FAQ

How do I use the join tools to combine my files?

Select the appropriate tool for your file type, upload your documents or paste your text, and the processing will run on our servers to generate a merged result for download.

Is my data secure when using these merging utilities?

Yes. While processing occurs on Elysia Tools servers, text inputs are never stored, and all uploaded files are automatically deleted after 6 hours.

Do I need to install any plugins to join files?
