Combine PDF files locally

Merge PDF files privately in PDF Studio without sending documents to a server. ConvertRS uses a local Rust/WASM PDF engine, so your documents stay on your device while you reorder pages and download the merged copy.

Steps

Add two or more PDF files from your device.
Reorder the files so they appear in the desired output order.
Merge locally and download the combined PDF.

Best for

Combining multiple PDF files into one document.
Reordering PDFs before appending them together.
Private document workflows where files must stay local.

Why local

Your PDFs stay on your device.
The editing workflow runs with browser APIs and WebAssembly.
No filename, page content or PDF metadata is uploaded to ConvertRS.

Can I merge PDFs without uploading them?

Yes. ConvertRS reads and combines the PDFs in your browser using WebAssembly, so your documents stay on your device.

Can I choose the merge order?

Yes. Move PDFs up or down before merging; the output follows the order shown in the list.

Does merging preserve selectable text?

ConvertRS keeps the original PDF page objects instead of rasterizing them, so selectable text is preserved for typical PDFs.
