Frequently Asked Questions (FAQ)

How many PDF files can I merge at one time? Because Vican Tools processes documents locally via WebAssembly, you can merge dozens of files at once, limited only by your computer's RAM.

Does merging decrease text or image quality? No. The merge process losslessly combines internal PDF object streams without re-compressing or degrading vector text and graphics.
