Merge PDF

Combine up to 20 PDF files into a single document with drag-to-reorder support.

Ideal for job applicants combining CV, cover letter, and portfolio into one file.

How to use it

  1. Upload your PDFs

    Click the upload area or drag and drop several PDF files at once. They load straight into your browser — nothing is sent anywhere.

  2. Set the order

    Drag the rows up or down to arrange the files in the exact sequence you want them to appear in the final document.

  3. Merge and download

    Click Merge PDF, give the combined file a name, and download it. The whole thing happens locally in a second or two.

Why use this tool?

Sending someone five separate PDF attachments — a CV, a cover letter, two certificates, and a portfolio — is awkward to open, easy to lose, and reads as disorganised. Recipients have to download each one, guess the right order, and juggle multiple tabs. Combining everything into one tidy, correctly ordered document solves all of that in a single click, and it is one of the most common things people need a PDF tool for. This merger does it instantly and privately, right in your browser. It uses pdf-lib to stitch your files together on your own device, so confidential contracts, financial records, or personal documents are never uploaded to a server — there is no account, no watermark, and no daily limit. You stay in control of the sequence: drag the files into the exact order you want before combining, and download a clean single PDF with the filename of your choice. Because the original page content is copied rather than re-rendered, text stays selectable and quality is untouched.

Frequently asked questions

How many PDFs can I merge at once?

Up to 20 PDFs in a single merge. You can run the tool again on the result to combine even more.

Does my file get uploaded to a server?

No. All merging happens in your browser using pdf-lib, so your files never leave your device — safe for confidential documents.

Can I choose the order of the files?

Yes. Drag the uploaded files into any order before merging, and the final PDF follows that exact sequence.

Is there a file size limit?

Each PDF can be up to about 100MB. For very large combined sizes the merge simply takes a little longer, since the work runs on your own computer.

Will the quality or text change?

No. Pages are copied as-is, so text stays selectable and images keep their original resolution — there is no recompression.

Are bookmarks, links, and form fields kept?

Page content is fully preserved. Some interactive elements such as bookmarks and form fields may not carry across when files are combined.

Can I merge PDFs on my phone?

Yes. The tool works in any modern mobile browser — upload the files from your device and download the merged PDF back to it.

Is it free and watermark-free?

Completely free, with no sign-up, no watermark, and no cap on how many times you can merge.
