Quick answer

The simplest method

ToolCrix merges PDFs locally: your browser reads the selected documents, copies their pages into a new PDF in memory, and downloads the result. The source files are not transferred to a merge server.

When this method makes sense

A no-upload workflow is useful for financial records, client contracts, ID documents, HR files, and any material governed by workplace or confidentiality rules.

Questions

Frequently asked questions

Are the merged files stored by ToolCrix?

No. The source files and merged output are processed in your browser and are not stored on a ToolCrix file server.

Can local PDF merging work with large files?

Yes, although the practical limit depends on the memory available on your device and browser.

Does the output contain the original metadata?

Page content is preserved, while document-level metadata can vary according to how the new PDF is assembled.
