before merging?

Yes. After adding your files, drag the thumbnails into any order — the numbered badges show the final sequence. To rearrange individual pages within a file, use the Organize PDF tool instead.

Can I merge password-protected PDFs?

Encrypted PDFs can't be read by the in-browser merger. Remove the password first with the Unlock PDF tool (you'll need the password if the file requires one to open), then merge the unlocked copies.

Is merging free, and will the result have a watermark?

Merging is free, with no watermark on the output and no account required. You get a clean, single PDF.

After merging, people often…

  Shrink the merged file before emailing it.

• Protect PDF

• Sign PDF

  Place your signature on the finished file.
