Merge PDF

Combine several PDFs into a single file, in whatever order you choose. Everything runs in your browser, so no document is uploaded.

The Merge PDF tool combines several files into a single document, keeping the order you set in the list. Everything runs in your browser, so your documents never leave your computer.

After adding the files, you can drag the list items to reorder them before generating the result. The final order in the combined PDF matches the displayed sequence exactly.

Merging copies pages directly with pdf-lib, preserving text, images, embedded fonts and the original resolution of each file. There is no recompression or quality loss during the join.

It is ideal for gathering contracts, reports, résumés, receipts and study materials that were split across several files. The result is ready to save or share with a single click.

When to use it

• Gathering several payment receipts into one PDF to send to your accountant.
• Combining chapters of a report that were saved as separate files.

Limitations

• No OCR: scanned pages stay as images and do not become searchable text.
• Password-protected documents must be unlocked before merging.

Step by step

1. Select the PDFs you want to combine or drag them into the area.
2. Reorder the list until the sequence looks right to you.
3. Click Merge PDFs and save the final file.

Frequently asked questions

Does file order matter?

Yes. The final PDF follows the list order exactly. You can drag items to reorganize them before merging.

Are my files uploaded to any server?

No. Merging runs entirely in your browser. Your documents stay on your device.

Can I merge PDFs with different page sizes?

Yes. Each file keeps its original page size, so the result may alternate between A4, Letter and other formats.
