Frequently Asked Questions (FAQ)
Are my PDF files uploaded to your servers?
No, never. FileOmniTool uses WebAssembly and pdf-lib: the entire merging process takes place in your device's local RAM. No data ever leaves your computer.
Is there a limit on how many PDFs I can merge?
There are no arbitrary limits set by us. You can merge as many documents as your device memory allows.
