Does PDF Merge upload my documents anywhere?

No. The merge flow is designed to run in your browser so your PDF files stay on your device.

Can I reorder files before merging?

Yes. Use the Up and Down controls in the merge queue to change the final document order.

Why would a PDF merge fail?

Corrupted, unsupported, or unusually structured PDF files can fail to merge cleanly. If that happens, try a different file export or a simpler source document.

Can I merge just one PDF?

No. You need at least two PDF files to create a merged output.

PDF Merge | TinyToolbox

Upload two or more PDF files, reorder them in the merge queue, and click Merge PDF to download a combined document. The tool is designed for simple browser-based merging workflows where you want one file from multiple source PDFs without sending anything to a server. It works best when the source PDFs are standard documents rather than heavily encrypted or corrupted files.

Add your PDF files

Drop multiple PDF files into the uploader or browse for them from your device.

Arrange the merge order

Move files up or down in the queue so the final document follows the order you want.

Start the merge

Click Merge PDF to combine the queued documents into one downloaded file.

Review the output

Open the merged PDF and confirm the order and content before sharing it onward.
